number that the plugin may use to show plugin specific warning messages
or other information to the user. The plugin number
is generated by FreeImage and can differ everytime the plugin is
initialised.
If you want to create your own plugin you have to take some
rules into account. Plugin functions have to be compiled
__stdcall using the multithreaded c runtime libraries. Throwing
exceptions in plugin functions is allowed, as long as those exceptions
are being caught inside the same plugin. It is forbidden for a plugin
function to directly call FreeImage functions or to allocate memory
and pass it to the main DLL. Exception to this rule is the special file data
block that may be allocated the Open function. Allocating a FIBITMAP inside a
plugin can be using the function allocate_proc in the FreeImage structure,
which will allocate the memory using the DLL's c runtime library.

src/Source/LibJPEG/libjpeg.txt view on Meta::CPAN
Some applications need to use the JPEG library as an incremental memory-to-
memory filter: when the compressed data buffer is filled or emptied, they want
control to return to the outer loop, rather than expecting that the buffer can
be emptied or reloaded within the data source/destination manager subroutine.
The library supports this need by providing an "I/O suspension" mode, which we
describe in this section.
The I/O suspension mode is not a panacea: nothing is guaranteed about the
maximum amount of time spent in any one call to the library, so it will not
eliminate response-time problems in single-threaded applications. If you
need guaranteed response time, we suggest you "bite the bullet" and implement
a real multi-tasking capability.
To use I/O suspension, cooperation is needed between the calling application
and the data source or destination manager; you will always need a custom
source/destination manager. (Please read the previous section if you haven't
already.) The basic idea is that the empty_output_buffer() or
fill_input_buffer() routine is a no-op, merely returning FALSE to indicate
that it has done nothing. Upon seeing this, the JPEG library suspends
operation and returns to its caller. The surrounding application is
src/Source/LibJPEG/libjpeg.txt view on Meta::CPAN
being displayed. This has two benefits:
* You can limit buildup of unprocessed data in your input buffer.
* You can eliminate extra display passes by paying attention to the
state of the library's input processing.
The first of these benefits only requires interspersing calls to
jpeg_consume_input() with your display operations and any other processing
you may be doing. To avoid wasting cycles due to backtracking, it's best to
call jpeg_consume_input() only after a hundred or so new bytes have arrived.
This is discussed further under "I/O suspension", above. (Note: the JPEG
library currently is not thread-safe. You must not call jpeg_consume_input()
from one thread of control if a different library routine is working on the
same JPEG object in another thread.)
When input arrives fast enough that more than one new scan is available
before you start a new output pass, you may as well skip the output pass
corresponding to the completed scan. This occurs for free if you pass
cinfo.input_scan_number as the target scan number to jpeg_start_output().
The input_scan_number field is simply the index of the scan currently being
consumed by the input processor. You can ensure that this is up-to-date by
emptying the input buffer just before calling jpeg_start_output(): call
jpeg_consume_input() repeatedly until it returns JPEG_SUSPENDED or
JPEG_REACHED_EOI.

src/Source/LibPNG/INSTALL view on Meta::CPAN
After you have built libpng, the definitions that were recorded in
pnglibconf.h are available to your application (pnglibconf.h is included
in png.h and gets installed alongside png.h and pngconf.h in your
$PREFIX/include directory). Do not edit pnglibconf.h after you have built
libpng, because than the settings would not accurately reflect the settings
that were used to build libpng.
XV. Configuring libpng for multiprocessing
Libpng uses setjmp()/longjmp() for error handling. Unfortunately setjmp()
is known to be not thread-safe on some platforms and we don't know of
any platform where it is guaranteed to be thread-safe. Therefore, if
your application is going to be using multiple threads, you should
configure libpng with PNG_NO_SETJMP in your pngusr.dfa file, with
-DPNG_NO_SETJMP on your compile line, or with
#undef PNG_SETJMP_SUPPORTED
in your pnglibconf.h or pngusr.h.
XVI. Other sources of information about libpng:
Further information can be found in the README and libpng-manual.txt
src/Source/LibPNG/libpng-manual.txt view on Meta::CPAN
Libpng uses zlib for its compression and decompression of PNG files.
Further information about zlib, and the latest version of zlib, can
be found at the zlib home page, <http://www.info-zip.org/pub/infozip/zlib/>.
The zlib compression utility is a general purpose utility that is
useful for more than PNG files, and can be used without libpng.
See the documentation delivered with zlib for more details.
You can usually find the source files for the zlib utility wherever you
find the libpng source files.
Libpng is thread safe, provided the threads are using different
instances of the structures. Each thread should have its own
png_struct and png_info instances, and thus its own image.
Libpng does not protect itself against two threads using the
same instance of a structure.
II. Structures
There are two main structures that are important to libpng, png_struct
and png_info. Both are internal structures that are no longer exposed
in the libpng interface (as of libpng 1.5.0).
The png_info structure is designed to provide information about the
PNG file. At one time, the fields of png_info were intended to be
src/Source/LibPNG/libpng-manual.txt view on Meta::CPAN
were added to the library.
We implemented support for I/O states by adding png_ptr member io_state
and functions png_get_io_chunk_name() and png_get_io_state() in pngget.c
We added PNG_TRANSFORM_GRAY_TO_RGB to the available high-level
input transforms.
Checking for and reporting of errors in the IHDR chunk is more thorough.
Support for global arrays was removed, to improve thread safety.
Some obsolete/deprecated macros and functions have been removed.
Typecasted NULL definitions such as
#define png_voidp_NULL (png_voidp)NULL
were eliminated. If you used these in your application, just use
NULL instead.
The png_struct and info_struct members "trans" and "trans_values" were
changed to "trans_alpha" and "trans_color", respectively.
src/Source/LibPNG/libpng.3 view on Meta::CPAN

// For multi-threaded decoding we need to use 3 rows of 16 pixels as delay line.
//
// Reason is: the deblocking filter cannot deblock the bottom horizontal edges
// immediately, and needs to wait for first few rows of the next macroblock to
// be decoded. Hence, deblocking is lagging behind by 4 or 8 pixels (depending
// on strength).
// With two threads, the vertical positions of the rows being decoded are:
// Decode: [ 0..15][16..31][32..47][48..63][64..79][...
// Deblock: [ 0..11][12..27][28..43][44..59][...
// If we use two threads and two caches of 16 pixels, the sequence would be:
// Decode: [ 0..15][16..31][ 0..15!!][16..31][ 0..15][...
// Deblock: [ 0..11][12..27!!][-4..11][12..27][...
// The problem occurs during row [12..15!!] that both the decoding and
// deblocking threads are writing simultaneously.
// With 3 cache lines, one get a safe write pattern:
// Decode: [ 0..15][16..31][32..47][ 0..15][16..31][32..47][0..
// Deblock: [ 0..11][12..27][28..43][-4..11][12..27][28...
// Note that multi-threaded output _without_ deblocking can make use of two
// cache lines of 16 pixels only, since there's no lagging behind. The decoding
// and output process have non-concurrent writing:
// Decode: [ 0..15][16..31][ 0..15][16..31][...
// io->put: [ 0..15][16..31][ 0..15][...
