* Upgraded cexcept to version 2.0.1. * Added a configure script, to be used instead of unix-secure.mak. * Fixed a build issue that occured when using libpng from the system. * Fixed processing when image reduction yields an output larger than the original. * Fixed behavior of -preserve. * Removed displaying of partial progress when abandoning IDATs under the -v option. The percentages displayed were not very accurate. Changes 0.6: * Upgraded libpng to version 1.2.29-optipng [private] * Implemented grayscale(alpha)-to-palette reductions. * Improved conversion of bKGD info during RGB-to-palette reductions. * Fixed conversion of bKGD and tRNS during 16-to-8-bit reductions. * Added support for compressed BMP (incl. PNG-compressed BMP, you bet!) * Improved the speed of reading raw PNM files. * Recognized PNG digital signatures (dSIG) and disabled optimization in their presence, to preserve their integrity. * Allowed the user to enforce the optimization of dSIG'ed files. * Recognized APNG animation files and disabled reductions to preserve their integrity. * Added the -snip option, to allow the user to "snip" one image out of a multi-image file, such as animated GIF, multi-page TIFF, or APNG. * Improved recovery of PNG files with incomplete IDAT. * Fixed a crash triggered by the use of -log on some platforms. * Fixed behavior of -out and -dir when the input is already optimized. * Provided more detailed image information at the start of processing. * Provided a more detailed summary at the end of processing, under the presence of the -v option and/or the occurence of exceptional events. |
