++This is the latest version of the XV jumbo patches I originally created in
++February 2000 (but never distributed) and eventually updated and released in
++May 2004, prompted by a discussion on LWN (http://lwn.net/Articles/76391/).
++Information about the patches, updates to the patches, and the patches
++themselves can all be found here:
++
++ http://pobox.com/~newt/greg_xv.html
++ http://freshmeat.net/projects/xvjumbopatches/
++
++(Use the "Subscribe to new releases" link on the latter page if you want to
++be notified of new versions automatically; trivial registration required.)
++
++These patches incorporate all of the fix- and enhancement-patches available
++from John's XV site (http://www.trilon.com/xv/downloads.html and
++ftp://ftp.trilon.com/pub/xv/patches/), plus a number of my own fixes and
++additions (security-related and otherwise), plus quite a few from other
++people. They're still not fully complete, and it's probable they never
++will be, but I do plan to continue tinkering with them whenever the mood
++strikes--and I may even release them publicly on rare occasions. (At the
++current rate, once every few years may be the best we can hope for....)
++
++Also be aware that several other people have had the same idea over the
++years. Ones I've found, more or less by accident, include:
++

++ http://www.coara.or.jp/~sudakyo/XV_jp.html
++
++This is not an exhaustive list (e.g., Jörgen Grahn also had one). So far,
++most of the other patch-sets appear not to be as extensive or as up-to-date
++as my own, particularly now that the (very large) "Japanese extension" patches
++are incorporated--big thanks to Werner Fink of SuSE for that!
++
++Below I summarize the component patches that are encompassed by my jumbo
++bugfixes and jumbo enhancements patches, circa 2005. (As of 2007, they're
++distributed as a single monster-patch, and the "component patches" are now
++listed in the changelog section at the bottom of this file.) Unfortunately,
++some of my own additions never saw the light of day as standalone patches,
++but considering the number of overlaps (collisions) already implicit in the
++list, that would have been difficult to accomplish even if I'd had the time.
++
++Here's a quick guide to the "third-party" credits in the lists and changelog

++Finally, please note that these patches have not been blessed by John Bradley
++in any way (although I copied him on the May 2004 announcement and wrote to
++him again in May 2005), unless you count Debian's redistribution permission
++(Daniel Kirchheimer, 5 Dec 2005). Nor have I personally tested every change
++and feature! (See the BIG SCARY WARNING below for further caveats.) In other
++words, they're both completely unofficial and completely unguaranteed. But
++they seem to work for me. (And when they don't, I try to fix 'em--eventually,
++anyway... ;-) )

++How to build
++------------
++
++The following assumes you, the user, already have the libtiff,[1] libjpeg,[2]
++libpng,[3] zlib,[4] and JasPer[5] libraries downloaded, patched (if necessary),
++compiled, and installed, not to mention a C compiler and the bzip2,[6] tar,[7]
++patch,[8] and make[9] utilities. You should also have downloaded the original
++XV 3.10a source distribution from the XV Downloads page[10] and be able to edit
++its Makefile and config.h files as indicated in the INSTALL file. (Editing
++the Makefile will also allow you to disable some of the third-party libraries
++if you wish.) Finally, you should know what a Unix(-style) command line is,
++where to find one, and how to wield it with abandon (or at least with adult
++supervision)--and preferably not as the root user until the "make install"
++step. (A filesystem is a terrible thing to waste.)

++| BIG SCARY WARNING |
++| |
++| These patches work for Greg (and parts of them reportedly work for |
++| various other people), and so far Greg's CPU still computes and his |
++| hard disks haven't been wiped. But there's no guarantee that this |
++| will be the case for you! In particular, not every incorporated patch |
++| has been explicitly tested, nor has every possible subcase of the |
++| explicitly tested subset. (Read that again; it's grammatical.) Nor |
++| are these patches officially blessed by John Bradley in any way. In |
++| other words, if you use these patches, you do so at your own risk. |
++| (Greg doesn't believe there are any serious problems remaining, but |
++| then, what programmer ever does? Bugs happen.) |
++| |
+++-------------------------------------------------------------------------+
++
++Assuming you have the prerequisites out of the way and aren't scared
++off by the Big Scary Warning, here's the build procedure:
++
++ tar xvzf xv-3.10a-jumbo-patches-20070520.tar.gz
++ (or: gzip -dc xv-3.10a-jumbo-patches-20070520.tar.gz | tar xvf - )
++
++ tar xvzf xv-3.10a.tar.gz
++
++ cd xv-3.10a
++
++ patch -p1 < ../xv-3.10a-jumbo-fix-enh-patch-20070520.txt
++
++ edit Makefile and config.h as directed in INSTALL file (in particular,
++ ensure paths to external libraries and header files are correct)
++
++ make
++
++ ./xv your_favorite_image your_other_favorite_image etc.
++
++If everything seems to be working to your satisfaction, go ahead and install:
++
++ make -n install (and double-check that things will be installed
++ where you want them to be)
++
++ become root if necessary (e.g., type su)
++
++ make install
++ (or: sudo make install)
++
++That wasn't so hard, was it?

++ xvpic2.c, and xvhips.c, but keep in mind that these may not be exhaustive.)
++ Users who choose to overlook these security issues can enable any or all
++ of them by editing config.h.

++
++PCD patch for XV 3.10a Release Notes 2001/07/08.
++
++See also the progress notes at the end of this file. Thanks to all those
++contributors who have substantially improved this patch.
++
++These patches allow xv to read Kodak photocd files and choose which of the
++5 available resolutions one wants to view.
++
++When a photocd file is loaded, a dialog box asks which resolution you
++would like. The visual schnauzer builds thumbnails by reading the lowest
++resolution image. The selected resolution can be selected from the
++command line with the -pcd option:
++
++ [-pcd 0|1|2|3|4]
++
++where:
++
++ 0=192*128, base/16 resolution
++ 1=384*256, base/4 resolution
++ 2=768*512, base resolution
++ 3=1536*1024, 4base resolution
++ 4=3072*2048 16base resolution.
++
++Note that the Pro format is not supported.
++
++The command line option allows loops without the dialog box popping up, eg.:
++
++ xv -pcd 1 -wloop -wait 10 *.pcd
++
++The code is pretty crude and was written quickly for a specific purpose and
++has not really been cleaned up. It is poorly structured, full of debugging
++codes and verbose comments, and there is very little attempt at optimizing
++things. No profiling has been done.
++
++There is not yet support for overview files, nor is there a facility to
++use the higher resolution chroma planes from when viewing lower resolution
++images.
++
++It's only claim to fame is that it works and produces reasonable looking
++images.
++
++The outline of this is shamelessly derived from xvpbm.c to read the
++file, and xvtiffwr.c to handle the popup window and X stuff (X never
++has been my forte !), and the PhotoCD format information (though not
++the code) was found in Hadmut Danisch's (danisch@ira.uka.de) hpcdtoppm
++program in which he has reverse engineered the format by studying
++hex dumps of PhotoCDs ! The color stuff and Huffman decding were
++extensively revised by Matthew Francey.
++
++Feel free to send me comments or improvements, or even better, more
++information about the photo CD format ... hopefully someone who really
++knows what they are doing will tidy it up or do a neater job.

++
++---------
++
++The trace #define in xvpcd.c is now in the right place, and the ansi
++prototype for the magnify function has been fixed. Colin made me switch to
++xvbcopy() which seems like a good idea for System V victims.

++
++I have done some more work using your patch I thought you might be intested in.
++The major change was adding a size parameter to the LoadPCD; either -1 to mean
++the popup or else the size you desired. This allows batch mode processing,
++specifically xv -pcd <size> <filename>, and the visual schnauzer can work in
++quick mode (ie. you don't have to select each image size when it is building
++the icons)
++
++I have added an xbm file for the file type but haven't drawn an icon for it,
++this is in bitmaps/br_pcd.xbm. I will just send you the new files.

++
++This is David Clunie's patch for xv-3.00 tuned a bit to work
++on xv-3.10. The code's all the same except for replacing
++"trace" with "fprintf" in xvpcd.c and adding an "unsigned" qualifier to
++keep my compiler (gcc) happy. Oh yes, changed RFT_PCD to 20 as
++John Bradley has now used 15 through 19.

++
++Andrew's patch didn't include Colin's browser changes, so I redid the
++xv-3.10 update from scratch ... it seems pretty much the same as
++Andrew's changes. I also edited the Imakefile and Makefiles in order
++to support the PCD changes, as well as make the install process a
++little more flexible, with options to strip and set modes and so on.
++Also made RFT_PCD 25 so as not to conflict with magpic patch from Japan
++by Ikemoto Masahiro <ikeyan@airlab.cs.ritsumei.ac.jp>, and used his
++bitmap icon for pcd files.
++
++Now there are two versions of the patch, one which should be applied
++to the xv-3.10 distribution.
++
++The other should be applied to xv-3.10 AFTER Ikemoto Masahiro's
++Patch.magpic2.PhotoCD.XV319a, in order to add the browser features to
++the latter, as well as fixing a Makefile typo (was xcpcd.c not xvpcd.c)
++and including unistd.h for the SEEK_xxx constants in the magicpic
++stuff.

++Subject: Re: photo-cd patch for xv
++From: Matthew Francey <mdf@angoss.com>
++Date: Mon, 26 Mar 2001 15:37:55 +0000
++
++Attached is a revised version of xvpcd.c; the areas that I have
++re-written or changed are in a different coding style so you can tell
++what has changed. The GNU 'indent' program can be run against the file
++to enforce a consistent style ..
++
++Here is what I've done though:
++
++a) huffman table reader re-written, because it would fail on some
++ photocd files with "unusual" huffman codes.
++
++b) the huffman-coded corrections are now properly applied
++
++c) the corrections can sometimes over or underflow; clipping has been
++ introduced and effectively fixes the problem, but I suspect that
++ there is something deeper going on.
++
++d) the "official" YCC->sRGB transform is done. a "beyond 100% white"
++ mapping table was snarfed from ImageMagick. an option for using a
++ flat linear LUT was added -- this can make somewhat over-exposed images
++ look alot nicer.
++
++e) there were strange problems where the code wouldn't be able to find
++ the huffman tables and data for the 16base image (the bit-buffering
++ code was starting mid-sector, instead of at a sector boundary). Looking
++ at a pcd file with a hex editor suggests to me that it is possible to
++ just skip directly to these huffman tables -- no special "+12" and such
++ constants necessary. But I haven't tried this yet.
++
++The results: I've been able to read about 50 or 60 .pcd files [scattered
++in age from 6 years old to scans done last week] with this code without
++incident. Image quality at the high resolution is excellent. Even the
++trivial amount of LUT control is useful when dealing with over-exposed
++images.
++
++If I get around to it: finer LUT control to take advantage of the
++slightly extended dynamic range of PhotoCD scans, especially in regards to
++dark or somewhat underexposed scenes.

++Greg,
++ After winding up in dark lonely places trying to
++get xv-3.10a to build on FC5 I suspected I was missing
++something. Then I happened on your patch manifest
++in Slackware 10.2.
++
++I bandsawed the script a bit to use in propagating XV
++to a handful of personal FC5 machines. Attached for
++reference.
++
++Thanks for your effort!

++-- License and Disclaimer --
++
++This patch & script package was written by Alexey Spiridonov, and is
++licensed under the GNU GPLv2. There is NO WARRANTY.
++
++XV is copyrighted by John Bradley.
++
++-- What is this? --
++
++This is a small patch for XV that allows you to run scripts by pressing
++a key from F1 through F12 (or more, just change 12 to your number in the
++patch file).
++
++The patch enables a number of useful features. Here is a my set-up:
++
++F1: Losslessly rotate JPEG 90 degrees to the right.
++F2: Losslessly rotate JPEG 90 degrees to the left.
++
++F3: Print the current selection rectangle (on the terminal where xv was
++ launched). This is useful for quickly recording a bunch of positions in
++ an image. Use case:
++ I'm annotating face positions.
++ 1) Select Joe in picture, hit F3, type "Joe" in the terminal.
++ 2) Select Jane in the picture, ...
++ ...
++ n) Copy the text visible in the terminal, and paste it into the
++ JPEG comment.
++ Of course, i would write a more convenient script if I annotated faces
++ with any any frequency.
++
++F4: Edit JPEG comment (I use it for annotations/tags).
++
++F5: Log a 'losslessly rotate right' command for batch processing. This
++ writes the rotation command for the current file into a shell script
++ somewhere ("~/photos/bin/rotscript" by default). This is great for
++ slower computers because you don't have to wait for each image to
++ rotate; instead, you just rotate them all at once by running the
++ resulting script.
++F6: Log a 'losslessly rotate left' batch command.
++
++F8: Crop image on disk, but back-up the uncropped version. You can make
++ a succession of crops this way, with a backup made at every step.
++ This wastes disk space, so be sure to clean up once you get a crop you
++ like.
++F7: Undo the last crop done on this image. This can be repeated until you're
++ back at the original.
++
++-- Installation --
++
++I'll tell you how to get the set-up I described above. Of course, you can
++customize it to your heart's content.
++
++(( 1 ))
++
++Go to:
++
++ http://www.sonic.net/~roelofs/greg_xv.html
++
++and follow the XV install instructions there. If you are okay with
++reading shell scripts, you might also give this a shot:
++
++ http://sources.gentoo.org/viewcvs.py/*checkout*/gentoo-x86/media-gfx/xv/xv-3.10a-r12.ebuild
++
++When you're ready to type "make install", do the following to apply my patch:
++
++ $ cd WHEREVER_YOU_COMPILED_XV
++ $ patch -p1 --dry-run < PATH/TO/xv-3.10a-fkey-command-patch.greg-xv
++
++Hopefully, the above command won't complain; if it does, Greg Roelofs
++probably changed his patchset, and my patch has become out of date -- let me
++know. If that went well, run:
++
++ $ patch -p1 < PATH/TO/xv-3.10a-fkey-command-patch.greg-xv
++
++Now, simply recompile and install as described in the other instructions.
++
++(( 2 ))
++
++Copy 'jpegcrop.sh', 'jpegeditcom.sh', 'jpegundocrop.sh', 'jpegrot.sh',
++'jpeglogrot.sh' to some convenient directory.
++
++Suggestions: ~/photos/bin, /usr/local/bin, etc...
++
++Edit 'jpeglogrot.sh' and 'jpegeditcom.sh'. In the former, you need to
++customize the path to 'jpegrot.sh'. In the latter, you should make set
++your favorite editor. The spots to customize are marked as such.
++
++(( 3 ))
++
++Open .Xdefaults in your favorite text editor, and paste the following lines
++there:
++
++xv.F1command: ~/photos/bin/jpegrot.sh 90 %s
++xv.F2command: ~/photos/bin/jpegrot.sh 270 %s
++xv.F3command: @echo "The selection rect for '%s' is at (%d, %d) of size %dx%d."
++xv.F4command: @~/photos/bin/jpegeditcom.sh %s &
++xv.F5command: @~/photos/bin/jpeglogrot.sh 90 %s
++xv.F6command: @~/photos/bin/jpeglogrot.sh 270 %s
++xv.F7command: ~/photos/bin/jpegundocrop.sh %s
++xv.F8command: ~/photos/bin/jpegcrop.sh %s %d %d %d %d
++
++Change '~/photos/bin/' to the directory you chose in (( 2 )). In case you're
++wondering what the '@' symbol means, it tells XV not to reload the file
++after running this command. The default is to reload the file.
++
++-- Apologies --
++
++I didn't get a chance to run through the above instructions and check
++that they work. I know they're right in spirit, but I might've made a typo
++or two. Even if it's obvious to you, would you please let me know by writing
++to lesha at mit dot edu?

++ * xvjp2k.c - I/O subroutines for JPEG 2000 format pictures
++ *
++ * This module is a "shim" between XV and a JPEG 2000 CODEC in the open-source
++ * JasPer Library created by Michael D. Adams; for more information, see the URL
++ * "http://www.ece.uvic.ca/~mdadams/jasper". We don't use most of the other
++ * facilities in this library, so it's better to link XV with a UNIX "archive"
++ * representation of it, not a DLL.
++ *
++ * JPEG 2000 files can be represented in either of two general ways: The
++ * simplest representation is a "code stream", which often has a ".jpc" file
++ * name suffix and is organized much like a classical JPEG file, except that
++ * unfortunately, JPEG 2000 code streams indicate the no. of colors in an image
++ * but no longer give any clues about its color space (e.g., RGB or YCbCr).
++ * Instead, there is now a semantically higher-level representation, which often
++ * has a ".jp2" file name suffix and encapsulates a "code stream" with (possibly
++ * a lot of) color-space information, optionally including things like ICC
++ * correction tables.
++ *
++ * Compared to the IJG JPEG Library used in file "xvjpeg.c", one must solve
++ * several problems for color images when marrying JasPer to XV.
++ *
++ * 1. JPEG 2000 files can represent a wide range of image sizes, resolutions,
++ * and color spaces, not all of which can be easily rendered "as is" on a
++ * normal "X Windows" display, so we must carefully check a decoded image's
++ * parameters in order to reject anything that we can't handle gracefully.
++ *
++ * 2. JasPer prefers to decode/encode images using color-plane "slices", instead
++ * of interleaved pixels needed by "X Windows", so we must (de)interleave
++ * copies of the image buffer here.
++ *
++ * XXX Things to do:
++ *
++ * 1. In "LoadJP{2,C}()" try to handle the "quick" option, which requests
++ * faster loading of a reduced-size image for the visual schnauzer. The
++ * schnauzer's icon size is currently 80x60, so the old "xvjpeg.c" module tries
++ * to produce a 2X (160x120) image. Can we do the same?
++ *
++ * 2. In "StoreJP2K()", JasPer Library Version 1.701 apparently has no API to
++ * let the XV global "picComments" string be inserted in a JPEG 2000 comment
++ * record. If the library ever gets fixed, enhance our code accordingly.
++ *

++ making the parent shorter.
++
++ Note that there is currently no mechanism to program the no. of intermediate

++ * xvmgcsfx.c - Use the filters as input and output method.
++ *
++ * Features
++ * ========
++ * Use the filters as input and output method for load and save unsupported
++ * image format file. The filter command is recognized by definition of
++ * magic number or suffix in "~/.xv_mgcsfx" .
++ *
++ * Bugs
++ * ====
++ * There are many bugs.
++ * Let's go hunting for insects with an insect net. (it's all joke.)

++ * What is this?
++ *
++ * It is a package to show multi-lingual text.
++ *
++ * How to use?
++ *
++ * 1. Call ml_set_screen(Screen *scr);
++ * Tell this package the screen you use.
++ *
++ * 2. Call ml_set_charsets(struct char_spec spec[4], int gl, int gr);
++ * Tell this package the initial charsets.
++ * Gn is set to the charset specified by spec[n], respectively.
++ * GL and GR are set to G[gl] and G[gr], respectively.
++ * If first call, iso8859-1 font is loaded.
++ *
++ * 3. Call ml_draw_text(char *string);
++ * It Creates a bitmap, and returns it to you.
++ * If something goes wrong, it returns None.
++ * DON'T free the returned pixmaps!!
++ *
++ * BUGS:
++ * - Amharic and Tigrigna characters are strange.
++ * - Big5 is not supported.
++ * - Reverse direction is not supported.
++ * - Composing is not supported.
++ * - Cantonese can't be shown.
++ * - Texts which have many lines are buggy.
++ *
++ * NOTE:
++ * - Shifted JIS and Shifted GB must be converted to iso2022 in advance.
++ *
++ * Example of parameters to ml_set_charsets:
++ * - EUC-Japan
++ * spec = { {1, 94, 'B'}, G0 is US-ASCII
++ * {2, 94, 'B'}, G1 is JIS X0208
++ * {1, 94, 'J'}, G2 is (right-half of)JIS X0201
++ * {2, 94, 'D'} }; G3 is JIS X0212
++ * gl = 0; GL is G0
++ * gr = 1; GR is G1
++ *
++ * - Compound Text
++ * spec = { {1, 94, 'B'}, G0 is US-ASCII
++ * {1, 96, 'A'}, G1 is Latin-1
++ * {1, 94, 'B'}, G2 is US-ASCII (maybe unused)

++ * xvpic2.c supports the PIC2 format image file. It is used some
++ * Japanese personal computer users.
++ *
++ * The PIC2 format is designed by A.Yanagisawa. It is an excellent
++ * format except for its encode/decode speed. ;-)
++ *
++ * The features of the PIC2 format:
++ * - Powerful header information (included author, filename, title,
++ * saver, product number, created date and comment).
++ * - Reversible compression, and very high compression ratio (in many
++ * cases, a higher compression ratio than the JPEG compression;
++ * because of its compression method, PIC2 is especially good at
++ * pictures like cell animation).
++ * - Can handle full-color (24 bits) image.
++ * - Can include multi image blocks into one PIC2 file.
++ * - Have four different block format (P2SS, P2SF, P2BM and
++ * P2BI). P2SS format uses arithmetic compression for storing
++ * data. P2SF uses normal run-length compression. P2BM and P2BI is
++ * raw image format. Select any one according to the situation.
++ *
++ * Explanation of the PIC2 compression:
++
++ * - In the first place, try to record pixel color, uses color caches
++ * which keep some recent colors, and formed according to color's
++ * frequency. PIC2 has some color cache spaces that are switched by
++ * upper pixel value of current pixel. If cache is hit, record
++ * that.
++ * - Unfortunately, in the case of color cache didn't hit, record the
++ * difference from the value estimated with the value of upper and
++ * left pixel of current pixel (similar to PNG's AVG predictor).
++ * - And extract image's color chain if exist, and record that (it
++ * results in image's outline).
++ * - In all cases, arithmetic compression is used in the final stage
++ * before writing the file, which in theory produces the ideal
++ * compression ratio (P2SS).
++ *
++ * Features
++ * ========
++ * - Support 3,6,9,12,15,18,21,24bit PIC2 format (Load/Save).
++ * - Support all image block formats of PIC2 (Load/Save).
++ * - Support multi block PIC2 file (Load/Save).
++ *
++ *
++ * Bugs
++ * ====
++ * - Unsupport 8bit PIC2 image file.
++ *
++ * If you find other bugs (surely exist :-)), send me bug-report.
