Thank you! Exactly the verification I needed. Perhaps I could ask for a recommendation when it comes to a PNG to SWF batch converter as well? Seems to be quite a few out there.
Thanks again.

I am particularly interested in how the alpha channel in the > PNG is translated and stored. When you import a PNG image with an alpha channel and select it to use JPEG compression when exporting, the RGB data is saved as a JPEG, but the alpha channel is still stored as a lossless, lzw data. That means that if your image's transparency is too complex, it will still be too big, no matter what the JPEG quality you select. The only workaround possible is simplifying the transparency - basically, it's the same kind of workaround you'd apply to a grayscale GIF image... using less levels of colors, avoiding dithering, etc. - Zeh _______________________________________________ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com _______________________________________________ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
