Does anyone know if the beta David> version of GifConverter handles bad JPEG files better? I suspect GIFConverter has the same problems JPEGView does, as they both rely on QuickTime to do the decoding, and it's the QuickTime JPEG decompressor which chokes and crashes the system during decompression of bad images. I suppose a lack of thorough error checking is a price you pay to get the speed that QuickTime gives you. Returning to the color-quantization issues raised before, however -- and at the risk of giving too much away about software still in development :-) -- let me just say that JPEGView 2.0 *will* support color quantization on 8-bit (or less) systems, and it will be fast. 'Nuff said. Aaron Giles JPEGView Author a-giles@uchicago.edu
