Hopefully IFF files will still be around then. The future is sooner than many think. It used to be there was only two types of display hardware: PAL versus NTSC. Then came the distinction of halfbrite versus no halfbrite. The 1meg Agnus chips and the A2024 monitor are available today, and the new Denise chip (for 640x480 x 4 colors) will be coming soon. > ....

I agree with Sam, any program that writes an IFF file should put in as much information as possible so that the IFF reader program (or the graphics.library) can make the best decision on how to display the file. -- Joe Smith (408)922-6220 | SMTP: JMS@F74.TYMNET.COM or jms@tymix.tymnet.com McDonnell Douglas FSCO | UUCP: ...!{ames,pyramid}!oliveb!tymix!tardis!jms PO Box 49019, MS-D21 | PDP-10 support: My car's license plate is "POPJ P," San Jose, CA 95161-9019 | narrator.device: "I didn't say that, my Amiga did!"
