hi,
im trying to add a comment field to a gif file. i dont want to re-encode it, just add to it.

i was using org.w3c.dom.*; nodes, imageIO and IIOImage to do this with png's but because of licencing fees that would need to be paid to Unisys (i presume this is the reason) the imageIO doesnt support writing to gif's, only reading them.

do you know of any 'non-third party' software that sorts out any CRC checking and length checking for you?

thanks

dex
