-Configuration Comments:
-----------------------
-Aside from the compression algorithm support, there are
-configuration-related defines that you can override in the Makefile
-or in the default configuration file tiffconf.h:
+NOTE:
+this is libtiff 3.5.6 beta, obtained from http://www.libtiff.org
+--------------
 
-COLORIMETRY_SUPPORT
-		if this is defined, support for the colorimetry
-		tags will be compiled in.
-JPEG_SUPPORT	if this is defined, support for the JPEG-related
-		tags will be compiled in.  Note that at the present
-		time the JPEG compression support is not included.
-YCBCR_SUPPORT	if this is defined, support for the YCbCr-related
-		tags will be compiled in.  Note that you'll want
-		YCBCR support for JPEG compression+decompression.
-CMYK_SUPPORT	if this is defined, support for the CMYK-related
-		tags will be compiled in.
-MMAP_SUPPORT	if this is set, and OS support exists for memory
-		mapping files, then the library will try to map
-		a file if it is opened for reading.  If mmap does
-		not exist on your system, or the mmap call fails
-		on the file, then the normal read system calls are
-		used.  It is not clear how useful this facility is.
 
-By default tiffconf.h defines COLORIMETRY_SUPPORT, JPEG_SUPPORT,
-YCBCR_SUPPORT, CMYK_SUPPORT.  MMAP_SUPPORT is not defined.
+TIFF Software Distribution
+--------------------------
+This file is just a placeholder; all the documentation is now in
+HTML in the html directory.  To view the documentation point your
+favorite WWW viewer at html/index.html; e.g.
 
-General Portability Comments:
-----------------------------
-I run this code on SGI machines (big-endian, MIPS CPU, 32-bit ints,
-IEEE floating point).  Makefiles exist for other platforms that the
-code runs on -- this work has mostly been done by other people.
-The code runs on Macintosh and PC-based systems, although I don't
-know all the particulars.
+    netscape html/index.html
 
-In general, I promise only that the code runs on SGI machines.
-I will, however, gladly take back fixes to make it work on other
-systems -- when the changes are reasonable unobtrusive.
+If you don't have an HTML viewer then you can read the HTML source
+or fetch a PostScript version of this documentation from the directory
 
-The software is written to assume an ANSI C compilation environment.
-If your compiler does not support ANSI function prototypes, const,
-and <stdarg.h> then you will have to make modifications to the
-software.  In the past I have tried to support compilers w/o const
-and systems w/o <stdarg.h>, but I am NO LONGER INTERESTED in these
-antiquated environments.  With the general availability of gcc, I
-see no reason to incorporate modifications to the software for these
-purposes.
+    ftp://ftp.sgi.com/graphics/tiff/doc
 
-I've tried to isolate as many of the OS-dependencies as possible in
-two files: tiffcomp.h and tif_<os>.c.  The latter file contains
-OS-specific routines to do I/O and I/O-related operations.  The
-UNIX (tif_unix.c), Macintosh (tif_apple.c), and VMS (tif_vms.c)
-code has had the most use; the MS/DOS support (tif_msdos.c) assumes
-some level of UNIX system call emulation (i.e. open, read, write,
-fstat, malloc, free).
+If you can't hack either of these options then basically what you
+want to do is:
 
-Machine dependencies such as byte order are determined on the
-fly and do not need to be specified.
+    % ./configure
+    % make
+    % su
+    # make install
 
-Two general portability-related defines are:
+More information, email contacts, and mailing list information can be 
+found online at http://www.libtiff.org/.
 
-BSDTYPES	Define this if your system does NOT define the
-		usual BSD typedefs: u_char, u_short, u_int, u_longs.
-HAVE_IEEEFP	Define this as 0 or 1 according to the floating point
-		format suported by the machine.  If your machine does
-		not support IEEE floating point then you will need to
-		add support to tif_machdep.c to convert between the
-		native format and IEEE format.
 
-Note that tiffcomp.h defines HAVE_IEEEFP to be 1 (BSDTYPES is not defined).
+Use and Copyright
+-----------------
+Silicon Graphics has seen fit to allow us to give this work away.  It
+is free.  There is no support or guarantee of any sort as to its
+operations, correctness, or whatever.  If you do anything useful with
+all or parts of it you need to honor the copyright notices.   I would
+also be interested in knowing about it and, hopefully, be acknowledged.
 
-Types and Portability:
----------------------
-The software makes extensive use of typedefs to promote portability.
-Two sets of typedefs are used, one for communication with clients
-of the library and one for internal data structures and parsing of the
-TIFF format.  There are interactions between these two to be careful
-of, but for the most part you should be able to deal with portability
-purely by fiddling with the following machine-dependent typedefs:
+The legal way of saying that is:
 
-uint16		16-bit unsigned integer		tiff.h
-int16		16-bit signed integer		tiff.h
-uint32		32-bit unsigned integer		tiff.h
-int32		32-bit signed integer		tiff.h
-dblparam_t	promoted type for floats	tiffcomp.h
+Copyright (c) 1988-1997 Sam Leffler
+Copyright (c) 1991-1997 Silicon Graphics, Inc.
 
-(to clarify dblparam_t, it is the type that float parameters are
-promoted to when passed by value in a function call.)
+Permission to use, copy, modify, distribute, and sell this software and 
+its documentation for any purpose is hereby granted without fee, provided
+that (i) the above copyright notices and this permission notice appear in
+all copies of the software and related documentation, and (ii) the names of
+Sam Leffler and Silicon Graphics may not be used in any advertising or
+publicity relating to the software without the specific, prior written
+permission of Sam Leffler and Silicon Graphics.
 
-The following typedefs are used throughout the library and interfaces
-to refer to certain objects whose size is dependent on the TIFF image
-structure:
+THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, 
+EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY 
+WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.  
 
-typedef	unsigned int ttag_t;	directory tag
-typedef	uint16 tdir_t;		directory index
-typedef	uint16 tsample_t;	sample number
-typedef	uint32 tstrip_t;	strip number
-typedef uint32 ttile_t;		tile number
-typedef	int32 tsize_t;		i/o size in bytes
-typedef	void* tdata_t;		image data ref
-typedef	void* thandle_t;	client data handle
-typedef	int32 toff_t;		file offset (should be off_t)
-typedef	unsigned char* tidata_t;internal image data
-
-Note that tstrip_t, ttile_t, and tsize_t are constrained to be
-no more than 32-bit quantities by 32-bit fields they are stored
-in in the TIFF image.  Likewise tsample_t is limited by the 16-bit
-field used to store the SamplesPerPixel tag.  tdir_t constrains
-the maximum number of IFDs that may appear in an image and may
-be an arbitrary size (w/o penalty).  ttag_t must be either int,
-unsigned int, pointer, or double because the library uses a varargs
-interface and ANSI restricts the type of the parameter before an
-ellipsis to be a promoted type.  toff_t is defined as int32 because
-TIFF file offsets are (unsigned) 32-bit quantities.  A signed
-value is used because some interfaces return -1 on error (sigh).
-Finally, note that tidata_t is used internally to the library to
-manipulate internal data.  User-specified data references are
-passed as opaque handles and only cast at the lowest layers where
-their type is presumed.
-
-General Comments:
-----------------
-The library is designed to hide as much of the details of TIFF as
-possible.  In particular, TIFF directories are read in their entirety
-into an internal format.  Only the tags known by the library are
-available to a user and certain tag data may be maintained that a user
-doesn't care about (e.g. transfer function tables).
-
-To add support for a new directory tag the following mods are needed:
-
-1. Define the tag in tiff.h.
-2. Add a field to the directory structure in tiffiop.h and define a
-   FIELD_* bit.
-3. Add an entry in the FieldInfo array defined at the top of tiff_dirinfo.c.
-4. Add entries in TIFFSetField1() and TIFFGetField1() for the new tag.
-5. (optional) If the value associated with the tag is not a scalar value
-   (e.g. the array for TransferFunction), then add the appropriate
-   code to TIFFReadDirectory() and TIFFWriteDirectory().  You're best
-   off finding a similar tag and cribbing code.
-6. Add support to TIFFPrintDirectory() in tiff_print.c to print the
-   tag's value.
-
-If you want to maintain portability, beware of making assumptions
-about data types.  Use the typedefs (uint16, etc. when dealing with
-data on disk and t*_t when stuff is in memory) and be careful about
-passing items through printf or similar vararg interfaces.
-
-To add support for a compression algorithm:
-
-1. Define the tag value in tiff.h.
-2. Edit the file tiff_compress.c to add an entry to the
-   CompressionSchemes[] array.
-3. Create a file with the compression scheme code, by convention files
-   are named tif_*.c (except perhaps on some systems where the tif_ prefix
-   pushes some filenames over 14 chars.
-4. Edit the Makefiles to include the new source file.
-
-A compression scheme, say foo, can have up to 10 entry points:
-
-TIFFfoo(tif)		/* initialize scheme and setup entry points in tif */
-fooPreDecode(tif)	/* called once per strip, after data is read,
-			   but before the first row in a strip is decoded */
-fooDecode*(tif, bp, cc, sample)/* decode cc bytes of data into the buffer */
-    fooDecodeRow(...)	/* called to decode a single scanline */
-    fooDecodeStrip(...)	/* called to decode an entire strip */
-    fooDecodeTile(...)	/* called to decode an entire tile */
-fooPreEncode(tif)	/* called once per strip/tile, before the first row in
-			   a strip is encoded */
-fooEncode*(tif, bp, cc, sample)/* encode cc bytes of user data (bp) */
-    fooEncodeRow(...)	/* called to decode a single scanline */
-    fooEncodeStrip(...)	/* called to decode an entire strip */
-    fooEncodeTile(...)	/* called to decode an entire tile */
-fooPostEncode(tif)	/* called once per strip/tile, just before data is written */
-fooSeek(tif, row)	/* seek forwards row scanlines from the beginning
-			   of a strip (row will always be >0 and <rows/strip */
-fooCleanup(tif)		/* called when compression scheme is replaced by user */
-
-Note that the encoding and decoding variants are only needed when
-a compression algorithm is dependent on the structure of the data.
-For example, Group 3 2D encoding and decoding maintains a reference
-scanline.  The sample parameter identifies which sample is to be
-encoded or decoded if the image is organized with PlanarConfig=2
-(separate planes).  This is important for algorithms such as JPEG.
-If PlanarConfig=1 (interleaved), then sample will always be 0.
-
-The library handles most I/O buffering.  There are two data buffers
-when decoding data: a raw data buffer that holds all the data in a
-strip, and a user-supplied scanline buffer that compression schemes
-place decoded data into.  When encoding data the data in the
-user-supplied scanline buffer is encoded into the raw data buffer (from
-where it's written).  Decoding routines should never have to explicitly
-read data -- a full strip/tile's worth of raw data is read and scanlines
-never cross strip boundaries.  Encoding routines must be cognizant of
-the raw data buffer size and call TIFFFlushData1() when necessary.
-Note that any pending data is automatically flushed when a new strip/tile is
-started, so there's no need do that in the tif_postencode routine (if
-one exists).  Bit order is automatically handled by the library when
-a raw strip or tile is filled.  If the decoded samples are interpreted
-by the decoding routine before they are passed back to the user, then
-the decoding logic must handle byte-swapping by overriding the tif_postdecode
-routine (set it to TIFFNoPostDecode) and doing the required work
-internally.  For an example of doing this look at the horizontal
-differencing code in the LZW decoding routines.
-
-The variables tif_rawcc, tif_rawdata, and tif_rawcp in a TIFF structure
-are associated with the raw data buffer.  tif_rawcc must be non-zero
-for the library to automatically flush data.  The variable
-tif_scanlinesize is the size a user's scanline buffer should be.  The
-variable tif_tilesize is the size of a tile for tiled images.  This
-should not normally be used by compression routines, except where it
-relates to the compression algorithm.  That is, the cc parameter to the
-tif_decode* and tif_encode* routines should be used in terminating
-decompression/compression.  This ensures these routines can be used,
-for example, to decode/encode entire strips of data.
-
-In general, if you have a new compression algorithm to add, work from
-the code for an existing routine.  In particular, tiff_dumpmode.c has
-the trivial code for the "nil" compression scheme, tiff_packbits.c is a
-simple byte-oriented scheme that has to watch out for buffer
-boundaries, and tiff_lzw.c has the LZW scheme that has the most
-complexity -- it tracks the buffer boundary at a bit level.
-
-Of course, using a private compression scheme (or private tags) limits
-the portability of your TIFF files.

+Low-level file handling
+~~~~~~~~~~~~~~~~~~~~~~~
+The functions in osfcn.h are unavailable when compiling under C, as it's a
+C++ header. Therefore they have been implemented here.
+
+Now, why have I done it this way?
+
+The definitive API library for RISC OS is Jonathan Coxhead's OSLib, which
+uses heavily optimised ARM assembler or even plain inline SWI calls for
+maximum performance and minimum runtime size. However, I don't want to make
+LIBTIFF need that to survive. Therefore I have also emulated the functions
+using macros to _swi() and _swix() defined in the swis.h header, and
+borrowing types from kernel.h, which is less efficient but doesn't need any
+third-party libraries.

+
+/*
+ * 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.
+ *
+ * The 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.

+	 * 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
+	 *
+	 * 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 probabyl 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.
