Where are the PowerPC datatypes on the OS 3.9 CD?
Due to the extremely tight deadline required to ship OS 3.9 by December 4th, only the picture.datatype is currently available for the PowerPC (and none of it’s sub-classes are PPC-enabled): AmigaOS3.9:OS-Version3.9/Workbench3.9/Classes/Datatypes/picture.datatype (82,264 bytes). This is a ‘fat’ binary, meaning it contains both 68k and PPC code, and will automatically use the fastest processor available. For other PPC datatypes, simply search any Aminet mirror for “warpjpeg”, “warppng”, and “warpgif”. [David Rey/Remco Komduur] The OS 3.9 picture.datatype offers a new scaling feature, and far better dithering (not really a concern unless you use 8-bit screens), and uses the PPC only for dithering or scaling, so you need to consider whether you’re likely to use those features–if not, then it would be better to stick with the CyberGraphX one, simply because it’s faster. [Oliver Roberts] Stephane Guillard recommends installing at least the warpjpeg datatype if you have a PPC card.
