Slackware 13.0slackware-13.0
Wed Aug 26 10:00:38 CDT 2009 Slackware 13.0 x86_64 is released as stable! Thanks to everyone who helped make this release possible -- see the RELEASE_NOTES for the credits. The ISOs are off to the replicator. This time it will be a 6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD. We're taking pre-orders now at store.slackware.com. Please consider picking up a copy to help support the project. Once again, thanks to the entire Slackware community for all the help testing and fixing things and offering suggestions during this development cycle. As always, have fun and enjoy! -P.

+-I very much doubt that this is an exhaustive list. So far, most of the other
+-patch-sets appear not to be quite as extensive or as up-to-date as my own,
+-although the last three or four do include the [large] Japanese extension
+-patches that I omitted--not because they're unworthy, but simply because I
+-didn't find them until collisions between the two sets of patches had become
+-a large problem. (Maybe for the next release... I'd intended to try for
+-this release, but the security issues ended up taking almost all of my
+-available time. And, to be honest, from my perspective, inclusion of the
+-jp-extension patches is more for completeness' sake than personal interest,
+-so their priority is fairly low.)

++particularly now that the (very large) "Japanese extension" patches are

+
+ Below I summarize the component patches that are encompassed by my jumbo
+ bugfixes and jumbo enhancements patches. 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 this list, it would
+-have been difficult to accomplish even if I'd had the time. In any case,
+-they're present in these jumbo patches but not chongo's, so those who _really_
+-care can "subtract" the two sets of patches to see what I did.

+-there _is_ a "henceforth"--I expect to merge the patches into a single
+-jumbo patch. (Alternatively, I may simply freeze the current fix-patch
+-and continue to evolve only the enhancements patch; in particular, new
+-fixes would appear only in it. Either approach would be simple enough;
+-feedback as to which would be preferable is welcomed.)

++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.

++ * 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 - load and save routines for `PIC2' format pictures.
++ *
++ *
++ * Outline
++ * =======
++ * 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.
