with two spaces per indentation level. (This indentation convention is
handled automatically by GNU Emacs and many other text editors.)
Multi-word names should be written in lower case with underscores, e.g.,
multi_word_name (not multiWordName). Preprocessor symbols and enum constants
are similar but upper case (MULTI_WORD_NAME). Names should be unique within
the first fifteen characters. (On some older systems, global names must be
unique within six characters. We accommodate this without cluttering the
source code by using macros to substitute shorter names.)
We use function prototypes everywhere; we rely on automatic source code
transformation to feed prototype-less C compilers. Transformation is done
by the simple and portable tool 'ansi2knr.c' (courtesy of Ghostscript).
ansi2knr is not very bright, so it imposes a format requirement on function
declarations: the function name MUST BEGIN IN COLUMN 1. Thus all functions
should be written in the following style:
src/Source/LibJPEG/coderules.txt view on Meta::CPAN
so that the result is guaranteed to be of type size_t.
The JPEG library is intended to be used within larger programs. Furthermore,
we want it to be reentrant so that it can be used by applications that process
multiple images concurrently. The following rules support these requirements:
1. Avoid direct use of file I/O, "malloc", error report printouts, etc;
pass these through the common routines provided.
2. Minimize global namespace pollution. Functions should be declared static
wherever possible. (Note that our method-based calling conventions help this
a lot: in many modules only the initialization function will ever need to be
called directly, so only that function need be externally visible.) All
global function names should begin with "jpeg_", and should have an
abbreviated name (unique in the first six characters) substituted by macro
when NEED_SHORT_EXTERNAL_NAMES is set.
3. Don't use global variables; anything that must be used in another module
should be in the common data structures.
4. Don't use static variables except for read-only constant tables. Variables
that should be private to a module can be placed into private structures (see
the system architecture document, structure.txt).
5. Source file names should begin with "j" for files that are part of the
library proper; source files that are not part of the library, such as cjpeg.c
and djpeg.c, do not begin with "j". Keep source file names to eight
characters (plus ".c" or ".h", etc) to make life easy for MS-DOSers. Keep

routine.
The JPEG library does not rely heavily on the C library. In particular, C
stdio is used only by the data source/destination modules and the error
handler, all of which are application-replaceable. (cjpeg/djpeg are more
heavily dependent on stdio.) malloc and free are called only from the memory
manager "back end" module, so you can use a different memory allocator by
replacing that one file.
The code generally assumes that C names must be unique in the first 15
characters. However, global function names can be made unique in the
first 6 characters by defining NEED_SHORT_EXTERNAL_NAMES.
More info about porting the code may be gleaned by reading jconfig.txt,
jmorecfg.h, and jinclude.h.

* This file implements djpeg's "-map file" switch. It reads a source image
* and constructs a colormap to be supplied to the JPEG decompressor.
*
* Currently, these file formats are supported for the map file:
* GIF: the contents of the GIF's global colormap are used.
* PPM (either text or raw flavor): the entire file is read and
* each unique pixel value is entered in the map.
* Note that reading a large PPM file will be horrendously slow.
* Typically, a PPM-format map file should contain just one pixel
* of each desired color. Such a file can be extracted from an
* ordinary image PPM file with ppmtomap(1).
*
* Rescaling a PPM that has a maxval unequal to MAXJSAMPLE is not
* currently implemented.

*** Implications of DNL marker ***
Some JPEG files may use a DNL marker to postpone definition of the image
height (this would be useful for a fax-like scanner's output, for instance).
In these files the SOF marker claims the image height is 0, and you only
find out the true image height at the end of the first scan.
We could read these files as follows:
1. Upon seeing zero image height, replace it by 65535 (the maximum allowed).
2. When the DNL is found, update the image height in the global image
descriptor.
This implies that control modules must avoid making copies of the image
height, and must re-test for termination after each MCU row. This would
be easy enough to do.
In cases where image-size data structures are allocated, this approach will
result in very inefficient use of virtual memory or much-larger-than-necessary
temporary files. This seems acceptable for something that probably won't be a
mainstream usage. People might have to forgo use of memory-hogging options
(such as two-pass color quantization or noninterleaved JPEG files) if they

Updated scripts/makevms.com and added makevms.com to contrib/gregbook
and contrib/pngminus (Martin Zinser)
Version 1.0.5c [November 26, 1999]
Moved png_get_header_version from png.h to png.c, to accommodate ansi2knr.
Removed all global arrays (according to PNG_NO_GLOBAL_ARRAYS macro), to
accommodate making DLL's: Moved usr_png_ver from global variable to function
png_get_header_ver() in png.c. Moved png_sig to png_sig_bytes in png.c and
eliminated use of png_sig in pngwutil.c. Moved the various png_CHNK arrays
into pngtypes.h. Eliminated use of global png_pass arrays. Declared the
png_CHNK and png_pass arrays to be "const". Made the global arrays
available to applications (although none are used in libpng itself) when
PNG_NO_GLOBAL_ARRAYS is not defined or when PNG_GLOBAL_ARRAYS is defined.
Removed some extraneous "-I" from contrib/pngminus/makefile.std
Changed the PNG_sRGB_INTENT macros in png.h to be consistent with PNG-1.2.
Change PNG_SRGB_INTENT to PNG_sRGB_INTENT in libpng.txt and libpng.3
Version 1.0.5d [November 29, 1999]
Add type cast (png_const_charp) two places in png.c
Eliminated pngtypes.h; use macros instead to declare PNG_CHNK arrays.
Renamed "PNG_GLOBAL_ARRAYS" to "PNG_USE_GLOBAL_ARRAYS" and made available
src/Source/LibPNG/CHANGES view on Meta::CPAN

Updated png.rc in dll/msvc project
Revised makefile.dec to define and use LIBPATH and INCPATH
Increased size of global png_libpng_ver[] array from 12 to 18 chars.
Made global png_libpng_ver[], png_sig[] and png_pass_*[] arrays const.
Removed duplicate png_crc_finish() from png_handle_bKGD() function.
Added a warning when application calls png_read_update_info() multiple times.
Revised makefile.cygwin
Fixed bugs in iCCP support in pngrutil.c and pngwutil.c.
Replaced png_set_empty_plte_permitted() with png_permit_mng_features().
Version 1.0.9beta2 [November 19, 2000]
Renamed the "dll" subdirectory "projects".
Added borland project files to "projects" subdirectory.
Set VS_FF_PRERELEASE and VS_FF_PATCHED flags in msvc/png.rc when appropriate.
src/Source/LibPNG/CHANGES view on Meta::CPAN
Eliminated deprecated png_read_init_3() and png_write_init_3() functions.
Version 1.4.0beta55 [April 15, 2009]
Simplified error handling in pngread.c and pngwrite.c by putting
the new png_read_cleanup() and png_write_cleanup() functions inline.
Version 1.4.0beta56 [April 25, 2009]
Renamed "user_chunk_data" to "my_user_chunk_data" in pngtest.c to suppress
"shadowed declaration" warning from gcc-4.3.3.
Renamed "gamma" to "png_gamma" in pngset.c to avoid "shadowed declaration"
warning about a global "gamma" variable in math.h on some platforms.
Version 1.4.0beta57 [May 2, 2009]
Removed prototype for png_freeptr() that was added in libpng-1.4.0beta24
but was never defined (again).
Rebuilt configure scripts with autoconf-2.63 instead of 2.62
Removed pngprefs.h and MMX from makefiles
Version 1.4.0beta58 [May 14, 2009]
Changed pngw32.def to pngwin.def in makefile.mingw (typo was introduced
in beta57).
src/Source/LibPNG/CHANGES view on Meta::CPAN
Added a request in the manual that applications do not use "png_" or
"PNG_" to begin any of their own symbols.
Changed PNG_UNUSED to "(void)param;" and updated the commentary in pngpriv.h
Version 1.5.1 [February 3, 2011]
No changes.
Version 1.5.2beta01 [February 13, 2011]
More -Wshadow fixes for older gcc compilers. Older gcc versions apparently
check formal parameters names in function declarations (as well as
definitions) to see if they match a name in the global namespace.
Revised PNG_EXPORTA macro to not use an empty parameter, to accommodate the
old VisualC++ preprocessor.
Turned on interlace handling in png_read_png().
Fixed gcc pendantic warnings.
Handle longjmp in Cygwin.
Fixed png_get_current_row_number() in the interlaced case.
Cleaned up ALPHA flags and transformations.
Implemented expansion to 16 bits.
Version 1.5.2beta02 [February 19, 2011]
src/Source/LibPNG/CHANGES view on Meta::CPAN
Removed whitespace from the end of lines in all source files and scripts.
Version 1.6.0beta16 [March 6, 2012]
Relocated palette-index checking function from pngrutil.c to pngtrans.c
Added palette-index checking while writing.
Changed png_inflate() and calling routines to avoid overflow problems.
This is an intermediate check-in that solves the immediate problems and
introduces one performance improvement (avoiding a copy via png_ptr->zbuf.)
Further changes will be made to make ICC profile handling more secure.
Fixed build warnings (MSVC, GCC, GCC v3). Cygwin GCC with default options
declares 'index' as a global, causing a warning if it is used as a local
variable. GCC 64-bit warns about assigning a (size_t) (unsigned 64-bit)
to an (int) (signed 32-bit). MSVC, however, warns about using the
unary '-' operator on an unsigned value (even though it is well defined
by ANSI-C to be ~x+1). The padding calculation was changed to use a
different method. Removed the tests on png_ptr->pass.
Added contrib/libtests/tarith.c to test internal arithmetic functions from
png.c. This is a libpng maintainer program used to validate changes to the
internal arithmetic functions.
Made read 'inflate' handling like write 'deflate' handling. The read
code now claims and releases png_ptr->zstream, like the write code.
