Jim Spath. Changes from previous version include: + Version 1.6.3 corrects a memory leak in gd_png.c. This leak caused a significant amount of memory to be allocated and not freed when writing a PNG image. + Version 1.6.2 from John Ellson adds two new functions: gdImageStringTTF gdImageColorResolve + Version 1.6.1 incorporates superior PNG reading and writing code from Greg Roelofs, with minor modifications by Tom Boutell. + Version 1.6 features the following changes: Support for 8-bit palette PNG images has been added. Support for GIF has been removed. This step was taken to completely avoid the legal controversy regarding the LZW compression algorithm used in GIF. Unisys holds a patent which is relevant to LZW compression. PNG is a superior image format in any case. Now that PNG is supported by both Microsoft Internet Explorer and Netscape (in their recent releases), we highly recommend that GD users upgrade in order to get well-compressed images in a format which is legally unemcumbered. + Version 1.5 featured the following changes: New GD2 format Re-arranged source files Extended I/O capabilities. Better support for Lincoln Stein's Perl Module Added functions + Version 1.4 features the following changes: Fixed polygon fill routine (again) Support for alternate data sources Support for alternate data destinations More tolerant when reading GIFs |
