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.

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. ++ ++david (dclunie@dclunie.com) ++ ++--------- ++ ++The trace #define in xvpcd.c is now in the right place, and the ansi ++prototype for the magnify function has been fixed.

Oh yes, changed RFT_PCD to 20 as ++John Bradley has now used 15 through 19. ++ ++--------- ++ ++From: dclunie@flash.us.com (David A. Clunie) ++Date: Thu Jun 15 14:43:46 GMT+0300 1995 ++ ++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.

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 )).

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.

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. ++ * ++ * ++ * Author ++ * ====== ++ * IKEMOTO Masahiro <ikeyan@airlab.cs.ritsumei.ac.jp> ++ */ ++ ++#define PIC2_IGNORE_UNUSED_FUNCTIONS ++#define NEEDSDIR ++ ++#include "xv.h" ++#include <setjmp.h> ++ ++#ifdef HAVE_PIC2 ++ ++typedef unsigned long pixel; ++ ++#define pic2_cextoshort(addr) ( \ ++ (((short) (((byte *) addr)[0])) << 8) | \ ++ ( (short) (((byte *) addr)[1])) \ ++) ++#define pic2_cextolong(addr) ( \ ++ (((long) (((byte *) addr)[0])) << 24) | \ ++ (((long) (((byte *) addr)[1])) << 16) | \ ++ (((long) (((byte *) addr)[2])) << 8) | \ ++ ( (long) (((byte *) addr)[3])) \ ++) ++#define pic2_shorttocex(addr, n) { \ ++ ((byte *) addr)[0] = (((unsigned short) (n) >> 8) & 0xff); \ ++ ((byte *) addr)[1] = ( (unsigned short) (n) & 0xff); \ ++} ++#define pic2_longtocex(addr, n) { \ ++ ((byte *) addr)[0] = (((unsigned long) (n) >> 24) & 0xff); \ ++ ((byte *) addr)[1] = (((unsigned long) (n) >> 16) & 0xff); \ ++ ((byte *) addr)[2] = (((unsigned long) (n) >> 8) & 0xff); \ ++ ((byte *) addr)[3] = ( (unsigned long) (n) & 0xff); \ ++} ++#define pic2_shift_bits(b, n) (((n) > 0) ?
