|
||||
Extend the entropy decoding structure, so that extraneous bytes between
|
||||
compressed scan data and following marker can be reported correctly.
|

Thank to Nigel Tao for hint.
|

|
||||
Add jpegtran -wipe option and extension for -crop.
|

|
||||
compresses the named image file, or the standard input if no file is
|
||||
named, and produces a JPEG/JFIF file on the standard output.
|
||||
The currently supported input file formats are: PPM (PBMPLUS color
|
||||
format), PGM (PBMPLUS gray-scale format), BMP, Targa, and RLE (Utah Raster
|
||||
format), PGM (PBMPLUS grayscale format), BMP, Targa, and RLE (Utah Raster

.TP
|
||||
.B \-bgycc
|
||||
Create big gamut YCC JPEG file.
|
||||
In this type of encoding the color difference components are quantized
|
||||
further by a factor of 2 compared to the normal Cb/Cr values, thus creating
|
||||
space to allow larger color values with higher saturation than the normal
|
||||
gamut limits to be encoded. In order to compensate for the loss of color
|
||||
fidelity compared to a normal YCC encoded file, the color quantization
|
||||
tables can be adjusted accordingly. For example,
|
||||
.B cjpeg \-bgycc \-quality
|
||||
80,90 will give similar results as
|
||||
.B cjpeg \-quality
|
||||
80.
|
||||
.B Caution:
|
||||
For correct decompression a decoder with big gamut YCC support (JFIF
|
||||
version 2) is required. An old decoder may or may not display a big
|
||||
gamut YCC encoded JPEG file, depending on JFIF version check and
|
||||
corresponding warning/error configuration. In case of a granted
|
||||
decompression the old decoder will display the image with half

saturated colors.

Currently, 9-bit to 12-bit support does not work on 16-bit-int machines.

|

Note that a 12-bit version will not read 8-bit JPEG files, nor vice versa;

so you'll want to keep around a regular 8-bit compilation as well.

(Run-time selection of data depth, to allow a single copy that does both,

The PPM writer (wrppm.c) will normally write 2-byte binary PPM or PGM

format, maxval=MAXJSAMPLE, when compiled with BITS_IN_JSAMPLE>8. Since this

of djpeg to keep around. But hopefully you won't need it for very long.

Of course, if you are working with 12-bit data, you probably have it stored

Note that a 12-bit version of cjpeg always runs in "-optimize" mode, in
|
||||
order to generate valid Huffman tables. This is necessary because our
|
||||
default Huffman tables only cover 8-bit data.
|

Note:
|
||||
The standard Huffman tables are only valid for 8-bit data precision. If
|
||||
you selected more than 8-bit data precision, cjpeg uses arithmetic coding
|
||||
by default. The Huffman encoder normally uses entropy optimization to
|
||||
compute usable tables for higher precision. Otherwise, you'll have to

supply different default Huffman tables.

5. Move the application .exe files from `app`\Release to an

|
||||
Note:
|
||||
There seems to be an optimization bug in the compiler which causes the
|
||||
self-test to fail with the color quantization option.
|
||||
We have disabled optimization for the file jquant2.c in the library
|
||||
project file which causes the self-test to pass properly.
|

|

Microsoft Windows, Visual Studio 2017 (v15):
|
||||
|
||||
We include makefiles that should work as project files in Visual Studio
|
||||
2017 (v15) or later. There is a library makefile that builds the IJG
|
||||
library as a static Win32 library, and application makefiles that build
|
||||
the sample applications as Win32 console applications. (Even if you only
|
||||
want the library, we recommend building the applications so that you can
|
||||
run the self-test.)
|
||||
|
||||
To use:
|
||||
1. Open the Developer Command Prompt, change to the main directory and
|
||||
execute the command line
|
||||
NMAKE /f makefile.vs setup-v15
|
||||
This will move jconfig.vc to jconfig.h and makefiles to project files.
|
||||
(Note that the renaming is critical!)
|
||||
2. Open the solution file jpeg.sln, build the library project.
|
||||
a) If you are using Visual Studio more recent than
|
||||
2017 (v15), you'll probably get a message saying
|
||||
that the project files are being updated.
|
||||
b) If necessary, open the project properties and
|
||||
adapt the Windows Target Platform Version in
|
||||
the Configuration Properties, General section;
|
||||
we support the latest version at the time of release.
|
||||
3. Open the solution file apps.sln, build the application projects.
|
||||
4. To perform the self-test, execute the command line
|
||||
NMAKE /f makefile.vs test-build
|
||||
5. Move the application .exe files from `app`\Release to an
|
||||

* These processes all use a common table prepared by the routine below.
|

*
|
||||
* For most steps we can mathematically guarantee that the initial value
|
||||
* of x is within MAXJSAMPLE+1 of the legal range, so a table running from
|
||||
* -(MAXJSAMPLE+1) to 2*MAXJSAMPLE+1 is sufficient. But for the initial
|
||||
* limiting step (just after the IDCT), a wildly out-of-range value is
|
||||
* possible if the input data is corrupt. To avoid any chance of indexing
|
||||
* of x is within 2*(MAXJSAMPLE+1) of the legal range, so a table running
|
||||
* from -2*(MAXJSAMPLE+1) to 3*MAXJSAMPLE+2 is sufficient. But for the
|
||||
* initial limiting step (just after the IDCT), a wildly out-of-range value
|
||||
* is possible if the input data is corrupt. To avoid any chance of indexing
|
||||
* off the end of memory and getting a bad-pointer trap, we perform the
|
||||
* post-IDCT limiting thus:
|
||||
* x = range_limit[x & MASK];
|
||||
* x = (sample_range_limit - SUBSET)[(x + CENTER) & MASK];
|
||||
* where MASK is 2 bits wider than legal sample data, ie 10 bits for 8-bit
|
||||
* samples. Under normal circumstances this is more than enough range and
|
||||
* a correct output will be generated; with bogus input data the mask will
|
||||
* cause wraparound, and we will safely generate a bogus-but-in-range output.
|
||||
* For the post-IDCT step, we want to convert the data from signed to unsigned
|
||||
* representation by adding CENTERJSAMPLE at the same time that we limit it.
|
||||
* So the post-IDCT limiting table ends up looking like this:
|
||||
* CENTERJSAMPLE,CENTERJSAMPLE+1,...,MAXJSAMPLE,
|
||||
* MAXJSAMPLE (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),
|
||||
* 0 (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),
|
||||
* 0,1,...,CENTERJSAMPLE-1
|
||||
* Negative inputs select values from the upper half of the table after
|
||||
* masking.
|
||||
*
|
||||
* We can save some space by overlapping the start of the post-IDCT table
|
||||
* with the simpler range limiting table. The post-IDCT table begins at
|
||||
* sample_range_limit + CENTERJSAMPLE.
|
||||
* This is accomplished with SUBSET = CENTER - CENTERJSAMPLE.
|
||||
*
|
||||
* Note that the table is allocated in near data space on PCs; it's small

||||
* enough and used often enough to justify this.

defining BITS_IN_JSAMPLE as 8, 9, 10, 11, or 12.
|
||||
Note that a value larger than 8 causes JSAMPLE to be larger than a char,
|
||||
so it affects the surrounding application's image data.
|
||||
The sample applications cjpeg and djpeg can support deeper than 8-bit data
|
||||
only for PPM and GIF file formats; you must disable the other file formats
|
||||
to compile a 9-bit to 12-bit cjpeg or djpeg. (install.txt has more
|
||||
information about that.)
|
||||
Run-time selection and conversion of data precision are currently not
|
||||
supported and may be added later.
|
||||
Exception: The transcoding part (jpegtran) supports all settings in a
|
||||
single instance, since it operates on the level of DCT coefficients and
|
||||
not sample values.
|
||||
(If you need to include an 8-bit library and a 9-bit to 12-bit library for
|
||||
compression or decompression in a single application, you could probably do
|
||||
it by defining NEED_SHORT_EXTERNAL_NAMES for just one of the copies. You'd
|
||||
have to access the 8-bit and the 9-bit to 12-bit copies from separate
|
||||
application source files. This is untested ... if you try it, we'd like to
|
||||
hear whether it works!)
|
||||
|
||||
Note that a 12-bit library always compresses in Huffman optimization mode,
|
||||
in order to generate valid Huffman tables. This is necessary because our
|
||||
default Huffman tables only cover 8-bit data. If you need to output 12-bit
|
||||
files in one pass, you'll have to supply suitable default Huffman tables.
|
||||
You may also want to supply your own DCT quantization tables; the existing
|
||||
quality-scaling code has been developed for 8-bit use, and probably doesn't
|
||||
generate especially good tables for 12-bit.
|
||||
Note that the standard Huffman tables are only valid for 8-bit data precision.
|
||||
If you selected more than 8-bit data precision, cjpeg uses arithmetic coding
|
||||
by default. The Huffman encoder normally uses entropy optimization to
|
||||
compute usable tables for higher precision. Otherwise, you'll have to
|
||||
supply different default Huffman tables. You may also want to supply your
|
||||
own DCT quantization tables; the existing quality-scaling code has been
|
||||
developed for 8-bit use, and probably doesn't generate especially good tables
|
||||
for 9-bit to 12-bit.
|
||||
|
||||
The maximum number of components (color channels) in the image is determined
|
||||
by MAX_COMPONENTS. The JPEG standard allows up to 255 components, but we

# Makefile for Independent JPEG Group's software

|

# This makefile is suitable for Borland C on MS-DOS.
|
||||
# It works with Borland C++ 32-bit for DOS, revision 5.0 or later.
|
||||
# Thanks to Tom Wright and Ge' Weijers (original DOS) and
|
||||
# Joe Slater for adding 32-bit additions (needed for Borland
|
||||
# revision 5.5).
|
||||
|

# Read installation instructions before saying "make" !!

# The name of your C compiler:
|
||||
CC= bcc32
|
||||
|
||||
# You may need to adjust these cc options:
|
||||
CFLAGS= -O2 -w-par -w-stu -w-ccc -w-rch -w-aus
|
||||
# -w-par suppresses warnings about unused function parameters
|
||||
# -w-stu suppresses warnings about incomplete structures
|
||||
# -w-ccc suppresses warnings about compile-time-constant conditions
|
||||
# -w-rch suppresses warnings about unreachable code
|
||||
# Generally, we recommend defining any configuration symbols in jconfig.h,
|
||||
# NOT via -D switches here.
|
||||
|
||||
# Link-time cc options:
|
||||
LDFLAGS=
|

# -lc case-significant link

# Put here the object file name for the correct system-dependent memory

# Makefile for Independent JPEG Group's software

# 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>
|
||||
|
||||
# You may want to adjust these compiler options:
|
||||
CFLAGS= $(cflags) $(cdebug) $(cvars) -I.
|
||||
# Generally, we recommend defining any configuration symbols in jconfig.h,
|
||||
# NOT via -D switches here.
|
||||
|
||||
# Link-time options:
|
||||
LDFLAGS= $(ldebug) $(conlflags)
|
||||
|
||||
# To link any special libraries, add the necessary commands here.
|
||||
LDLIBS= $(conlibs)
|
||||
|
||||
# Put here the object file name for the correct system-dependent memory
|

|
||||
# provide adequate virtual memory.
