Dear Mathematica users, the new Import[]/Export[] filter for Portabel Network Graphics is finished. It integrates seamless into Mathematica's Import[]/and Export[] functions and PNG bitmaps can now be read and written. Additional to the standard converters it allows the reading and writing of bitmaps with an alpha-channel used for transparence and the manipulation of PNG's with 16 bit bit-depth. Almost all web browser support PNG images, and my OpenGL viewer for Mathematica can use PNG images as textures. More information about PNG's can be found at http://www.libpng.org/pub/png/ more informations about the OpenGL viewer with useful examples of textures on 3d surfaces can be found at http://phong.informatik.uni-leipzig.de/~kuska/mathgl3dv3/ Until MathSource update it's items the packages for MS-Windows and Unix (Linux, SGI) can be found at http://phong.informatik.uni-leipzig.de/~kuska/mcpng.html The package come with the full source code for the MathLink converter and the small interface Mathematica code. Many thanks to Paul Hinton from WRI that answer all my bothering questions about Experimental`RegisterConverter[] Enjoy the package Jens
