Blog 19/07/2010 Update libpng has been updated in Debian's stable branch. Several vulnerabilities were fixed. I've updated the Linux and Windows static binaries. 18/07/2010 Releasing new aaphoto version: v0.38 - some minor bugfixes For more information see the changelog 10/05/2010 Releasing new aaphoto version: v0.37 - OpenMP support added for multi processing - bugfix: exif info was missed out after last version's change in JPEG handling - new aaRGB v0.61 version with OpenMP support For more information see the changelog 05/05/2010 OpenMP and performance distribution I've added OpenMP support to my code and mostly i succeeded to make all time intensive parts paralleled except the image decoder and loader external libs, plus solved the shared memory access between the active separate threads. GCC supports OpenMP from version 4.2, Debian has it too in the stable branch. I'll be able to compile Windows binary with OpenMP support only after the upcoming release of Mingw GCC version 4.4. A test has been made to show the performance distribution of aaphoto on an IBM x3950 m2 server with 24 physical cores with a 460 Mpixel image. The test shows clearly that the color adjusting part scales linearly just nice when increasing the number of CPU cores. Thanks to Zsolt Bartos-Elekes (Müszi) for the test. A detailed PDF is available with a text file with the raw datas. According to the huge change in the code structure, i need a profound testing. I gladly take any help or bug report. 05/05/2010 Binaries for development version I made static binaries compiled from the current development version available on the site for user request. They can be found on the download part under the source codes. I got several requests regarding this, because the newest version can always be seen in the changelog file that has not been released yet. Avalilable for Linux and Windows platforms. Remarks: these versions need further massive testing, therefore the chance for a malfunction is rather higher, and they can even be changed daily. 18/04/2010 Update libjasper has been updated in Debian's stable branch. A denial of service type of vulnerability was fixed together with a jpeg reading error. I've updated the Linux and Windows static binaries (v0.36.3). 11/04/2010 Update libpng has been updated in Debian's stable branch. Several vulnerabilities were fixed. I've updated the Linux and Windows static binaries (v0.36.2). 16/03/2010 Releasing new aaphoto version: v0.36 - bugfix: it doesn't ask for administrative privileges anymore while running in an admin account under vista and windows 7 (windows platform only) Accidentally i left a registry hack in the innosetup config file that didn't solve anything and i also forgot about it, but it caused problems on vista and above. Finally i removed it. - bugfix: --rotate180 switch didn't turn the middle line in images with odd heights I wrote a script for testing that throws random input switches and values to aaphoto where the failure came out at once. - JPEG format handling entirely rewritten to be able to handle extra parameters in this format separately, now libjpeg is called directly instead of libjasper for reading / writing JPEG images so libjpeg is a new dependency from now on, formerly only libjasper was depended on it This was needed to restore the DPI value. - original DPI values of images are restored in BMP, JPEG and PNG formats during conversion This was a feature request from a user. It might do good in keeping print sizes of posters and photos. For more information see the changelog 01/03/2010 Update - bugfix: fix for tmpfile() patches of libjasper and libjpeg (windows platform only), when running more than one instances of aaphoto at a time, they all used the same temporary files and therefore the images became corrupt Now fixed and the windows static binary is updated too. It is marked v0.35.2. Thanks to Bill Yotter for reporting it. 27/02/2010 Releasing new aaphoto version: v0.35 - bugfix: possible buffer overflows fixed Under UHU system's development branch with GCC version 4.4.2 the compiler dropped warnings that helped to find out the fault. It recognized that within the cycle the value of the index used for the array can exceed the declared one. Thanks to Rezső Páder for the contribution. 19/02/2010 Releasing new aaphoto version: v0.34 - update: changes in new version of libpng 1.4.0, aaio.c updated as necessary png_check_sig() function replaced with png_sig_cmp(), setjmp(png_ptr->jmpbuf) has been deprecated, changed to setjmp(png_jmpbuf(png_ptr)) See more at libpng's website 14/02/2010 Update - bugfix: Restricted users could not read and write JPEG format images on Windows platform. The rest of the formats worked fine. The source of the problem was the tmpfile() C function call used by libjpeg and libjasper. This function is implemented on Windows platform that every temporary file is to be created in the root of the current directory. However the restricted users usually do not have the permissions to write there. Now fixed and the static binaries are updated too. This doesn't mean a newer program version, so it is marked v0.33.2. 12/02/2010 Update The static binaries are compiled from now with libs from the current Debian stable branch. The updates can be downloaded from here. Besides, I've finished releasing binaries for OpenBSD, OpenSolaris and Mac OS X platforms. 10/01/2010 Releasing new aaphoto version: v0.33 - some changes in documentation - bugfix: unfreed space caused memory leak - bugfix: uninitialized variable caused --resize to misbehave - fix: change of return values in procedures to reflect standard exit codes For more information see the changelog Thanks to Gábor Nagy for the MacOSX compilation. 25/10/2009 Some updates in documentation I have updated the manual files of the debian package, plus some descriptions in the sources too. Thanks to Rezső Páder for the manual. 20/10/2009 Releasing new aaphoto version: v0.32 - new option switches - new aaRGB v0.60 version: gamma handling of the lighter colors has been removed from the two-pole gamma computing, because it proved to be inefficient For more information see the changelog Thanks to Gábor Nagy for the MacOSX compilation. 24/08/2009 Releasing new aaphoto version: v0.31 - bugfix: __BMP_ONLY__ directive fix in source code - bugfix: writing of BMP images could result in corrupt BMP structure - code cleanup in BMP write function - parameters of switches also work with spaces between them - new aaRGB version v0.59 with some more code cleanup For more information see the changelog Thanks to Gábor Nagy for the MacOSX compilation. 04/07/2009 Updated MacOSX binary Non-static, stable 32 bit PPC compilation. Exclusive dependencies: libm, libc. Thanks to Gábor Nagy for compiling it. 01/03/2009 Updated Opensolaris binary I have compiled aaphoto with Sun's own compiler, so this means the Opensolaris binary does not have the libgcc dependency anymore. I have also updated the compiler scripts, so it compiles fine on Opensolaris with the method described in the INSTALL file, only the ss-dev package needs to be installed on the system. 22/02/2009 Releasing new aaphoto version: v0.30 - Implementation of PNG format (RGB and Gray images read / write with alpha channel support) - bugfix: reading corrupt exif info in JPEG files could get into an infinite loop - bugfix: length of exif info was determined wrongly - new option switches - new aaRGB version v0.58 with lots of code cleanup For more information see the changelog Thanks to Rezső Páder for his patches, the manual, fixes and ideas. The Mac OS X platform version is still in progress, currently the former version is available yet. 01/02/2009 New aaphoto release soon I'm planning to release a new version within a couple of weeks. Main changes will be the implementation of the PNG format with alpha channels, plus bugfixes and code cleanups. Currently a working version is ready and it seems to work just fine with a custom compiled JasPer lib. Only it gives a segmentation fault with the distributions' officially shipped JasPer library while writing out a JPEG file. I couldn't solve this yet. If anyone feels to help testing, an always current development version can be downloaded from here that contains not only the source codes but compiling scripts and other files too. 20/08/2008 aaphoto PNG format I've cleaned up the mess among my source files and scripts and got prepared to implement the PNG file format. 18/02/2008 aaphoto windows installer updated The windows installer had wrong version number that has been fixed finally. The updated package can be downloaded from here 14/02/2008 aaphoto debian package The debian package has been finally made. 12/02/2008 aaphoto source files changed - From now (v0.29) the source files contain the necessary configuration files, so it can be compiled the standard way: ./configure && make && sudo make install 02/02/2008 Releasing new aaphoto version: v0.29 - Grayscale images can also be used as an input - change: file name buffer increased (for processing files in folders) - Exif meta information is now restored during conversion in JPEG images For more information see the changelog Thanks to Rezső Páder for creating hungarian and english manual and for the rest of the help. 18/08/2007 MacOSX platform version Non-static, stable 32 bit i386 compilation. Exclusive dependencies: libm, libc. Thanks to Csaba Mártha for compiling it. 11/08/2007 Releasing new aaphoto version: v0.28 - bugfix: removing extra slashes from the end of folders - new aaRGB version v0.57 - overexposure propblem at contrast adjusting fixed - oversaturated colors problem at saturation adjusting fixed 18/07/2007 FreeBSD platform version Static, stable 32 bit i386 compilation. 04/07/2007 Changing license type from GPL 2 to GPL 3 The Free Software Foundation has finally released the GNU General Public License version 3 on 29 june, 2007.
