Hi All! I have almost finished a library I've been working on for low these many weeks, and I need some help. I was sticking in some routines for saving specified screens in IFF format and other routines for displying such images. However, I can't find the accepted way for indicating that the image is in HAM or EHB mode. I could assume 6 bit planes = HAM but this would be a TERRIBLE thing to have to do!!! Sould I send in for more recent IFF docs? Of course, if someone could mail me his/her sources for such things I would be ETERNALLY GRATEFUL. My present coding is built around the code from the IFF disk... (Argh). Oh yes, I should have the object code library (Lattice) ready for release in under a month. The sources will be about 200K. (Up to 180K now.) The docs will be the hardest part.

My present coding is built >around the code from the IFF disk... (Argh). The HAM, EHB, or Dual Playfield information should be stored in a "CAMG" chunk, which is specific to the Commodore Amiga. This is a LONG "Amiga Viewmode". This chunk is also used for properly storing the "overscan" or PAL/NTSC size. An example of proper use is in the ScreenSave program by Carolyn Scheppner included in the latest IFF disk from CATS. Also some extra information on changes to that document is available on page 4 of the September/October issue of AmigaMail. -- Marco
