Is there any support for TIFF files on a GS? I have a VOC to which I would somehow like to send a captured screen file( say from the VOC itself or an opened TIFF file). There seems to be 2 issue here: frame grabbing( does this exist?) on the GS with support for the VOC and support for TIFF files. Ideally I'd like the TIFF files to end up as 640x400 images. Also, is there something that will sync a voice/sound file to a "slide show" created using the VOC? Finally, what about support for 3200 pics in SHR( for the VOC)? One of the things I am trying to do is to take 40 " pictures" created elsewhere( say a Mac-PICT2, or a NeXT-TIFF) and use the VOC to piece together a lecture, with HyperStudio,or otherwise, controlling the timing and fades between pictures. A real bonus would be to be able to have the GS speak some overlayed tidbits on each slide, when pointing to them. Philip McDunnough University of Toronto philip@utstat.utoronto.ca

It overlays a video signal onto the computer's video signal; it does not internalize the video signal into IIgs graphics form. There are a couple of good digitizer cards available for the IIgs (Scott Gentry of AOL wrote the software for one of them), but the VOC is not one of them.

Well I've now repeated you suggested request a couple of thousand times. Hope that suffices.I realize that it is not a frame grabber. What I am trying to find is one that works together with the VOC. I am also trying to see to what extent various graphics' modes are capable of being supported either by the GS or perhaps a graphics' card in slot 4 with a 12.27MHz dot clock. Clearly such a graphics card with a VOC would be able to make use of the VOC's capabilities. The 12MHz clock was chosen in order to obtain square pixels. >There are a couple of good digitizer cards available for the IIgs (Scott >Gentry of AOL wrote the software for one of them), but the VOC is not one >of them. Sorry. I take it these are the ones which use Allison, however they do not appear to work with the VOC. I am very interested in VOC+frame grabber, VOC alone, frame grabber alone,graphics card alone or in combination with the above, and supporting software. Thank's for the info.

You didn't say that, you just said you wanted to frame grab with the VOC. This alone is not possible. Now are you looking for something that's specifically designed to work with the VOC, or just a stand-alone product that's VOC compatible? Do you want to run the video signals through the VOC and out to the digitizer? I still don't understand what you're asking for. (I don't have any further information on it anyway, but your specific request might trigger someone's memory.) -- ============================================================================ Matt Deatherage, Developer Technical | The opinions expressed herein are Support, Apple Computer, Inc. | not those of Apple Computer, and Personal mail only, please.

Do you want to >run the video signals through the VOC and out to the digitizer? I still >don't understand what you're asking for. Let me try to be clearer. I'm new at this video stuff so much of the stuff is vague in my own mind. I believe what I want is the following: There is a digitizing board called Visionary GS which operates with software called Allison. There may very well be other boards out there, and I'd appreciate any information w.r.t these. Now input a picture into the VOC from say a video camera. This then apparently gives you a 640x400 image on the GS RGB monitor, and it's an extremely nice one. Now the question is whether or not the digitizer can grab this image and either save it as a TIFF or other file format( eg.3200 colour picture). That's the first part. The second is whether or not the digitizer can grab the 640x400 picture, save it, and then output it via the VOC as a 640x400 picture. The reason I keep stressing 640x400 is that the picture clarity using the GS colour monitor and a VOC is outstanding. So ideally it would be nice to have a product designed to work with the VOC, but I would settle for a stand-alone one which was VOC compatible. >(I don't have any further information on it anyway, but your specific request >might trigger someone's memory.) >Matt Deatherage, Developer Technical | The opinions expressed herein are >Support, Apple Computer, Inc. | not those of Apple Computer, and >Personal mail only, please.

You don't "input" a standard video picture into the VOC. That implies that the VOC has a digitized copy of the picture in memory. It does not. It's simply displaying that video signal mixed with the computer's video signal. The computer has absolutely no access to that picture in pixels or any other computer-graphics kind of way. If you want to digitize the picture, you'll have to feed the same video signal to a digitizer (like Visionary) and tell it to digitize. -- ============================================================================ Matt Deatherage, Developer Technical | The opinions expressed herein are Support, Apple Computer, Inc. | not those of Apple Computer, and Personal mail only, please.

It was too slow for video work, but he hooked a camera up and if you didn't move for 5 seconds you had a scanned picture in Paintworks Gold format. The camera had to be returned and the software he wrote is copyrighted by the school (as are all thesis projects), but I will see if he has remained in the Apple II world and get him to post his notes.

Boy, this hasn't been an easy month... If this message shows up repeatedly, please accept my most humble apologies. On to the issues at hand... Over the Memorial Day weekend, I performed testing on digitizing using the Enhanced Vision Plus/VisionaryGS and the VOC. As I suspected, there was complete hardware compatibility, however there are problems when digitizing the output of the VOC. When digitizing the output of the VOC, you'll get "The Incredible Shrinking Window Syndrome". Turns mirrors so the reflective surfaces oppose each other and you'll have the same effect. This effect is most pronounced in Full Screen monochrome mode. What can be done about TISWS? Three things. 1. Don't digitize the output of the VOC. 2. Use an electronic A/B switch installed in the video input line before the VOC. 3. Wait for me to come up with a software work-around. Of the three choices above, I prefer number 3. I'm not entirely sure number 3 is doable, though. I have ordered the VOC developers doc from Apple in an effort to find a way to disable Overlay by switching Video Input to Video Output. I've tried some other things already (such as disabling the VOC) but it seems to want to overlay as long as there is video present on the input. There would seem to be a solution for this because Digital Vision built -one- prototype digitizer for the Apple II Video Bus (or whatever it's called). AE is also rumored to have been developing one for the bus but stopped in mid cycle. I mention this because if someone from Apple knows how to do what I'm trying to do, I wouldn't be too ashamed to accept an answer (either here or via AppleLink) -- if you do reply to me, use THIS address... scott@brnded.ne1300.ingr.com I say use this ^^^^ address because this system is very busy.
