+
+/*
+ * TIFF Library.
+ * LogLuv compression support for high dynamic range images.
+ *
+ * Contributed by Greg Larson.
+ *
+ * LogLuv image support uses the TIFF library to store 16 or 10-bit
+ * log luminance values with 8 bits each of u and v or a 14-bit index.
+ *
+ * The codec can take as input and produce as output 32-bit IEEE float values 
+ * as well as 16-bit integer values.  A 16-bit luminance is interpreted
+ * as a sign bit followed by a 15-bit integer that is converted
+ * to and from a linear magnitude using the transformation:
+ *
+ *	L = 2^( (Le+.5)/256 - 64 )		# real from 15-bit
+ *
+ *	Le = floor( 256*(log2(L) + 64) )	# 15-bit from real
+ *
+ * The actual conversion to world luminance units in candelas per sq. meter
+ * requires an additional multiplier, which is stored in the TIFFTAG_STONITS.
+ * This value is usually set such that a reasonable exposure comes from
+ * clamping decoded luminances above 1 to 1 in the displayed image.
+ *
+ * The 16-bit values for u and v may be converted to real values by dividing
+ * each by 32768.  (This allows for negative values, which aren't useful as
+ * far as we know, but are left in case of future improvements in human
+ * color vision.)
+ *
+ * Conversion from (u,v), which is actually the CIE (u',v') system for
+ * you color scientists, is accomplished by the following transformation:
+ *
+ *	u = 4*x / (-2*x + 12*y + 3)
+ *	v = 9*y / (-2*x + 12*y + 3)
+ *
+ *	x = 9*u / (6*u - 16*v + 12)
+ *	y = 4*v / (6*u - 16*v + 12)
+ *
+ * This process is greatly simplified by passing 32-bit IEEE floats
+ * for each of three CIE XYZ coordinates.  The codec then takes care
+ * of conversion to and from LogLuv, though the application is still
+ * responsible for interpreting the TIFFTAG_STONITS calibration factor.
+ *
+ * By definition, a CIE XYZ vector of [1 1 1] corresponds to a neutral white
+ * point of (x,y)=(1/3,1/3).  However, most color systems assume some other
+ * white point, such as D65, and an absolute color conversion to XYZ then
+ * to another color space with a different white point may introduce an
+ * unwanted color cast to the image.  It is often desirable, therefore, to
+ * perform a white point conversion that maps the input white to [1 1 1]
+ * in XYZ, then record the original white point using the TIFFTAG_WHITEPOINT
+ * tag value.  A decoder that demands absolute color calibration may use
+ * this white point tag to get back the original colors, but usually it
+ * will be ignored and the new white point will be used instead that
+ * matches the output color space.
+ *
+ * Pixel information is compressed into one of two basic encodings, depending
+ * on the setting of the compression tag, which is one of COMPRESSION_SGILOG
+ * or COMPRESSION_SGILOG24.  For COMPRESSION_SGILOG, greyscale data is
+ * stored as:
+ *
+ *	 1       15
+ *	|-+---------------|
+ *
+ * COMPRESSION_SGILOG color data is stored as:
+ *
+ *	 1       15           8        8
+ *	|-+---------------|--------+--------|
+ *	 S       Le           ue       ve
+ *
+ * For the 24-bit COMPRESSION_SGILOG24 color format, the data is stored as:
+ *
+ *	     10           14
+ *	|----------|--------------|
+ *	     Le'          Ce
+ *
+ * There is no sign bit in the 24-bit case, and the (u,v) chromaticity is
+ * encoded as an index for optimal color resolution.  The 10 log bits are
+ * defined by the following conversions:
+ *
+ *	L = 2^((Le'+.5)/64 - 12)		# real from 10-bit
+ *
+ *	Le' = floor( 64*(log2(L) + 12) )	# 10-bit from real
+ *
+ * The 10 bits of the smaller format may be converted into the 15 bits of
+ * the larger format by multiplying by 4 and adding 13314.  Obviously,
+ * a smaller range of magnitudes is covered (about 5 orders of magnitude
+ * instead of 38), and the lack of a sign bit means that negative luminances
+ * are not allowed.  (Well, they aren't allowed in the real world, either,
+ * but they are useful for certain types of image processing.)
+ *
+ * The desired user format is controlled by the setting the internal
+ * pseudo tag TIFFTAG_SGILOGDATAFMT to one of:
+ *  SGILOGDATAFMT_FLOAT       = IEEE 32-bit float XYZ values
+ *  SGILOGDATAFMT_16BIT	      = 16-bit integer encodings of logL, u and v
+ * Raw data i/o is also possible using:
+ *  SGILOGDATAFMT_RAW         = 32-bit unsigned integer with encoded pixel
+ * In addition, the following decoding is provided for ease of display:
+ *  SGILOGDATAFMT_8BIT        = 8-bit default RGB gamma-corrected values
+ *
+ * For grayscale images, we provide the following data formats:
+ *  SGILOGDATAFMT_FLOAT       = IEEE 32-bit float Y values
+ *  SGILOGDATAFMT_16BIT       = 16-bit integer w/ encoded luminance
+ *  SGILOGDATAFMT_8BIT        = 8-bit gray monitor values
+ *
+ * Note that the COMPRESSION_SGILOG applies a simple run-length encoding
+ * scheme by separating the logL, u and v bytes for each row and applying
+ * a PackBits type of compression.  Since the 24-bit encoding is not
+ * adaptive, the 32-bit color format takes less space in many cases.
+ *
+ * Further control is provided over the conversion from higher-resolution
+ * formats to final encoded values through the pseudo tag
+ * TIFFTAG_SGILOGENCODE:
+ *  SGILOGENCODE_NODITHER     = do not dither encoded values
+ *  SGILOGENCODE_RANDITHER    = apply random dithering during encoding
+ *
+ * The default value of this tag is SGILOGENCODE_NODITHER for
+ * COMPRESSION_SGILOG to maximize run-length encoding and
+ * SGILOGENCODE_RANDITHER for COMPRESSION_SGILOG24 to turn
+ * quantization errors into noise.

+/* What is what, and what is not?
+
+   This decoder starts with an input stream, that is essentially the JpegInterchangeFormat
+   stream, if any, followed by the strile data, if any. This stream is read in
+   OJPEGReadByte and related functions.
+
+   It analyzes the start of this stream, until it encounters non-marker data, i.e.
+   compressed image data. Some of the header markers it sees have no actual content,
+   like the SOI marker, and APP/COM markers that really shouldn't even be there. Some
+   other markers do have content, and the valuable bits and pieces of information
+   in these markers are saved, checking all to verify that the stream is more or
+   less within expected bounds. This happens inside the OJPEGReadHeaderInfoSecStreamXxx
+   functions.
+
+   Some OJPEG imagery contains no valid JPEG header markers. This situation is picked
+   up on if we've seen no SOF marker when we're at the start of the compressed image
+   data. In this case, the tables are read from JpegXxxTables tags, and the other
+   bits and pieces of information is initialized to its most basic value. This is
+   implemented in the OJPEGReadHeaderInfoSecTablesXxx functions.
+
+   When this is complete, a good and valid JPEG header can be assembled, and this is
+   passed through to LibJpeg. When that's done, the remainder of the input stream, i.e.
+   the compressed image data, can be passed through unchanged. This is done in
+   OJPEGWriteStream functions.
+
+   LibTiff rightly expects to know the subsampling values before decompression. Just like
+   in new-style JPEG-in-TIFF, though, or even more so, actually, the YCbCrsubsampling
+   tag is notoriously unreliable. To correct these tag values with the ones inside
+   the JPEG stream, the first part of the input stream is pre-scanned in
+   OJPEGSubsamplingCorrect, making no note of any other data, reporting no warnings
+   or errors, up to the point where either these values are read, or it's clear they
+   aren't there. This means that some of the data is read twice, but we feel speed
+   in correcting these values is important enough to warrant this sacrifice. Allthough
+   there is currently no define or other configuration mechanism to disable this behaviour,
+   the actual header scanning is build to robustly respond with error report if it
+   should encounter an uncorrected mismatch of subsampling values. See
+   OJPEGReadHeaderInfoSecStreamSof.
+
+   The restart interval and restart markers are the most tricky part... The restart
+   interval can be specified in a tag. It can also be set inside the input JPEG stream.
+   It can be used inside the input JPEG stream. If reading from strile data, we've
+   consistenly discovered the need to insert restart markers in between the different
+   striles, as is also probably the most likely interpretation of the original TIFF 6.0
+   specification. With all this setting of interval, and actual use of markers that is not
+   predictable at the time of valid JPEG header assembly, the restart thing may turn
+   out the Achilles heel of this implementation. Fortunately, most OJPEG writer vendors
+   succeed in reading back what they write, which may be the reason why we've been able
+   to discover ways that seem to work.
+
+   Some special provision is made for planarconfig separate OJPEG files. These seem
+   to consistently contain header info, a SOS marker, a plane, SOS marker, plane, SOS,
+   and plane. This may or may not be a valid JPEG configuration, we don't know and don't
+   care. We want LibTiff to be able to access the planes individually, without huge
+   buffering inside LibJpeg, anyway. So we compose headers to feed to LibJpeg, in this
+   case, that allow us to pass a single plane such that LibJpeg sees a valid
+   single-channel JPEG stream. Locating subsequent SOS markers, and thus subsequent
+   planes, is done inside OJPEGReadSecondarySos.
+
+   The benefit of the scheme is... that it works, basically. We know of no other that
+   does. It works without checking software tag, or otherwise going about things in an
+   OJPEG flavor specific manner. Instead, it is a single scheme, that covers the cases
+   with and without JpegInterchangeFormat, with and without striles, with part of
+   the header in JpegInterchangeFormat and remainder in first strile, etc. It is forgiving
+   and robust, may likely work with OJPEG flavors we've not seen yet, and makes most out
+   of the data.
+
+   Another nice side-effect is that a complete JPEG single valid stream is build if
+   planarconfig is not separate (vast majority). We may one day use that to build
+   converters to JPEG, and/or to new-style JPEG compression inside TIFF.
+
+   A dissadvantage is the lack of random access to the individual striles. This is the
+   reason for much of the complicated restart-and-position stuff inside OJPEGPreDecode.
+   Applications would do well accessing all striles in order, as this will result in
+   a single sequential scan of the input stream, and no restarting of LibJpeg decoding
+   session.

+ * 	to fiddle with these if you define JPEG_ENCAP_EXTERNAL.

+ * 	instant processing, optimal streaming and optimal use of processor cache, but also big
+ * 	enough so as to not result in significant call overhead. It should be at least a few

+	 * TIFF but only supports some braindead idea of what the
+	 * vendor thinks TIFF is):
+	 *
+	 * 'l' use little-endian byte order for creating a file
+	 * 'b' use big-endian byte order for creating a file
+	 * 'L' read/write information using LSB2MSB bit order
+	 * 'B' read/write information using MSB2LSB bit order
+	 * 'H' read/write information using host bit order
+	 * 'M' enable use of memory-mapped files when supported
+	 * 'm' disable use of memory-mapped files
+	 * 'C' enable strip chopping support when reading
+	 * 'c' disable strip chopping support
+	 * 'h' read TIFF header only, do not load the first IFD
+	 * '4' ClassicTIFF for creating a file (default)
+	 * '8' BigTIFF for creating a file
+	 *
+	 * The use of the 'l' and 'b' flags is strongly discouraged.
+	 * These flags are provided solely because numerous vendors,
+	 * typically on the PC, do not correctly support TIFF; they
+	 * only support the Intel little-endian byte order.  This
+	 * support is not configured by default because it supports
+	 * the violation of the TIFF spec that says that readers *MUST*
+	 * support both byte orders.  It is strongly recommended that
+	 * you not use this feature except to deal with busted apps
+	 * that write invalid TIFF.  And even in those cases you should
+	 * bang on the vendors to fix their software.
+	 *
+	 * The 'L', 'B', and 'H' flags are intended for applications
+	 * that can optimize operations on data by using a particular
+	 * bit order.  By default the library returns data in MSB2LSB
+	 * bit order for compatibiltiy with older versions of this
+	 * library.  Returning data in the bit order of the native cpu
+	 * makes the most sense but also requires applications to check
+	 * the value of the FillOrder tag; something they probably do
+	 * not do right now.
+	 *
+	 * The 'M' and 'm' flags are provided because some virtual memory
+	 * systems exhibit poor behaviour when large images are mapped.
+	 * These options permit clients to control the use of memory-mapped
+	 * files on a per-file basis.
+	 *
+	 * The 'C' and 'c' flags are provided because the library support
+	 * for chopping up large strips into multiple smaller strips is not
+	 * application-transparent and as such can cause problems.  The 'c'
+	 * option permits applications that only want to look at the tags,
+	 * for example, to get the unadulterated TIFF tag information.

+/*
+ * TIFF Library.
+ * PixarLog Compression Support
+ *
+ * Contributed by Dan McCoy.
+ *
+ * PixarLog film support uses the TIFF library to store companded
+ * 11 bit values into a tiff file, which are compressed using the 
+ * zip compressor.  
+ *
+ * The codec can take as input and produce as output 32-bit IEEE float values 
+ * as well as 16-bit or 8-bit unsigned integer values.
+ *
+ * On writing any of the above are converted into the internal
+ * 11-bit log format.   In the case of  8 and 16 bit values, the
+ * input is assumed to be unsigned linear color values that represent
+ * the range 0-1.  In the case of IEEE values, the 0-1 range is assumed to
+ * be the normal linear color range, in addition over 1 values are
+ * accepted up to a value of about 25.0 to encode "hot" hightlights and such.
+ * The encoding is lossless for 8-bit values, slightly lossy for the
+ * other bit depths.  The actual color precision should be better
+ * than the human eye can perceive with extra room to allow for
+ * error introduced by further image computation.  As with any quantized
+ * color format, it is possible to perform image calculations which
+ * expose the quantization error. This format should certainly be less 
+ * susceptable to such errors than standard 8-bit encodings, but more
+ * susceptable than straight 16-bit or 32-bit encodings.
+ *
+ * On reading the internal format is converted to the desired output format.
+ * The program can request which format it desires by setting the internal
+ * pseudo tag TIFFTAG_PIXARLOGDATAFMT to one of these possible values:
+ *  PIXARLOGDATAFMT_FLOAT     = provide IEEE float values.
+ *  PIXARLOGDATAFMT_16BIT     = provide unsigned 16-bit integer values
+ *  PIXARLOGDATAFMT_8BIT      = provide unsigned 8-bit integer values
+ *
+ * alternately PIXARLOGDATAFMT_8BITABGR provides unsigned 8-bit integer
+ * values with the difference that if there are exactly three or four channels
+ * (rgb or rgba) it swaps the channel order (bgr or abgr).
+ *
+ * PIXARLOGDATAFMT_11BITLOG provides the internal encoding directly
+ * packed in 16-bit values.   However no tools are supplied for interpreting
+ * these values.
+ *
+ * "hot" (over 1.0) areas written in floating point get clamped to
+ * 1.0 in the integer data types.
+ *
+ * When the file is closed after writing, the bit depth and sample format
+ * are set always to appear as if 8-bit data has been written into it.
+ * That way a naive program unaware of the particulars of the encoding
+ * gets the format it is most likely able to handle.
+ *
+ * The codec does it's own horizontal differencing step on the coded
+ * values so the libraries predictor stuff should be turned off.
+ * The codec also handle byte swapping the encoded values as necessary
+ * since the library does not have the information necessary
+ * to know the bit depth of the raw unencoded buffer.
+ *
+ * NOTE: This decoder does not appear to update tif_rawcp, and tif_rawcc.
+ * This can cause problems with the implementation of CHUNKY_STRIP_READ_SUPPORT
+ * as noted in http://trac.osgeo.org/gdal/ticket/3894.   FrankW - Jan'11
