Anybody know where I can find some info on programming AGA graphics in C? I'm converting a program from a 640 x 200, 16 color screen to 256 colors. I assume the bitplanes are handled the same way, as the BitMap struct is designed for up to 8 planes. But I don't know how to handle the colors. What functions replace GetRGB4(), LoadRGB4(), etc?

Get the Autodocs. 'Tis folly to try to program without them.

Vic, thanks for answering, but where do you get the Autodocs? As far as I know, they're not yet availble from CBM or Addison Wesley Publishing.

The autodocs are always available on disk long before they are printed. Most serious programmers rarely use the printed versions because they are always out of date. Disk autodocs are available to US registered developers through CATS, for other countries, see your local (country) Commodore tech support organization.

I thought the reason for using online autodocs was so you could search them electronically!!! ;-}

Thanks, but I was hoping to get the info without registering as a developer. I registered as a junior (cheaper) developer last year, and didn't feel I got my money's worth. The full developer status is abou $ 600 per year, and for what I do, it's just not worth it. I think the IBM and Mac worlds are much friendlier to developers. Anyway, this is not the place to rag on about Commodore! Thanks for your reply. I'll probably have to wait for the printed stuff.

Yup, paying that cash is the only way to get stuff from CBM. I've been paying it for years, and I agree, every single year I've balked at paying it again. Given CBM's present straits, it makes even less sense. Do what they do in the PC world: go to the third party, public sources of info, like the Amiga manuals you can buy in the store, and public domain source code examples.

I don't mind paying for information, but there's nothing available yet from third parties, and the PD source code examples I've found are assembler, and don't give any info on library calls. eg. LoadRGB4() is the old call to load the color registers, and I'd like to know the new call (LoadRGB8() ???), and a few simple things like that. I guess I'll have to keep looking, or wait till something is published. Thanks for taking the time to answer my message. Jon /exit

You can get anything/everything you need from CATS as a certified developer. Have you contacted them? Also, have you looked in Library 10 at … AGA.LHA/Bin Bytes: 34892, Count: 45, 28-Nov-93 Title : Spec and doc for programming the AGA chipset Keywords: AGA AA GRAPHICS DOC Specification and documentation for programming the AGA chipset. -and- HOWTO.LHA/Bin Bytes: 139187, Count: 56, 26-Jul-93 Title : HowToCode, friendly hardware programming, AGA Keywords: AGA ASM CODE COMRADEJ DEMO HACK HOWTO This is a document on "friendly" hardware programming (for those of you who must do it).

Lots of good information. -sja
