* and it also interfered with desired capabilities such as quantizing to an
* externally-supplied colormap. We have therefore abandoned that approach.

it is your responsibility --- jpeg_destroy() won't. Ditto for the error
handler structure.
Typical code:
jpeg_destroy_compress(&cinfo);
8. Aborting.
If you decide to abort a compression cycle before finishing, you can clean up
in either of two ways:
* If you don't need the JPEG object any more, just call
jpeg_destroy_compress() or jpeg_destroy() to release memory. This is
legitimate at any point after calling jpeg_create_compress() --- in fact,
it's safe even if jpeg_create_compress() fails.
* If you want to re-use the JPEG object, call jpeg_abort_compress(), or call
jpeg_abort() which works on both compression and decompression objects.
This will return the object to an idle state, releasing any working memory.

how to generate a message, only where to send it.
format_message (j_common_ptr cinfo, char * buffer)
Constructs a readable error message string based on the error info
stored in cinfo->err. This method is called by output_message. Few
applications should need to override this method. One possible
reason for doing so is to implement dynamic switching of error message
language.
emit_message (j_common_ptr cinfo, int msg_level)
Decide whether or not to emit a warning or trace message; if so,
calls output_message. The main reason for overriding this method
would be to abort on warnings. msg_level is -1 for warnings,
0 and up for trace messages.
Only error_exit() and emit_message() are called from the rest of the JPEG
library; the other two are internal to the error handler.
The actual message texts are stored in an array of strings which is pointed to
by the field err->jpeg_message_table. The messages are numbered from 0 to
err->last_jpeg_message, and it is these code numbers that are used in the
src/Source/LibJPEG/libjpeg.txt view on Meta::CPAN
might never get to the bottom of the image before being aborted, resulting
in the lower part of the screen being several passes worse than the upper.
In most cases it's probably best to abort an output pass only if the whole
file has arrived and you want to begin the final output pass immediately.
When receiving data across a communication link, we recommend always using
the current input scan number for the output target scan number; if a
higher-quality final pass is to be done, it should be started (aborting any
incomplete output pass) as soon as the end of file is received. However,
many other strategies are possible. For example, the application can examine
the parameters of the current input scan and decide whether to display it or
not. If the scan contains only chroma data, one might choose not to use it
as the target scan, expecting that the scan will be small and will arrive
quickly. To skip to the next scan, call jpeg_consume_input() until it
returns JPEG_REACHED_SOS or JPEG_REACHED_EOI. Or just use the next higher
number as the target scan for jpeg_start_output(); but that method doesn't
let you inspect the next scan's parameters before deciding to display it.
In buffered-image mode, jpeg_start_decompress() never performs input and
thus never suspends. An application that uses input suspension with
buffered-image mode must be prepared for suspension returns from these
routines:
* jpeg_start_output() performs input only if you request 2-pass quantization
and the target scan isn't fully read yet. (This is discussed below.)
* jpeg_read_scanlines(), as always, returns the number of scanlines that it
was able to produce before suspending.
src/Source/LibJPEG/libjpeg.txt view on Meta::CPAN
all.
If you want to create a "pure" abbreviated image file containing no tables,
just call "jpeg_suppress_tables(&cinfo, TRUE)" after constructing all the
tables. If you want to emit some but not all tables, you'll need to set the
individual sent_table fields directly.
To create an abbreviated image, you must also call jpeg_start_compress()
with a second parameter of FALSE, not TRUE. Otherwise jpeg_start_compress()
will force all the sent_table fields to FALSE. (This is a safety feature to
prevent abbreviated images from being created accidentally.)
To create a tables-only file, perform the same parameter setup that you
normally would, but instead of calling jpeg_start_compress() and so on, call
jpeg_write_tables(&cinfo). This will write an abbreviated datastream
containing only SOI, DQT and/or DHT markers, and EOI. All the quantization
and Huffman tables that are currently defined in the compression object will
be emitted unless their sent_tables flag is already TRUE, and then all the
sent_tables flags will be set TRUE.
A sure-fire way to create matching tables-only and abbreviated image files
src/Source/LibJPEG/libjpeg.txt view on Meta::CPAN
resulting file will be invalid. For transcoding from an existing JPEG file,
we recommend using jpeg_copy_critical_parameters(). This routine initializes
all the compression parameters to default values (like jpeg_set_defaults()),
then copies the critical information from a source decompression object.
The decompression object should have just been used to read the entire
JPEG input file --- that is, it should be awaiting jpeg_finish_decompress().
jpeg_write_coefficients() marks all tables stored in the compression object
as needing to be written to the output file (thus, it acts like
jpeg_start_compress(cinfo, TRUE)). This is for safety's sake, to avoid
emitting abbreviated JPEG files by accident. If you really want to emit an
abbreviated JPEG file, call jpeg_suppress_tables(), or set the tables'
individual sent_table flags, between calling jpeg_write_coefficients() and
jpeg_finish_compress().
Progress monitoring
-------------------
Some applications may need to regain control from the JPEG library every so
often. The typical use of this feature is to produce a percent-done bar or

2. All "large" objects (including JSAMPARRAYs and JBLOCKARRAYs) must also be
allocated during initial setup.
3. realize_virt_arrays will be called at the completion of initial setup.
The above conventions ensure that sufficient information is available
for it to choose a good size for virtual array buffers.
Small objects of any lifespan may be allocated at any time. We expect that
the total space used for small objects will be small enough to be negligible
in the realize_virt_arrays computation.
In a virtual-memory machine, we simply pretend that the available space is
infinite, thus causing realize_virt_arrays to decide that it can allocate all
the virtual arrays as full-size in-memory buffers. The overhead of the
virtual-array access protocol is very small when no swapping occurs.
A virtual array can be specified to be "pre-zeroed"; when this flag is set,
never-yet-written sections of the array are set to zero before being made
available to the caller. If this flag is not set, never-written sections
of the array contain garbage. (This feature exists primarily because the
equivalent logic would otherwise be needed in jdcoefct.c for progressive
JPEG mode; we may as well make it available for possible other uses.)

src/Source/LibPNG/CHANGES view on Meta::CPAN
The shared-library makefiles were linking to libpng.so.0 instead of
libpng.so.3 compatibility as the library.
Version 1.2.11beta2 [June 2, 2006]
Increased sprintf buffer from 50 to 52 chars in pngrutil.c to avoid
buffer overflow.
Fixed bug in example.c (png_set_palette_rgb -> png_set_palette_to_rgb)
Version 1.2.11beta3 [June 5, 2006]
Prepended "#! /bin/sh" to ltmail.sh and contrib/pngminus/*.sh (Cosmin).
Removed the accidental leftover Makefile.in~ (Cosmin).
Avoided potential buffer overflow and optimized buffer in
png_write_sCAL(), png_write_sCAL_s() (Cosmin).
Removed the include directories and libraries from CFLAGS and LDFLAGS
in scripts/makefile.gcc (Nelson A. de Oliveira, Cosmin).
Version 1.2.11beta4 [June 6, 2006]
Allow zero-length IDAT chunks after the entire zlib datastream, but not
after another intervening chunk type.
Version 1.0.19rc1, 1.2.11rc1 [June 13, 2006]
src/Source/LibPNG/CHANGES view on Meta::CPAN
Version 1.4.0beta100 [November 14, 2009]
Removed ASM builds from projects/visualc6 and projects/visualc71
Removed scripts/makefile.nommx and makefile.vcawin32
Revised CMakeLists.txt to account for new location of libpng-config.in
and libpng-pc.in
Updated INSTALL to reflect removal and relocation of files.
Version 1.4.0beta101 [November 14, 2009]
Restored the binary files (*.jpg, *.png, some project files) that were
accidentally deleted from the zip and 7z distributions when the xcode
project was added.
Version 1.4.0beta102 [November 18, 2009]
Added libpng-config.in and libpng-pc.in to the zip and 7z distributions.
Fixed a typo in projects/visualc6/pngtest.dsp, introduced in beta100.
Moved descriptions of makefiles and other scripts out of INSTALL into
scripts/README.txt
Updated the copyright year in scripts/pngwin.rc from 2006 to 2009.
Version 1.4.0beta103 [November 21, 2009]
src/Source/LibPNG/CHANGES view on Meta::CPAN
calls to spurious functions if all transforms are disabled and slightly
simplifies those functions. Pngvalid modified to handle this.
A minor change is to stop the strip_16 and expand_16 interfaces from
disabling each other; this allows the future alpha premultiplication
code to use 16-bit intermediate values while still producing 8-bit output.
png_do_background and png_do_gamma have been simplified to take a single
pointer to the png_struct rather than pointers to every item required
from the png_struct. This makes no practical difference to the internal
code.
A serious bug in the pngvalid internal routine 'standard_display_init' has
been fixed - this failed to initialize the red channel and accidentally
initialized the alpha channel twice.
Changed png_struct jmp_buf member name from png_jmpbuf to tmp_jmpbuf to
avoid a possible clash with the png_jmpbuf macro on some platforms.
Version 1.5.3beta05 [May 6, 2011]
Added the "_POSIX_SOURCE" feature test macro to ensure libpng sees the
correct API. _POSIX_SOURCE is defined in pngpriv.h, pngtest.c and
pngvalid.c to ensure that POSIX conformant systems disable non-POSIX APIs.
Removed png_snprintf and added formatted warning messages. This change adds
internal APIs to allow png_warning messages to have parameters without
src/Source/LibPNG/CHANGES view on Meta::CPAN
Do not use __restrict when GNUC is <= 3.1
Removed references to png_zalloc() and png_zfree() from the manual.
Fixed configurations where floating point is completely disabled. Because
of the changes to support symbol prefixing PNG_INTERNAL_FUNCTION declares
floating point APIs during libpng builds even if they are completely
disabled. This requires the png floating point types (png_double*) to be
declared even though the functions are never actually defined. This
change provides a dummy definition so that the declarations work, yet any
implementation will fail to compile because of an incomplete type.
Re-eliminated the use of strcpy() in pngtest.c. An unncessary use of
strcpy() was accidentally re-introduced in libpng16; this change replaces
it with strncpy().
Eliminated use of png_sizeof(); use sizeof() instead.
Use a consistent style for (sizeof type) and (sizeof (array))
Cleanup of png_set_filler(). This function does very different things on
read and write. In libpng 1.6 the two cases can be distinguished and
considerable code cleanup, and extra error checking, is possible. This
makes calls on the write side that have no effect be ignored with a
png_app_error(), which can be disabled in the app using
png_set_benign_errors(), and removes the spurious use of usr_channels
on the read side.

part plus guessing a gAMA value requires code to pass selected RGB values
through the profile.
Version 1.6.0beta30 [October 24, 2012]
Changed ICC profile matrix/vector types to not depend on array type rules.
By the ANSI-C standard the new types should be identical to the previous
versions, and all known versions of gcc tested with the previous versions
except for GCC-4.2.1 work with this version. The change makes the ANSI-C
rule that const applied to an array of elements applies instead to the
elements in the array moot by explicitly applying const to the base
elements of the png_icc_matrix and png_icc_vector types. The accidental
(harmless) 'const' previously applied to the parameters of two of the
functions have also been removed.
Added a work around for GCC 4.2 optimization bug.
Marked the broken (bad white point) original HP sRGB profiles correctly and
correct comments.
Added -DZ_SOLO to contrib/pngminim/*/makefile to work with zlib-1.2.7
Use /MDd for vstudio debug builds. Also added pngunkown to the vstudio
builds, fixed build errors and corrected a minor exit code error in
pngvalid if the 'touch' file name is invalid.
Add updated WARNING file to projects/vstudio from libpng 1.5/vstudio
