If you use Batik to do the rasterization, it already has a Base64OutputStream which if given to the PNGTranscoder will 'on the fly' convert the binary PNG stream into a Base64 stream suitable for inclusion in the e-mail.

Also PNG does real transparency and can go to 24/32bit not just pallette. ----- To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click "edit my membership" ---- Yahoo!
