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. + * + */ +#define FT_LOAD_DEFAULT 0x0 +#define FT_LOAD_NO_SCALE ( 1L << 0 ) +#define FT_LOAD_NO_HINTING ( 1L << 1 ) +#define FT_LOAD_RENDER ( 1L << 2 ) +#define FT_LOAD_NO_BITMAP ( 1L << 3 ) +#define FT_LOAD_VERTICAL_LAYOUT ( 1L << 4 ) +#define FT_LOAD_FORCE_AUTOHINT ( 1L << 5 ) +#define FT_LOAD_CROP_BITMAP ( 1L << 6 ) +#define FT_LOAD_PEDANTIC ( 1L << 7 ) +#define FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH ( 1L << 9 ) +#define FT_LOAD_NO_RECURSE ( 1L << 10 ) +#define FT_LOAD_IGNORE_TRANSFORM ( 1L << 11 ) +#define FT_LOAD_MONOCHROME ( 1L << 12 ) +#define FT_LOAD_LINEAR_DESIGN ( 1L << 13 ) +#define FT_LOAD_NO_AUTOHINT ( 1L << 15 ) + /* Bits 16..19 are used by `FT_LOAD_TARGET_' */ +#define FT_LOAD_COLOR ( 1L << 20 ) + + /* */ + + /* used internally only by certain font drivers! */ +#define FT_LOAD_ADVANCE_ONLY ( 1L << 8 ) +#define FT_LOAD_SBITS_ONLY ( 1L << 14 ) + + + /************************************************************************** + * + * @enum: + * FT_LOAD_TARGET_XXX + * + * @description: + * A list of values that are used to select a specific hinting algorithm + * to use by the hinter.

This implies + * the following scheme: + * + * First, available or installed font faces are uniquely identified by + * @FTC_FaceID values, provided to the cache by the client. Note that + * the cache only stores and compares these values, and doesn't try to + * interpret them in any way. + * + * Second, the cache calls, only when needed, a client-provided function + * to convert an @FTC_FaceID into a new @FT_Face object. The latter is + * then completely managed by the cache, including its termination + * through @FT_Done_Face. To monitor termination of face objects, the + * finalizer callback in the `generic' field of the @FT_Face object can + * be used, which might also be used to store the @FTC_FaceID of the + * face. + * + * Clients are free to map face IDs to anything else. The most simple + * usage is to associate them to a (pathname,face_index) pair that is + * used to call @FT_New_Face. However, more complex schemes are also + * possible. + * + * Note that for the cache to work correctly, the face ID values must be + * *persistent*, which means that the contents they point to should not + * change at runtime, or that their value should not become invalid. + * + * If this is unavoidable (e.g., when a font is uninstalled at runtime), + * you should call @FTC_Manager_RemoveFaceID as soon as possible, to let + * the cache get rid of any references to the old @FTC_FaceID it may + * keep internally. Failure to do so will lead to incorrect behaviour + * or even crashes. + * + * To use the cache, start with calling @FTC_Manager_New to create a new + * @FTC_Manager object, which models a single cache instance. You can + * then look up @FT_Face and @FT_Size objects with + * @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively. + * + * If you want to use the charmap caching, call @FTC_CMapCache_New, then + * later use @FTC_CMapCache_Lookup to perform the equivalent of + * @FT_Get_Char_Index, only much faster. + * + * If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then + * later use @FTC_ImageCache_Lookup to retrieve the corresponding + * @FT_Glyph objects from the cache. + * + * If you need lots of small bitmaps, it is much more memory efficient + * to call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup. This + * returns @FTC_SBitRec structures, which are used to store small + * bitmaps directly.

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. 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.

The default value is 15 if + deflateInit is used instead. + + windowBits can also be -8..-15 for raw deflate.
