--- /dev/null
+Here is an alternate command-line user interface for the IJG JPEG software.
+It is designed for use under MS-DOS, and may also be useful on other non-Unix
+operating systems. (For that matter, this code works fine on Unix, but the
+standard command-line syntax is better on Unix because it is pipe-friendly.)
+
+With this user interface, cjpeg and djpeg accept multiple input file names
+on the command line; output file names are generated by substituting
+appropriate extensions. The user is prompted before any already-existing
+file will be overwritten. See usage.alt for details.
+
+Expansion of wild-card file specifications is useful but is not directly
+provided by this code. Most DOS C compilers have the ability to do wild-card
+expansion "behind the scenes", and we rely on that feature. On other systems,
+the shell may do it for you, as is done on Unix.
+
+Also, a DOS-specific routine is provided to determine available memory;
+this makes the -maxmemory switch unnecessary except in unusual cases.
+If you know how to determine available memory on a different system,
+you can easily add the necessary code. (And please send it along to
+jpeg-info@uunet.uu.net so we can include it in future releases!)
+
+
+INSTALLATION
+============
+
+You need to have the main IJG JPEG distribution, release 6 or later.
+Replace the standard cjpeg.c and djpeg.c files with the ones provided here.
+Then build the software as described in the main distribution's install.doc
+file, with these exceptions:
+
+* Define PROGRESS_REPORT in jconfig.h if you want the percent-done display.
+* Define NO_OVERWRITE_CHECK if you *don't* want overwrite confirmation.
+* You may ignore the USE_SETMODE and TWO_FILE_COMMANDLINE symbols discussed
+ in install.doc; these files do not use them.
+* As given, djpeg.c defaults to GIF output (not PPM output as in the standard
+ djpeg.c). If you want something different, modify DEFAULT_FMT.
+
+You may also need to do something special to enable filename wild-card
+expansion, assuming your compiler has that capability at all.
+
+Modify the standard usage.doc file as described in usage.alt. (If you want
+to use the Unix-style manual pages cjpeg.1 and djpeg.1, better fix them too.)
+
+
+Here are some specific notes for popular MS-DOS compilers:
+
+Borland C:
+ Add "-DMSDOS" to CFLAGS to enable use of the DOS memory determination code.
+ Link with the standard library file WILDARGS.OBJ to get wild-card expansion.
+
+Microsoft C:
+ Add "-DMSDOS" to CFLAGS to enable use of the DOS memory determination code.
+ Link with the standard library file SETARGV.OBJ to get wild-card expansion.
+ In the versions I've used, you must also add /NOE to the linker switches to
+ avoid a duplicate-symbol error from including SETARGV.
+
+DJGPP (we recommend version 2.0 or later):
+ Add "-DFREE_MEM_ESTIMATE=0" to CFLAGS. Wild-card expansion is automatic.

+(Most of the standard usage.doc file also applies to this alternate version,
+but replace its "GENERAL USAGE" section with the text below. Edit the text
+as necessary if you don't support wildcards or overwrite checking. Be sure
+to fix the djpeg switch descriptions if you are not defaulting to PPM output.
+Also, if you've provided an accurate memory-estimation procedure, you can
+probably eliminate the HINTS related to the -maxmemory switch.)
+
+
+GENERAL USAGE
+
+We provide two programs, cjpeg to compress an image file into JPEG format,
+and djpeg to decompress a JPEG file back into a conventional image format.
+
+The basic command line is:
+ cjpeg [switches] list of image files
+or
+ djpeg [switches] list of jpeg files
+
+Each file named is compressed or decompressed. The input file(s) are not
+modified; the output data is written to files which have the same names
+except for extension. cjpeg always uses ".jpg" for the output file name's
+extension; djpeg uses one of ".bmp", ".gif", ".ppm", ".rle", or ".tga",
+depending on what output format is selected by the switches.
+
+For example, to convert xxx.bmp to xxx.jpg and yyy.ppm to yyy.jpg, say:
+ cjpeg xxx.bmp yyy.ppm
+
+On most systems you can use standard wildcards to specify the list of input
+files; for example, on DOS "djpeg *.jpg" decompresses all the JPEG files in
+the current directory.
+
+If an intended output file already exists, you'll be asked whether or not to
+overwrite it. If you say no, the program skips that input file and goes on
+to the next one.
+
+You can intermix switches and file names; for example
+ djpeg -gif file1.jpg -targa file2.jpg
+decompresses file1.jpg into GIF format (file1.gif) and file2.jpg into Targa
+format (file2.tga). Only switches to the left of a given file name affect
+processing of that file; when there are conflicting switches, the rightmost
+one takes precedence.
+
+You can override the program's choice of output file name by using the
+-outfile switch, as in
+ cjpeg -outfile output.jpg input.ppm
+-outfile only affects the first input file name to its right.
+
+The currently supported image file formats are: PPM (PBMPLUS color format),
+PGM (PBMPLUS gray-scale format), BMP, GIF, Targa, and RLE (Utah Raster
+Toolkit format). (RLE is supported only if the URT library is available,
+which it isn't on most non-Unix systems.) cjpeg recognizes the input image
+format automatically, with the exception of some Targa-format files. You
+have to tell djpeg which format to generate.
+
+JPEG files are in the defacto standard JFIF file format. There are other,
+less widely used JPEG-based file formats, but we don't support them.
+
+All switch names may be abbreviated; for example, -grayscale may be written
+-gray or -gr. Most of the "basic" switches can be abbreviated to as little as
+one letter. Upper and lower case are equivalent (-BMP is the same as -bmp).
+British spellings are also accepted (e.g., -greyscale), though for brevity
+these are not mentioned below.

/*
- * Many machines require storage alignment: longs must start on 4-byte
- * boundaries, doubles on 8-byte boundaries, etc. On such machines, malloc()
- * always returns pointers that are multiples of the worst-case alignment
- * requirement, and we had better do so too.
- * There isn't any really portable way to determine the worst-case alignment
- * requirement. This module assumes that the alignment requirement is
- * multiples of sizeof(ALIGN_TYPE).
- * By default, we define ALIGN_TYPE as double. This is necessary on some
- * workstations (where doubles really do need 8-byte alignment) and will work
- * fine on nearly everything. If your machine has lesser alignment needs,
- * you can save a few bytes by making ALIGN_TYPE smaller.
- * The only place I know of where this will NOT work is certain Macintosh
- * 680x0 compilers that define double as a 10-byte IEEE extended float.
- * Doing 10-byte alignment is counterproductive because longwords won't be
- * aligned well. Put "#define ALIGN_TYPE long" in jconfig.h if you have
- * such a compiler.
+ * SIMD Ext: Most of SSE/SSE2 instructions require that the memory address
+ * is aligned to a 16-byte boundary; if not, a general-protection exception
+ * (#GP) is generated.

* header with a link to the next pool of the same class.
* Small and large pool headers are identical except that the latter's
* link pointer must be FAR on 80x86 machines.
- * Notice that the "real" header fields are union'ed with a dummy ALIGN_TYPE
- * field. This forces the compiler to make SIZEOF(small_pool_hdr) a multiple
- * of the alignment requirement of ALIGN_TYPE.

+%description
+The libjpeg package contains a library of functions for manipulating
+JPEG images, as well as simple client programs for accessing the
+libjpeg functions. Libjpeg client programs include cjpeg, djpeg,
+jpegtran, rdjpgcom and wrjpgcom. Cjpeg compresses an image file into
+JPEG format. Djpeg decompresses a JPEG file into a regular image
+file. Jpegtran can perform various useful transformations on JPEG
+files. Rdjpgcom displays any text comments included in a JPEG file.
+Wrjpgcom inserts text comments into a JPEG file.
+
+The libjpeg library in this package uses SIMD instructions if available.
+On a processor that supports SIMD instructions (MMX, SSE, etc),
+it runs 2-3 times faster than the original version of libjpeg.

+The libjpeg-devel package includes the header files and static libraries
+necessary for developing programs which will manipulate JPEG files using
+the libjpeg library.
+
+If you are going to develop programs which will manipulate JPEG images,
+you should install libjpeg-devel. You'll also need to have the libjpeg
+package installed.

# Makefile for Independent JPEG Group's software
+# Modified for x86 SIMD extension
# This makefile is for Microsoft Visual C++ on Windows NT (and 95?).
# It builds the IJG library as a statically linkable library (.LIB),
# and builds the sample applications as console-mode apps.
-# Thanks to Xingong Chang, Raymond Everly and others.
# Read installation instructions before saying "nmake" !!
-# To build an optimized library without debug info, say "nmake nodebug=1".
-# Pull in standard variable definitions
-!include <win32.mak>

+Independent JPEG Group's JPEG software release 6b
+ with x86 SIMD extension for IJG JPEG library version 1.02
+ == README ==
+-----------------------------------------------------------
+
+ ** Note **
+The accompanying documents related to x86 SIMD extension are written in
+Japanese. The English version of these documents is currently unavailable.
+I apologize for this inconvenience to international programmers.
+
+Most of the source code of the extension part is written in assembly
+language. To compile the source, you need NASM (netwide assembler).
+NASM is available from http://nasm.sourceforge.net/ or
+http://sourceforge.net/project/showfiles.php?group_id=6208 .
+
+At present, the x86 SIMD extension doesn't support 64-bit mode of
+AMD64 (x86_64).
+
+The x86 SIMD extension is an unofficial extension to the IJG JPEG
+software. Please do not send any questions about this distribution
+to the Independent JPEG Group.
+
+For conditions of distribution and use, see the IJG's README file.
+The same conditions apply to this SIMD-extended JPEG software.

+ *
+ * GIF ordinarily uses variable-width symbols, and the decoder will expect
+ * to ratchet up the symbol width after a fixed number of symbols.
+ * To simplify the logic and keep the expansion penalty down, we emit a
+ * GIF Clear code to reset the decoder just before the width would ratchet up.
+ * Thus, all the symbols in the output file will have the same bit width.
+ * Note that emitting the Clear codes at the right times is a mere matter of
+ * counting output symbols and is in no way dependent on the LZW patent.
+ *
+ * With a small basic pixel width (low color count), Clear codes will be
+ * needed very frequently, causing the file to expand even more. So this
+ * simplistic approach wouldn't work too well on bilevel images, for example.
+ * But for output of JPEG conversions the pixel width will usually be 8 bits
+ * (129 to 256 colors), so the overhead added by Clear symbols is only about
+ * one symbol in every 256.

- *
- * In this module we simply output each pixel value as a separate symbol;
- * thus, no compression occurs. In fact, there is expansion of one bit per
- * pixel, because we use a symbol width one bit wider than the pixel width.
- *
- * GIF ordinarily uses variable-width symbols, and the decoder will expect
- * to ratchet up the symbol width after a fixed number of symbols.
- * To simplify the logic and keep the expansion penalty down, we emit a
- * GIF Clear code to reset the decoder just before the width would ratchet up.
- * Thus, all the symbols in the output file will have the same bit width.
- * Note that emitting the Clear codes at the right times is a mere matter of
- * counting output symbols and is in no way dependent on the LZW patent.
- *
- * With a small basic pixel width (low color count), Clear codes will be
- * needed very frequently, causing the file to expand even more. So this
- * simplistic approach wouldn't work too well on bilevel images, for example.
- * But for output of JPEG conversions the pixel width will usually be 8 bits
- * (129 to 256 colors), so the overhead added by Clear symbols is only about
- * one symbol in every 256.
