+
+/*
+ * 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.

+ * Process library-specific flags in the open mode string.
+ * The following flags may be used to control intrinsic library
+ * behaviour that may or may not be desirable (usually for
+ * compatibility with some application that claims to support
+ * 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
