On read invert alpha, processing - occurred after shift processing, which causes the final values to be - outside the range that should be produced by the shift. Reversing the - order on read makes the two transforms work together correctly and mirrors - the order used on write. - Do not read invalid sBIT chunks. Previously libpng only checked sBIT - values on write, so a malicious PNG writer could therefore cause - the read code to return an invalid sBIT chunk, which might lead to - application errors or crashes. Such chunks are now skipped (with - chunk_benign_error). - Make png_read_png() and png_write_png() prototypes in png.h depend - upon PNG_READ_SUPPORTED and PNG_WRITE_SUPPORTED. - Support builds with unsupported PNG_TRANSFORM_* values. All of the - PNG_TRANSFORM_* values are always defined in png.h and, because they - are used for both read and write in some cases, it is not reliable - to #if out ones that are totally unsupported. This change adds error - detection in png_read_image() and png_write_image() to do a - png_app_error() if the app requests something that cannot be done - and it adds corresponding code to pngimage.c to handle such options - by not attempting to test them. - Moved redefines of png_error(), png_warning(), png_chunk_error(), - and png_chunk_warning() from pngpriv.h to png.h to make them visible - to libpng-calling applications. - Moved OS dependent code from arm/arm_init.c, to allow the included - implementation of the ARM NEON discovery function to be set at - build-time and provide sample implementations from the current code in the - contrib/arm-neon subdirectory. The __linux__ code has also been changed to - compile and link on Android by using /proc/cpuinfo, and the old linux code - is in contrib/arm-neon/linux-auxv.c. The new code avoids POSIX and Linux - dependencies apart from opening /proc/cpuinfo and is C90 compliant. - Check for info_ptr == NULL early in png_read_end() so we don't need to - run all the png_handle_*() and depend on them to return if info_ptr == NULL. - This improves the performance of png_read_end(png_ptr, NULL) and makes - it more robust against future programming errors. - Check for __has_extension before using it in pngconf.h, to - support older Clang versions (Jeremy Sequoia). - Treat CRC error handling with png_set_crc_action(), instead of with - png_set_benign_errors(), which has been the case since libpng-1.6.0beta18. - Use a user warning handler in contrib/gregbook/readpng2.c instead of default, - so warnings will be put on stderr even if libpng has CONSOLE_IO disabled. - Added png_ptr->process_mode = PNG_READ_IDAT_MODE in png_push_read_chunk - after recognizing the IDAT chunk, which avoids an infinite loop while - reading a datastream whose first IDAT chunk is of zero-length. - This fixes CERT VU#684412 and CVE-2014-0333. - Don't recognize known sRGB profiles as sRGB if they have been hacked, - but don't reject them and don't issue a copyright violation warning. - Moved some documentation from png.h to libpng.3 and libpng-manual.txt - Minor editing of contrib/arm-neon/README and contrib/examples/*.c - Fixed typos in the manual and in scripts/pnglibconf.dfa (CFLAGS -> CPPFLAGS - and PNG_USR_CONFIG -> PNG_USER_CONFIG). - Un-deprecated png_data_freer(). +Changes since the last public release (1.6.10): + + Use "if (value != 0)" instead of "if (value)" consistently. + Changed ZlibSrcDir from 1.2.5 to 1.2.8 in projects/vstudio. + Moved configuration information from the manual to the INSTALL file. + Removed #if/#else/#endif from inside two pow() calls in pngvalid.c because + they were handled improperly by Portland Group's PGI-14.1 - PGI-14.3 + when using its "__builtin_pow()" function. + Silence 'unused parameter' build warnings (Cosmin Truta). + $(CP) is now used alongside $(RM_F).

Prepending a prefix to exported symbols + +Starting with libpng-1.6.0, you can configure libpng (when using the +"configure" script) to prefix all exported symbols by means of the +configuration option "--with-libpng-prefix=FOO_", where FOO_ can be any +string beginning with a letter and containing only uppercase +and lowercase letters, digits, and the underscore (i.e., a C language +identifier). This creates a set of macros in pnglibconf.h, so this is +transparent to applications; their function calls get transformed by +the macros to use the modified names. + +XII. Configuring for compiler xxx: + +All includes for libpng are in pngconf.h. If you need to add, change +or delete an include, this is the place to do it. +The includes that are not needed outside libpng are placed in pngpriv.h, +which is only used by the routines inside libpng itself. +The files in libpng proper only include pngpriv.h and png.h, which +in turn includes pngconf.h and, as of libpng-1.5.0, pnglibconf.h. +As of libpng-1.5.0, pngpriv.h also includes three other private header +files, pngstruct.h, pnginfo.h, and pngdebug.h, which contain material +that previously appeared in the public headers. + +XIII. Removing unwanted object code + +There are a bunch of #define's in pngconf.h that control what parts of +libpng are compiled. All the defines end in _SUPPORTED. If you are +never going to use a capability, you can change the #define to #undef +before recompiling libpng and save yourself code and data space, or +you can turn off individual capabilities with defines that begin with +PNG_NO_. + +In libpng-1.5.0 and later, the #define's are in pnglibconf.h instead. + +You can also turn all of the transforms and ancillary chunk capabilities +off en masse with compiler directives that define +PNG_NO_READ[or WRITE]_TRANSFORMS, or PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS, +or all four, along with directives to turn on any of the capabilities that +you do want. The PNG_NO_READ[or WRITE]_TRANSFORMS directives disable the +extra transformations but still leave the library fully capable of reading +and writing PNG files with all known public chunks. Use of the +PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS directive produces a library +that is incapable of reading or writing ancillary chunks. If you are +not using the progressive reading capability, you can turn that off +with PNG_NO_PROGRESSIVE_READ (don't confuse this with the INTERLACING +capability, which you'll still have). + +All the reading and writing specific code are in separate files, so the +linker should only grab the files it needs. However, if you want to +make sure, or if you are building a stand alone library, all the +reading files start with "pngr" and all the writing files start with "pngw". +The files that don't match either (like png.c, pngtrans.c, etc.) +are used for both reading and writing, and always need to be included. +The progressive reader is in pngpread.c + +If you are creating or distributing a dynamically linked library (a .so +or DLL file), you should not remove or disable any parts of the library, +as this will cause applications linked with different versions of the +library to fail if they call functions not available in your library. +The size of the library itself should not be an issue, because only +those sections that are actually used will be loaded into memory. + +XIV. Changes to the build and configuration of libpng in libpng-1.5.x + +Details of internal changes to the library code can be found in the CHANGES +file and in the GIT repository logs. These will be of no concern to the vast +majority of library users or builders; however, the few who configure libpng +to a non-default feature set may need to change how this is done. + +There should be no need for library builders to alter build scripts if +these use the distributed build support - configure or the makefiles - +however, users of the makefiles may care to update their build scripts +to build pnglibconf.h where the corresponding makefile does not do so. + +Building libpng with a non-default configuration has changed completely. +The old method using pngusr.h should still work correctly even though the +way pngusr.h is used in the build has been changed; however, library +builders will probably want to examine the changes to take advantage of +new capabilities and to simplify their build system. + +A. Specific changes to library configuration capabilities + +The exact mechanism used to control attributes of API functions has +changed. A single set of operating system independent macro definitions +is used and operating system specific directives are defined in +pnglibconf.h + +As part of this the mechanism used to choose procedure call standards on +those systems that allow a choice has been changed. At present this only +affects certain Microsoft (DOS, Windows) and IBM (OS/2) operating systems +running on Intel processors. As before, PNGAPI is defined where required +to control the exported API functions; however, two new macros, PNGCBAPI +and PNGCAPI, are used instead for callback functions (PNGCBAPI) and +(PNGCAPI) for functions that must match a C library prototype (currently +only png_longjmp_ptr, which must match the C longjmp function.) The new +approach is documented in pngconf.h + +Despite these changes, libpng 1.5.0 only supports the native C function +calling standard on those platforms tested so far (__cdecl on Microsoft +Windows). This is because the support requirements for alternative +calling conventions seem to no longer exist. Developers who find it +necessary to set PNG_API_RULE to 1 should advise the mailing list +(png-mng-implement) of this and library builders who use Openwatcom and +therefore set PNG_API_RULE to 2 should also contact the mailing list. + +B. Changes to the configuration mechanism + +Prior to libpng-1.5.0 library builders who needed to configure libpng +had either to modify the exported pngconf.h header file to add system +specific configuration or had to write feature selection macros into +pngusr.h and cause this to be included into pngconf.h by defining +PNG_USER_CONFIG. The latter mechanism had the disadvantage that an +application built without PNG_USER_CONFIG defined would see the +unmodified, default, libpng API and thus would probably fail to link. + +These mechanisms still work in the configure build and in any makefile +build that builds pnglibconf.h, although the feature selection macros +have changed somewhat as described above. In 1.5.0, however, pngusr.h is +processed only once, when the exported header file pnglibconf.h is built. +pngconf.h no longer includes pngusr.h, therefore pngusr.h is ignored after the +build of pnglibconf.h and it is never included in an application build. + +The rarely used alternative of adding a list of feature macros to the +CPPFLAGS setting in the build also still works; however, the macros will be +copied to pnglibconf.h and this may produce macro redefinition warnings +when the individual C files are compiled. + +All configuration now only works if pnglibconf.h is built from +scripts/pnglibconf.dfa. This requires the program awk. Brian Kernighan +(the original author of awk) maintains C source code of that awk and this +and all known later implementations (often called by subtly different +names - nawk and gawk for example) are adequate to build pnglibconf.h. +The Sun Microsystems (now Oracle) program 'awk' is an earlier version +and does not work; this may also apply to other systems that have a +functioning awk called 'nawk'. + +Configuration options are now documented in scripts/pnglibconf.dfa. This +file also includes dependency information that ensures a configuration is +consistent; that is, if a feature is switched off dependent features are +also removed. As a recommended alternative to using feature macros in +pngusr.h a system builder may also define equivalent options in pngusr.dfa +(or, indeed, any file) and add that to the configuration by setting +DFA_XTRA to the file name. The makefiles in contrib/pngminim illustrate +how to do this, and a case where pngusr.h is still required. + +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.
