18-Jun-2010 GBM.DLL 1.67 * Fix: gbm_guess_filetype() did only check for the first matching extension chars but not the whole extension. This resulted in reporting of .p as valid .png file for instance. Now the complete extension is checked. * TIFF codec: - Update to Libtiff 3.9.4 - Update to ZLib 1.2.5 - Finally fix longer lasting issue with libtiff 3.9.x when reading a vertically flipped YCbCr image via RGBA reader with 64bit GBM. It led to a crash due to an illegal write pointer which seems to be caused by wrongly used pointer arithmetic. Workaround is that vertical flipping is now done by GBM and prevented in libtiff. * PNG codec: - Update to ZLib 1.2.5 - Update to Libpng 1.4.2 - Integrate APNG extension patch - Add APNG support (read individual animation images) * JPEG codec: - Update to IJG 8b GBMV2 1.55 * Fix handling of file dialog when the path previously stored in profile does no longer exist. Now the current directory is used then. GBM File Dialog 1.55 * Add note about Animated PNG support to the online help * Add index parameter for PNG read options to the online help OpenJPEG codec tools 1.3.4 * Now using zlib 1.2.5 * Now using IJG JPEG 8b * Now using libtiff 3.9.4
