- *
- * @enum:
- * FT_LOAD_XXX
- *
- * @description:
- * A list of bit-field constants used with @FT_Load_Glyph to indicate
- * what kind of operations to perform during glyph loading.
- *
- * @values:
- * FT_LOAD_DEFAULT ::
- * Corresponding to~0, this value is used as the default glyph load
- * operation. In this case, the following happens:
- *
- * 1. FreeType looks for a bitmap for the glyph corresponding to the
- * face's current size. If one is found, the function returns.
- * The bitmap data can be accessed from the glyph slot (see note
- * below).
- *
- * 2. If no embedded bitmap is searched or found, FreeType looks for a
- * scalable outline. If one is found, it is loaded from the font
- * file, scaled to device pixels, then `hinted' to the pixel grid
- * in order to optimize it. The outline data can be accessed from
- * the glyph slot (see note below).
- *
- * Note that by default, the glyph loader doesn't render outlines into
- * bitmaps. The following flags are used to modify this default
- * behaviour to more specific and useful cases.
- *
- * FT_LOAD_NO_SCALE ::
- * Don't scale the loaded outline glyph but keep it in font units.
- *
- * This flag implies @FT_LOAD_NO_HINTING and @FT_LOAD_NO_BITMAP, and
- * unsets @FT_LOAD_RENDER.
- *
- * If the font is `tricky' (see @FT_FACE_FLAG_TRICKY for more), using
- * FT_LOAD_NO_SCALE usually yields meaningless outlines because the
- * subglyphs must be scaled and positioned with hinting instructions.
- * This can be solved by loading the font without FT_LOAD_NO_SCALE and
- * setting the character size to `font->units_per_EM'.
- *
- * FT_LOAD_NO_HINTING ::
- * Disable hinting. This generally generates `blurrier' bitmap glyphs
- * when the glyph are rendered in any of the anti-aliased modes. See
- * also the note below.
- *
- * This flag is implied by @FT_LOAD_NO_SCALE.
- *
- * FT_LOAD_RENDER ::
- * Call @FT_Render_Glyph after the glyph is loaded. By default, the
- * glyph is rendered in @FT_RENDER_MODE_NORMAL mode. This can be
- * overridden by @FT_LOAD_TARGET_XXX or @FT_LOAD_MONOCHROME.
- *
- * This flag is unset by @FT_LOAD_NO_SCALE.
- *
- * FT_LOAD_NO_BITMAP ::
- * Ignore bitmap strikes when loading. Bitmap-only fonts ignore this
- * flag.
- *
- * @FT_LOAD_NO_SCALE always sets this flag.
- *
- * FT_LOAD_VERTICAL_LAYOUT ::
- * Load the glyph for vertical text layout. In particular, the
- * `advance' value in the @FT_GlyphSlotRec structure is set to the
- * `vertAdvance' value of the `metrics' field.
- *
- * In case @FT_HAS_VERTICAL doesn't return true, you shouldn't use
- * this flag currently. Reason is that in this case vertical metrics
- * get synthesized, and those values are not always consistent across
- * various font formats.
- *
- * FT_LOAD_FORCE_AUTOHINT ::
- * Indicates that the auto-hinter is preferred over the font's native
- * hinter. See also the note below.
- *
- * FT_LOAD_CROP_BITMAP ::
- * Indicates that the font driver should crop the loaded bitmap glyph
- * (i.e., remove all space around its black bits). Not all drivers
- * implement this.
- *
- * FT_LOAD_PEDANTIC ::
- * Indicates that the font driver should perform pedantic verifications
- * during glyph loading. This is mostly used to detect broken glyphs
- * in fonts. By default, FreeType tries to handle broken fonts also.
- *
- * In particular, errors from the TrueType bytecode engine are not
- * passed to the application if this flag is not set; this might
- * result in partially hinted or distorted glyphs in case a glyph's
- * bytecode is buggy.
- *
- * FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH ::
- * Ignored. Deprecated.
- *
- * FT_LOAD_NO_RECURSE ::
- * This flag is only used internally. It merely indicates that the
- * font driver should not load composite glyphs recursively. Instead,
- * it should set the `num_subglyph' and `subglyphs' values of the
- * glyph slot accordingly, and set `glyph->format' to
- * @FT_GLYPH_FORMAT_COMPOSITE.
- *
- * The description of sub-glyphs is not available to client
- * applications for now.
- *
- * This flag implies @FT_LOAD_NO_SCALE and @FT_LOAD_IGNORE_TRANSFORM.
- *
- * FT_LOAD_IGNORE_TRANSFORM ::
- * Indicates that the transform matrix set by @FT_Set_Transform should
- * be ignored.
- *
- * FT_LOAD_MONOCHROME ::
- * This flag is used with @FT_LOAD_RENDER to indicate that you want to
- * render an outline glyph to a 1-bit monochrome bitmap glyph, with
- * 8~pixels packed into each byte of the bitmap data.
- *
- * Note that this has no effect on the hinting algorithm used. You
- * should rather use @FT_LOAD_TARGET_MONO so that the
- * monochrome-optimized hinting algorithm is used.
- *
- * FT_LOAD_LINEAR_DESIGN ::
- * Indicates that the `linearHoriAdvance' and `linearVertAdvance'
- * fields of @FT_GlyphSlotRec should be kept in font units. See
- * @FT_GlyphSlotRec for details.
- *
- * FT_LOAD_NO_AUTOHINT ::
- * Disable auto-hinter. See also the note below.
- *
- * FT_LOAD_COLOR ::
- * This flag is used to request loading of color embedded-bitmap
- * images. The resulting color bitmaps, if available, will have the
- * @FT_PIXEL_MODE_BGRA format. When the flag is not used and color
- * bitmaps are found, they will be converted to 256-level gray
- * bitmaps transparently. Those bitmaps will be in the
- * @FT_PIXEL_MODE_GRAY format.
- *
- * @note:
- * By default, hinting is enabled and the font's native hinter (see
- * @FT_FACE_FLAG_HINTER) is preferred over the auto-hinter. You can
- * disable hinting by setting @FT_LOAD_NO_HINTING or change the
- * precedence by setting @FT_LOAD_FORCE_AUTOHINT. You can also set
- * @FT_LOAD_NO_AUTOHINT in case you don't want the auto-hinter to be
- * used at all.
- *
- * See the description of @FT_FACE_FLAG_TRICKY for a special exception
- * (affecting only a handful of Asian fonts).
- *
- * Besides deciding which hinter to use, you can also decide which
- * hinting algorithm to use. See @FT_LOAD_TARGET_XXX for details.
- *
- * Note that the auto-hinter needs a valid Unicode cmap (either a native
- * one or synthesized by FreeType) for producing correct results. If a
- * font provides an incorrect mapping (for example, assigning the
- * character code U+005A, LATIN CAPITAL LETTER Z, to a glyph depicting a
- * mathematical integral sign), the auto-hinter might produce useless
- * results.

- *
- * @enum:
- * FT_LOAD_TARGET_XXX
- *
- * @description:
- * A list of values that are used to select a specific hinting algorithm
- * to use by the hinter. You should OR one of these values to your
- * `load_flags' when calling @FT_Load_Glyph.
- *
- * Note that font's native hinters may ignore the hinting algorithm you
- * have specified (e.g., the TrueType bytecode interpreter). You can set
- * @FT_LOAD_FORCE_AUTOHINT to ensure that the auto-hinter is used.
- *
- * Also note that @FT_LOAD_TARGET_LIGHT is an exception, in that it
- * always implies @FT_LOAD_FORCE_AUTOHINT.
- *
- * @values:
- * FT_LOAD_TARGET_NORMAL ::
- * This corresponds to the default hinting algorithm, optimized for
- * standard gray-level rendering. For monochrome output, use
- * @FT_LOAD_TARGET_MONO instead.
- *
- * FT_LOAD_TARGET_LIGHT ::
- * A lighter hinting algorithm for non-monochrome modes. Many
- * generated glyphs are more fuzzy but better resemble its original
- * shape. A bit like rendering on Mac OS~X.
- *
- * As a special exception, this target implies @FT_LOAD_FORCE_AUTOHINT.
- *
- * FT_LOAD_TARGET_MONO ::
- * Strong hinting algorithm that should only be used for monochrome
- * output. The result is probably unpleasant if the glyph is rendered
- * in non-monochrome modes.
- *
- * FT_LOAD_TARGET_LCD ::
- * A variant of @FT_LOAD_TARGET_NORMAL optimized for horizontally
- * decimated LCD displays.
- *
- * FT_LOAD_TARGET_LCD_V ::
- * A variant of @FT_LOAD_TARGET_NORMAL optimized for vertically
- * decimated LCD displays.
- *
- * @note:
- * You should use only _one_ of the FT_LOAD_TARGET_XXX values in your
- * `load_flags'. They can't be ORed.
- *
- * If @FT_LOAD_RENDER is also set, the glyph is rendered in the
- * corresponding mode (i.e., the mode which matches the used algorithm
- * best). An exeption is FT_LOAD_TARGET_MONO since it implies
- * @FT_LOAD_MONOCHROME.
- *
- * You can use a hinting algorithm that doesn't correspond to the same
- * rendering mode. As an example, it is possible to use the `light'
- * hinting algorithm and have the results rendered in horizontal LCD
- * pixel mode, with code like
- *
- * {

In this case, the following happens: + * + * 1. FreeType looks for a bitmap for the glyph corresponding to the + * face's current size. If one is found, the function returns. + * The bitmap data can be accessed from the glyph slot (see note + * below). + * + * 2. If no embedded bitmap is searched or found, FreeType looks for a + * scalable outline. If one is found, it is loaded from the font + * file, scaled to device pixels, then `hinted' to the pixel grid + * in order to optimize it. The outline data can be accessed from + * the glyph slot (see note below). + * + * Note that by default, the glyph loader doesn't render outlines into + * bitmaps. The following flags are used to modify this default + * behaviour to more specific and useful cases. + * + * FT_LOAD_NO_SCALE :: + * Don't scale the loaded outline glyph but keep it in font units. + * + * This flag implies @FT_LOAD_NO_HINTING and @FT_LOAD_NO_BITMAP, and + * unsets @FT_LOAD_RENDER. + * + * If the font is `tricky' (see @FT_FACE_FLAG_TRICKY for more), using + * FT_LOAD_NO_SCALE usually yields meaningless outlines because the + * subglyphs must be scaled and positioned with hinting instructions. + * This can be solved by loading the font without FT_LOAD_NO_SCALE and + * setting the character size to `font->units_per_EM'. + * + * FT_LOAD_NO_HINTING :: + * Disable hinting. This generally generates `blurrier' bitmap glyphs + * when the glyph are rendered in any of the anti-aliased modes. See + * also the note below. + * + * This flag is implied by @FT_LOAD_NO_SCALE. + * + * FT_LOAD_RENDER :: + * Call @FT_Render_Glyph after the glyph is loaded. By default, the + * glyph is rendered in @FT_RENDER_MODE_NORMAL mode. This can be + * overridden by @FT_LOAD_TARGET_XXX or @FT_LOAD_MONOCHROME. + * + * This flag is unset by @FT_LOAD_NO_SCALE. + * + * FT_LOAD_NO_BITMAP :: + * Ignore bitmap strikes when loading. Bitmap-only fonts ignore this + * flag. + * + * @FT_LOAD_NO_SCALE always sets this flag. + * + * FT_LOAD_VERTICAL_LAYOUT :: + * Load the glyph for vertical text layout. In particular, the + * `advance' value in the @FT_GlyphSlotRec structure is set to the + * `vertAdvance' value of the `metrics' field. + * + * In case @FT_HAS_VERTICAL doesn't return true, you shouldn't use + * this flag currently. Reason is that in this case vertical metrics + * get synthesized, and those values are not always consistent across + * various font formats. + * + * FT_LOAD_FORCE_AUTOHINT :: + * Indicates that the auto-hinter is preferred over the font's native + * hinter. See also the note below. + * + * FT_LOAD_CROP_BITMAP :: + * Indicates that the font driver should crop the loaded bitmap glyph + * (i.e., remove all space around its black bits). Not all drivers + * implement this. + * + * FT_LOAD_PEDANTIC :: + * Indicates that the font driver should perform pedantic verifications + * during glyph loading. This is mostly used to detect broken glyphs + * in fonts. By default, FreeType tries to handle broken fonts also. + * + * In particular, errors from the TrueType bytecode engine are not + * passed to the application if this flag is not set; this might + * result in partially hinted or distorted glyphs in case a glyph's + * bytecode is buggy. + * + * FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH :: + * Ignored. Deprecated. + * + * FT_LOAD_NO_RECURSE :: + * This flag is only used internally. It merely indicates that the + * font driver should not load composite glyphs recursively. Instead, + * it should set the `num_subglyph' and `subglyphs' values of the + * glyph slot accordingly, and set `glyph->format' to + * @FT_GLYPH_FORMAT_COMPOSITE. + * + * The description of sub-glyphs is not available to client + * applications for now. + * + * This flag implies @FT_LOAD_NO_SCALE and @FT_LOAD_IGNORE_TRANSFORM. + * + * FT_LOAD_IGNORE_TRANSFORM :: + * Indicates that the transform matrix set by @FT_Set_Transform should + * be ignored. + * + * FT_LOAD_MONOCHROME :: + * This flag is used with @FT_LOAD_RENDER to indicate that you want to + * render an outline glyph to a 1-bit monochrome bitmap glyph, with + * 8~pixels packed into each byte of the bitmap data. + * + * Note that this has no effect on the hinting algorithm used. You + * should rather use @FT_LOAD_TARGET_MONO so that the + * monochrome-optimized hinting algorithm is used. + * + * FT_LOAD_LINEAR_DESIGN :: + * Indicates that the `linearHoriAdvance' and `linearVertAdvance' + * fields of @FT_GlyphSlotRec should be kept in font units. See + * @FT_GlyphSlotRec for details. + * + * FT_LOAD_NO_AUTOHINT :: + * Disable auto-hinter. See also the note below. + * + * FT_LOAD_COLOR :: + * This flag is used to request loading of color embedded-bitmap + * images. The resulting color bitmaps, if available, will have the + * @FT_PIXEL_MODE_BGRA format. When the flag is not used and color + * bitmaps are found, they will be converted to 256-level gray + * bitmaps transparently. Those bitmaps will be in the + * @FT_PIXEL_MODE_GRAY format. + * + * @note: + * By default, hinting is enabled and the font's native hinter (see + * @FT_FACE_FLAG_HINTER) is preferred over the auto-hinter. You can + * disable hinting by setting @FT_LOAD_NO_HINTING or change the + * precedence by setting @FT_LOAD_FORCE_AUTOHINT.

-/*
- The 'zlib' compression library provides in-memory compression and
- decompression functions, including integrity checks of the uncompressed data.
- This version of the library supports only one compression method (deflation)
- but other algorithms will be added later and will have the same stream
- interface.
-
- Compression can be done in a single step if the buffers are large enough,
- or can be done by repeated calls of the compression function. In the latter
- case, the application must provide more input and/or consume the output
- (providing more output space) before each call.
-
- The compressed data format used by default by the in-memory functions is
- the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
- around a deflate stream, which is itself documented in RFC 1951.
-
- The library also supports reading and writing files in gzip (.gz) format
- with an interface similar to that of stdio using the functions that start
- with "gz". The gzip format is different from the zlib format. gzip is a
- gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
-
- This library can optionally read and write gzip streams in memory as well.
-
- The zlib format was designed to be compact and fast for use in memory
- and on communications channels. The gzip format was designed for single-
- file compression on file systems, has a larger header than zlib to maintain
- directory information, and uses a different, slower check method than zlib.
-
- The library does not install any signal handler. The decoder checks
- the consistency of the compressed data, so the library should never crash
- even in case of corrupted input.

-ZEXTERN int ZEXPORT deflate OF((z_streamp strm, int flush));
-/*
- deflate compresses as much data as possible, and stops when the input
- buffer becomes empty or the output buffer becomes full. It may introduce
- some output latency (reading input without producing any output) except when
- forced to flush.
-
- The detailed semantics are as follows. deflate performs one or both of the
- following actions:
-
- - Compress more input starting at next_in and update next_in and avail_in
- accordingly. If not all input can be processed (because there is not
- enough room in the output buffer), next_in and avail_in are updated and
- processing will resume at this point for the next call of deflate().
-
- - Provide more output starting at next_out and update next_out and avail_out
- accordingly. This action is forced if the parameter flush is non zero.
- Forcing flush frequently degrades the compression ratio, so this parameter
- should be set only when necessary (in interactive applications). Some
- output may be provided even if flush is not set.
-
- Before the call of deflate(), the application should ensure that at least
- one of the actions is possible, by providing more input and/or consuming more
- output, and updating avail_in or avail_out accordingly; avail_out should
- never be zero before the call. The application can consume the compressed
- output when it wants, for example when the output buffer is full (avail_out
- == 0), or after each call of deflate(). If deflate returns Z_OK and with
- zero avail_out, it must be called again after making room in the output
- buffer because there might be more output pending.
-
- Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
- decide how much data to accumulate before producing output, in order to
- maximize compression.
-
- If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
- flushed to the output buffer and the output is aligned on a byte boundary, so
- that the decompressor can get all input data available so far. (In
- particular avail_in is zero after the call if enough output space has been
- provided before the call.) Flushing may degrade compression for some
- compression algorithms and so it should be used only when necessary. This
- completes the current deflate block and follows it with an empty stored block
- that is three bits plus filler bits to the next byte, followed by four bytes
- (00 00 ff ff).
-
- If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
- output buffer, but the output is not aligned to a byte boundary. All of the
- input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
- This completes the current deflate block and follows it with an empty fixed
- codes block that is 10 bits long. This assures that enough bytes are output
- in order for the decompressor to finish the block before the empty fixed code
- block.
-
- If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
- for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
- seven bits of the current block are held to be written as the next byte after
- the next deflate block is completed. In this case, the decompressor may not
- be provided enough bits at this point in order to complete decompression of
- the data provided so far to the compressor. It may need to wait for the next
- block to be emitted. This is for advanced applications that need to control
- the emission of deflate blocks.
-
- If flush is set to Z_FULL_FLUSH, all output is flushed as with
- Z_SYNC_FLUSH, and the compression state is reset so that decompression can
- restart from this point if previous compressed data has been damaged or if
- random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
- compression.
-
- If deflate returns with avail_out == 0, this function must be called again
- with the same value of the flush parameter and more output space (updated
- avail_out), until the flush is complete (deflate returns with non-zero
- avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
- avail_out is greater than six to avoid repeated flush markers due to
- avail_out == 0 on return.
-
- If the parameter flush is set to Z_FINISH, pending input is processed,
- pending output is flushed and deflate returns with Z_STREAM_END if there was
- enough output space; if deflate returns with Z_OK, this function must be
- called again with Z_FINISH and more output space (updated avail_out) but no
- more input data, until it returns with Z_STREAM_END or an error. After
- deflate has returned Z_STREAM_END, the only possible operations on the stream
- are deflateReset or deflateEnd.
-
- Z_FINISH can be used immediately after deflateInit if all the compression
- is to be done in a single step. In this case, avail_out must be at least the
- value returned by deflateBound (see below). Then deflate is guaranteed to
- return Z_STREAM_END. If not enough output space is provided, deflate will
- not return Z_STREAM_END, and it must be called again as described above.
-
- deflate() sets strm->adler to the adler32 checksum of all input read
- so far (that is, total_in bytes).
-
- deflate() may update strm->data_type if it can make a good guess about
- the input data type (Z_BINARY or Z_TEXT). In doubt, the data is considered
- binary. This field is only for information purposes and does not affect the
- compression algorithm in any manner.
-
- deflate() returns Z_OK if some progress has been made (more input
- processed or more output produced), Z_STREAM_END if all input has been
- consumed and all output has been produced (only when flush is set to
- Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
- if next_in or next_out was Z_NULL), Z_BUF_ERROR if no progress is possible
- (for example avail_in or avail_out was zero). Note that Z_BUF_ERROR is not
- fatal, and deflate() can be called again with more input and more output

- - Provide more output starting at next_out and update next_out and avail_out
- accordingly. inflate() provides as much output as possible, until there is
- no more input data or no more space in the output buffer (see below about
- the flush parameter).
-
- Before the call of inflate(), the application should ensure that at least
- one of the actions is possible, by providing more input and/or consuming more
- output, and updating the next_* and avail_* values accordingly. The
- application can consume the uncompressed output when it wants, for example
- when the output buffer is full (avail_out == 0), or after each call of
- inflate(). If inflate returns Z_OK and with zero avail_out, it must be
- called again after making room in the output buffer because there might be
- more output pending.
-
- The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
- Z_BLOCK, or Z_TREES. Z_SYNC_FLUSH requests that inflate() flush as much
- output as possible to the output buffer. Z_BLOCK requests that inflate()
- stop if and when it gets to the next deflate block boundary. When decoding
- the zlib or gzip format, this will cause inflate() to return immediately
- after the header and before the first block. When doing a raw inflate,
- inflate() will go ahead and process the first block, and will return when it
- gets to the end of that block, or when it runs out of data.
-
- The Z_BLOCK option assists in appending to or combining deflate streams.
- Also to assist in this, on return inflate() will set strm->data_type to the
- number of unused bits in the last byte taken from strm->next_in, plus 64 if
- inflate() is currently decoding the last block in the deflate stream, plus
- 128 if inflate() returned immediately after decoding an end-of-block code or
- decoding the complete header up to just before the first byte of the deflate
- stream. The end-of-block will not be indicated until all of the uncompressed
- data from that block has been written to strm->next_out. The number of
- unused bits may in general be greater than seven, except when bit 7 of
- data_type is set, in which case the number of unused bits will be less than
- eight. data_type is set as noted here every time inflate() returns for all
- flush options, and so can be used to determine the amount of currently
- consumed input in bits.
-
- The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
- end of each deflate block header is reached, before any actual data in that
- block is decoded. This allows the caller to determine the length of the
- deflate block header for later use in random access within a deflate block.
- 256 is added to the value of strm->data_type when inflate() returns
- immediately after reaching the end of the deflate block header.
-
- inflate() should normally be called until it returns Z_STREAM_END or an
- error. However if all decompression is to be performed in a single step (a
- single call of inflate), the parameter flush should be set to Z_FINISH. In
- this case all pending input is processed and all pending output is flushed;
- avail_out must be large enough to hold all of the uncompressed data for the
- operation to complete. (The size of the uncompressed data may have been
- saved by the compressor for this purpose.) The use of Z_FINISH is not
- required to perform an inflation in one step. However it may be used to
- inform inflate that a faster approach can be used for the single inflate()
- call. Z_FINISH also informs inflate to not maintain a sliding window if the
- stream completes, which reduces inflate's memory footprint. If the stream
- does not complete, either because not all of the stream is provided or not
- enough output space is provided, then a sliding window will be allocated and
- inflate() can be called again to continue the operation as if Z_NO_FLUSH had
- been used.
-
- In this implementation, inflate() always flushes as much output as
- possible to the output buffer, and always uses the faster approach on the
- first call. So the effects of the flush parameter in this implementation are
- on the return value of inflate() as noted below, when inflate() returns early
- when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
- memory for a sliding window when Z_FINISH is used.
-
- If a preset dictionary is needed after this call (see inflateSetDictionary
- below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
- chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
- strm->adler to the Adler-32 checksum of all output produced so far (that is,
- total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
- below. At the end of the stream, inflate() checks that its computed adler32
- checksum is equal to that saved by the compressor and returns Z_STREAM_END
- only if the checksum is correct.
-
- inflate() can decompress and check either zlib-wrapped or gzip-wrapped
- deflate data. The header type is detected automatically, if requested when
- initializing with inflateInit2(). Any information contained in the gzip
- header is not retained, so applications that need that information should
- instead use raw inflate, see inflateInit2() below, or inflateBack() and
- perform their own processing of the gzip header and trailer. When processing
- gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
- producted so far. The CRC-32 is checked against the gzip trailer.
-
- inflate() returns Z_OK if some progress has been made (more input processed
- or more output produced), Z_STREAM_END if the end of the compressed data has
- been reached and all uncompressed output has been produced, Z_NEED_DICT if a
- preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
- corrupted (input stream not conforming to the zlib format or incorrect check
- value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
- next_in or next_out was Z_NULL), Z_MEM_ERROR if there was not enough memory,
- Z_BUF_ERROR if no progress is possible or if there was not enough room in the
- output buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and
- inflate() can be called again with more input and more output space to
- continue decompressing. If Z_DATA_ERROR is returned, the application may
- then call inflateSync() to look for a good compression block if a partial
- recovery of the data is desired.

- This is another version of deflateInit with more compression options. The

-
- The method parameter is the compression method. It must be Z_DEFLATED in

-
- The windowBits parameter is the base two logarithm of the window size
- (the size of the history buffer). It should be in the range 8..15 for this
- version of the library. Larger values of this parameter result in better
- compression at the expense of memory usage. The default value is 15 if
- deflateInit is used instead.
-
- windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
- determines the window size. deflate() will then generate raw deflate data
- with no zlib header or trailer, and will not compute an adler32 check value.
-
- windowBits can also be greater than 15 for optional gzip encoding. Add
- 16 to windowBits to write a simple gzip header and trailer around the
- compressed data instead of a zlib wrapper. The gzip header will have no
- file name, no extra data, no comment, no modification time (set to zero), no
- header crc, and the operating system will be set to 255 (unknown). If a
- gzip stream is being written, strm->adler is a crc32 instead of an adler32.
-
- The memLevel parameter specifies how much memory should be allocated

- slow and reduces compression ratio; memLevel=9 uses maximum memory for
- optimal speed. The default value is 8. See zconf.h for total memory usage
- as a function of windowBits and memLevel.
-
- The strategy parameter is used to tune the compression algorithm. Use the
- value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
- filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
- string match), or Z_RLE to limit match distances to one (run-length
- encoding). Filtered data consists mostly of small values with a somewhat
- random distribution. In this case, the compression algorithm is tuned to
- compress them better. The effect of Z_FILTERED is to force more Huffman
- coding and less string matching; it is somewhat intermediate between
- Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as
- fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data. The
- strategy parameter only affects the compression ratio but not the
- correctness of the compressed output even if it is not set appropriately.
- Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
- decoder for special applications.

- buffer. inflate() can be faster on modern CPUs when used with large
- buffers. inflateBack() trusts the application to not change the output
- buffer passed by the output function, at least until inflateBack() returns.
-
- inflateBackInit() must be called first to allocate the internal state
- and to initialize the state with the user-provided window buffer.
- inflateBack() may then be used multiple times to inflate a complete, raw
- deflate stream with each call. inflateBackEnd() is then called to free the
- allocated state.
-
- A raw deflate stream is one with no zlib or gzip header or trailer.
- This routine would normally be used in a utility that reads zip or gzip
- files and writes out uncompressed files. The utility would decode the
- header and process the trailer on its own, hence this routine expects only
- the raw deflate stream to decompress. This is different from the normal
- behavior of inflate(), which expects either a zlib or gzip header and
- trailer around the deflate stream.
-
- inflateBack() uses two subroutines supplied by the caller that are then
- called by inflateBack() for input and output. inflateBack() calls those
- routines until it reads a complete deflate stream and writes out all of the
- uncompressed data, or until it encounters an error. The function's
- parameters and return types are defined above in the in_func and out_func
- typedefs. inflateBack() will call in(in_desc, &buf) which should return the
- number of bytes of provided input, and a pointer to that input in buf. If
- there is no input available, in() must return zero--buf is ignored in that
- case--and inflateBack() will return a buffer error. inflateBack() will call
- out(out_desc, buf, len) to write the uncompressed data buf[0..len-1]. out()
- should return zero on success, or non-zero on failure. If out() returns
- non-zero, inflateBack() will return with an error. Neither in() nor out()
- are permitted to change the contents of the window provided to
- inflateBackInit(), which is also the buffer that out() uses to write from.
- The length written by out() will be at most the window size. Any non-zero
- amount of input may be provided by in().
-
- For convenience, inflateBack() can be provided input on the first call by
- setting strm->next_in and strm->avail_in. If that input is exhausted, then
- in() will be called. Therefore strm->next_in must be initialized before
- calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called
- immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in
- must also be initialized, and then if strm->avail_in is not zero, input will
- initially be taken from strm->next_in[0 .. strm->avail_in - 1].
-
- The in_desc and out_desc parameters of inflateBack() is passed as the
- first parameter of in() and out() respectively when they are called. These
- descriptors can be optionally used to pass any information that the caller-
- supplied in() and out() functions need to do their job.
-
- On return, inflateBack() will set strm->next_in and strm->avail_in to
- pass back any unused input that was provided by the last in() call. The
- return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
- if in() or out() returned an error, Z_DATA_ERROR if there was a format error
- in the deflate stream (in which case strm->msg is set to indicate the nature
- of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
- In the case of Z_BUF_ERROR, an input or output error can be distinguished
- using strm->next_in which will be Z_NULL only if in() returned an error. If
- strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
- non-zero. (in() will always be called before out(), so strm->next_in is
- assured to be defined if out() returns non-zero.) Note that inflateBack()

- in fopen ("rb" or "wb") but can also include a compression level ("wb9") or
- a strategy: 'f' for filtered data as in "wb6f", 'h' for Huffman-only
- compression as in "wb1h", 'R' for run-length encoding as in "wb1R", or 'F'
- for fixed code compression as in "wb9F". (See the description of
- deflateInit2 for more information about the strategy parameter.) 'T' will
- request transparent writing or appending with no compression and not using
- the gzip format.
-
- "a" can be used instead of "w" to request that the gzip stream that will
- be written be appended to the file. "+" will result in an error, since
- reading and writing to the same gzip file is not supported. The addition of
- "x" when writing will create the file exclusively, which fails if the file
- already exists. On systems that support it, the addition of "e" when
- reading or writing will set the flag to close the file on an execve() call.
-
- These functions, as well as gzip, will read and decode a sequence of gzip
- streams in a file. The append function of gzopen() can be used to create
- such a file. (Also see gzflush() for another way to do this.) When
- appending, gzopen does not test whether the file begins with a gzip stream,
- nor does it look for the end of the gzip streams to begin appending. gzopen
- will simply append a gzip stream to the existing file.
-
- gzopen can be used to read a file which is not in gzip format; in this
- case gzread will directly read from the file without decompression. When
- reading, this will be detected automatically by looking for the magic two-
- byte gzip header.
-
- gzopen returns NULL if the file could not be opened, if there was
- insufficient memory to allocate the gzFile state, or if an invalid mode was

This action is forced if the parameter flush is non zero. + Forcing flush frequently degrades the compression ratio, so this parameter + should be set only when necessary (in interactive applications).

The application can consume the compressed + output when it wants, for example when the output buffer is full (avail_out + == 0), or after each call of deflate(). If deflate returns Z_OK and with + zero avail_out, it must be called again after making room in the output + buffer because there might be more output pending. + + Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to + decide how much data to accumulate before producing output, in order to + maximize compression. + + If the parameter flush is set to Z_SYNC_FLUSH, all pending output is + flushed to the output buffer and the output is aligned on a byte boundary, so + that the decompressor can get all input data available so far. (In + particular avail_in is zero after the call if enough output space has been + provided before the call.) Flushing may degrade compression for some + compression algorithms and so it should be used only when necessary. This + completes the current deflate block and follows it with an empty stored block + that is three bits plus filler bits to the next byte, followed by four bytes + (00 00 ff ff). + + If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the + output buffer, but the output is not aligned to a byte boundary. All of the + input data so far will be available to the decompressor, as for Z_SYNC_FLUSH. + This completes the current deflate block and follows it with an empty fixed + codes block that is 10 bits long. This assures that enough bytes are output + in order for the decompressor to finish the block before the empty fixed code + block. + + If flush is set to Z_BLOCK, a deflate block is completed and emitted, as + for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to + seven bits of the current block are held to be written as the next byte after + the next deflate block is completed. In this case, the decompressor may not + be provided enough bits at this point in order to complete decompression of + the data provided so far to the compressor. It may need to wait for the next + block to be emitted. This is for advanced applications that need to control + the emission of deflate blocks. + + If flush is set to Z_FULL_FLUSH, all output is flushed as with + Z_SYNC_FLUSH, and the compression state is reset so that decompression can + restart from this point if previous compressed data has been damaged or if + random access is desired. Using Z_FULL_FLUSH too often can seriously degrade + compression. + + If deflate returns with avail_out == 0, this function must be called again + with the same value of the flush parameter and more output space (updated + avail_out), until the flush is complete (deflate returns with non-zero + avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that + avail_out is greater than six to avoid repeated flush markers due to + avail_out == 0 on return. + + If the parameter flush is set to Z_FINISH, pending input is processed, + pending output is flushed and deflate returns with Z_STREAM_END if there was + enough output space; if deflate returns with Z_OK, this function must be + called again with Z_FINISH and more output space (updated avail_out) but no + more input data, until it returns with Z_STREAM_END or an error. After + deflate has returned Z_STREAM_END, the only possible operations on the stream + are deflateReset or deflateEnd. + + Z_FINISH can be used immediately after deflateInit if all the compression + is to be done in a single step.

The + application can consume the uncompressed output when it wants, for example + when the output buffer is full (avail_out == 0), or after each call of + inflate(). If inflate returns Z_OK and with zero avail_out, it must be + called again after making room in the output buffer because there might be + more output pending. + + The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH, + Z_BLOCK, or Z_TREES. Z_SYNC_FLUSH requests that inflate() flush as much + output as possible to the output buffer. Z_BLOCK requests that inflate() + stop if and when it gets to the next deflate block boundary. When decoding + the zlib or gzip format, this will cause inflate() to return immediately + after the header and before the first block. When doing a raw inflate, + inflate() will go ahead and process the first block, and will return when it + gets to the end of that block, or when it runs out of data. + + The Z_BLOCK option assists in appending to or combining deflate streams. + Also to assist in this, on return inflate() will set strm->data_type to the + number of unused bits in the last byte taken from strm->next_in, plus 64 if + inflate() is currently decoding the last block in the deflate stream, plus + 128 if inflate() returned immediately after decoding an end-of-block code or + decoding the complete header up to just before the first byte of the deflate + stream. The end-of-block will not be indicated until all of the uncompressed + data from that block has been written to strm->next_out. The number of + unused bits may in general be greater than seven, except when bit 7 of + data_type is set, in which case the number of unused bits will be less than + eight. data_type is set as noted here every time inflate() returns for all + flush options, and so can be used to determine the amount of currently + consumed input in bits. + + The Z_TREES option behaves as Z_BLOCK does, but it also returns when the + end of each deflate block header is reached, before any actual data in that + block is decoded. This allows the caller to determine the length of the + deflate block header for later use in random access within a deflate block. + 256 is added to the value of strm->data_type when inflate() returns + immediately after reaching the end of the deflate block header. + + inflate() should normally be called until it returns Z_STREAM_END or an + error. However if all decompression is to be performed in a single step (a + single call of inflate), the parameter flush should be set to Z_FINISH. In + this case all pending input is processed and all pending output is flushed; + avail_out must be large enough to hold all of the uncompressed data for the + operation to complete. (The size of the uncompressed data may have been + saved by the compressor for this purpose.) The use of Z_FINISH is not + required to perform an inflation in one step. However it may be used to + inform inflate that a faster approach can be used for the single inflate() + call. Z_FINISH also informs inflate to not maintain a sliding window if the + stream completes, which reduces inflate's memory footprint. If the stream + does not complete, either because not all of the stream is provided or not + enough output space is provided, then a sliding window will be allocated and + inflate() can be called again to continue the operation as if Z_NO_FLUSH had + been used. + + In this implementation, inflate() always flushes as much output as + possible to the output buffer, and always uses the faster approach on the + first call. So the effects of the flush parameter in this implementation are + on the return value of inflate() as noted below, when inflate() returns early + when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of + memory for a sliding window when Z_FINISH is used. + + If a preset dictionary is needed after this call (see inflateSetDictionary + below), inflate sets strm->adler to the Adler-32 checksum of the dictionary + chosen by the compressor and returns Z_NEED_DICT; otherwise it sets + strm->adler to the Adler-32 checksum of all output produced so far (that is, + total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described + below. At the end of the stream, inflate() checks that its computed adler32 + checksum is equal to that saved by the compressor and returns Z_STREAM_END + only if the checksum is correct. + + inflate() can decompress and check either zlib-wrapped or gzip-wrapped + deflate data. The header type is detected automatically, if requested when + initializing with inflateInit2(). Any information contained in the gzip + header is not retained, so applications that need that information should + instead use raw inflate, see inflateInit2() below, or inflateBack() and + perform their own processing of the gzip header and trailer.
