Re: GIF-Modification
Pete, some time ago I did use the PurpleCode library to do similar things with gif (even w/o an awt peer) http://www.purpletech.com/code.jsp Not sure if it has capabilities of 'reopening' an existing image - but it seems to be very complete...

Re: GIF Modification
Peter A colleague did this sort of thing a while back. I asked him what he had used. He said... It was Java Advanced Imaging. http://java.sun.com/products/java-media/jai/index.html I used about 0.1% of its capabilities - the main thing was that it provided a way to write images as GIFs. Most of what I used was the imaging stuff in the standard Java libraries - java.awt.image etc, which has all the stuff for setting up image buffers and drawing on them. Hope this helps.

Re: GIF Modification
WRITING GIFS. CAN'T BE HERE'S THE LATEST JAI 1.1 DOCS: o GIF file handling: GIF files are read using the JDK's internal reader. There is no GIF writer. Due to a bug in the AWT GIF decoder, GIFs with a transparent background will be decoded as if their background were black. GIF files may not be read remotely, i.e., via RemoteImage, on hosts without window system access as the reader uses the AWT toolkit which requires window system access. THERE IS NO GIF WRITER. JPEGS ? YES. -Original Message- From: A mailing list about Java Server Pages specification and reference [mailto:[EMAIL PROTECTED]]On Behalf Of Mark Lines-Davies Sent: Wednesday, March 06, 2002 6:19 AM To: [EMAIL PROTECTED] Subject: Re: GIF Modification Peter A colleague did this sort of thing a while back.
