aaphoto v0.41 - new aaRGB v0.64 version update (see aaRGB changelog) 6 - add -- switch to mark the end of option list for posix compatibility 7 - fix some warnings given by -Wextra compile option 82010/12/18 - aaphoto v0.40 - new aaRGB v0.63 version update 9 - fix some warning messages during build 10 - some changes in documentation 11 - error message when --verbose switch is used with no other ones to avoid misunderstanding 12 that other switches are still needed (aaphoto -V file) 132010/09/14 - aaphoto v0.39 - new aaRGB v0.62 version update 14 - bugfix: an ugly misconception in my paralleled code caused weird behavior when using more threads 15 - bugfix: BMP image writer function didn't zero out the BMP align bytes in file buffer 16 therefore the same output differed in some cases 17 - bugfix: PNG image reader function stored the unreliable values of pixel resolution 18 when the type was unknown 19 - rewrite the code to suffice the ISO C90 ANSI standard C form (GCC -pedantic option) 20 - new windows platform patch of libjasper for static build to replace mkstemp() function call 21 because it is not yet supported under MinGW 22 - some changes in documentation 23 - new default LDFLAG -lgomp for OpenMP 24 - update all build scripts for Debian 6 platform 252010/07/18 - aaphoto v0.38 - add verbose message showing presence of alpha channel in PNG images 26 - bugfix: fix compile with only BMP support 27 - fix some warning messages during build 28 - remove unnecessary __WIN32__ macro 292010/05/10 - aaphoto v0.37 - add OpenMP support for multi processing, all possible time intensive codes paralleled 30 __OPENMP__ directive and -fopenmp option are needed at compile time (supported since GCC v4.2) 31 (not available on windows platform yet) 32 - new -t, --threads switch added to manually set the number of working threads 33 - new aaRGB v0.61 version update 34 - bugfix: exif info was left out after last version's change in JPEG handling 35 - improve exif handling and verbose messages 36 - refine additional verbose messages 37 - remove pgx file type support because it is outdated 38 - some changes in documentation 39 - some minor code cleanup and bugfixes 402010/03/16 - aaphoto v0.36 - bugfix: fix for tmpfile() patches of libjasper and libjpeg (windows platform only) 41 when running more than one instances of aaphoto at a time 42 they all used the same temporary files and therefore the images became corrupt 43 - bugfix: it doesn't ask for administrative privileges anymore while running in an admin account 44 under vista and windows 7 (windows platform only) 45 - bugfix: the --rotate180 switch didn't turn the middle line in images with odd heights 46 - rewrite JPEG format handling entirely to be able to handle extra parameters in this format 47 separately, now libjpeg is used directly instead of libjasper for reading / writing JPEG images 48 so libjpeg is a new dependency from now, formerly only libjasper was depended on it 49 - restore original DPI values of images in BMP, JPEG and PNG formats during conversion 50 - refine program messages 51 - print the time elapsed in seconds since program start in verbose mode if not zero 52 - print extra infos of bitmap dimension, resolution and color depth in verbose mode 532010/02/25 - aaphoto v0.35 - bugfix: possible buffer overflows fixed 542010/02/19 - aaphoto v0.34 - __UNIX__ macro removed from Makefile, not needed anymore 55 - bugfix: static binary update with patches of libjasper and libjpeg 56 1) sleep() function missing on mingw32 platform 57 2) bad implementation of tmpfile() function on windows platform 58 it tries to create temporary files in the root of current directory 59 instead of the system temporary path so that causes failure for unprivileged users 60 who don't have permissions to write there 61 - update: changes in new version of libpng 1.4.0, aaio.c updated as necessary 62 png_check_sig() function replaced with png_sig_cmp() 63 setjmp(png_ptr->jmpbuf) has been deprecated, changed to setjmp(png_jmpbuf(png_ptr)) 64 see more at http://www.libpng.org/pub/png/src/libpng-1.2.x-to-1.4.x-summary.txt 652010/01/10 - aaphoto v0.33 - some changes in documentation 66 - bugfix: unfreed space caused memory leak 67 - bugfix: uninitialized variable caused --resize to misbehave 68 - fix: change of return values in procedures to reflect standard exit codes 69 now it has a sense to run something like "aaphoto image.jpg && echo OK" 70 formerly return codes meant opposite 71 - fix a warning message during compile time, an include was missing 72 - boundary check of fixed size arrays added for safety reasons 73 - the --speed switch removed, it made the code less platform independent and was fussy anyway 74 - error messages printed to stderr instead of stdout from now 75 - more verbose error messages on failure of image load 762009/10/18 - aaphoto v0.32 - new aaRGB v0.60 version update 77 - new --noexif switch added to save new image without exif info 78 -

aaphoto v0.30 - implement PNG format (RGB and Gray images read / write with alpha channel support) 86 - bugfix: reading corrupt exif info in JPEG files could get into an infinite loop 87 - bugfix: length of exif info was determined wrongly 88 - rework of the parameters and switches parsing part 89 - lots of code cleanup 90 - most of the comments in code translated to english 91 - print messages get flushed out with fflush now during process 92 - the --info switch removed 93 - the -o switch removed for safety reasons, --overwrite still available 94 - the -h switch added for unix compatibility 95 - the -j1 and -j2 switch removed, --jpg and --jp2 still available 96 - the --png switch is now new for PNG output 97 - the -s switch changed from --speed to --silent for compatibility 98 - the --mute switch changed to -s, --silent and --quiet for unix / posix compatibility 99 - the -V, --verbose switch is now new for more detailed output during image process 100 - the --test switch now turns the --autoadjust switch on by default 101 - the -d, --description and -l, --license switches removed 102 -
