I asked about this a month or so ago, and didn't get any response, so here goes again... Does anyone have any info whatsoever on Amiga frame buffers? I'm looking for true color... that's at least 24 bits/pixel. More would be great. Higher resolution would be nice but the color space is more important to me. I know none are out now, but does anyone know who's working on them? Help! Oh yeah, I saw NewTek's Toaster (at AmiExpo), as well as Mimetics' product (at SIGGRAPH), but they seem to be NTSC only (correct me if I'm wrong, please!). This is for professional image processing applications, so NTSC isn't good enough... I need RGB. Thanks in advance....

Well, yes, there are 'frame buffers' that work in the Amiga 2000. The nicest one is called the Targa Board from AT&T. The secret is you buy a bridge board, write a little program on the PC side to pick up messages from the Amiga, and then manipulate the display. You probably only need LoadImage(), SaveImage(), ReadPixel(), and WritePixel(). [As a note to Bridge card owners and/or Commodore, something that talked to message ports would be really nice here. Maybe a named port 'BridgePort' that you could send messages to, and a PC TSR program that users programs could poll/send messages to.] One reason why I sometimes reccomend the 2000 over the 500 is that there are these really exotic boards (not that frame buffers are exotic) that work on the PC bus. The other nice feature of this is that you can get the PC to convolve the image or whatever with it's use of the 8087 it could do so more rapidly than the 68000 could. Plus you get the benefits of multiprocessing. --Chuck McManis uucp: {anywhere}!sun!cmcmanis BIX: cmcmanis ARPAnet: cmcmanis@sun.com These opinions are my own and no one elses, but you knew that didn't you.

Please add me to the "distribution list". 512 x 512 not absolutly required but true color is. E-mail: wucs2.umree.UUCP.deh (I think. Please reply to net also if you try this so I'll know if it was unsuccessful) U-snail: David E.
