Hi Joe,
Yeah, I concur with the analysis that you ran out of video RAM space. A
quick look at CW_ANIMATE shows that pixmaps are allocated to every
frame as that is the quickest means to animate in IDL. Video
hardware is highly optimized for operations such as these - the "TV"
routine won't even come close. I'm surprized that you got as far as you
did - how much video memory do you have? Video cards with 32M are
becoming cheaper and much more common these days and you can probably
pick one up for close to $100. However, unless I am mistaken, you
require: 500 x 800 x 180 = 72Mbytes at 256 colors. Even if you stopped
at frame 95: 500 x 800 x 95 = 38Mbytes!?
As far as the "developers looking at it" (I shudder everytime I hear
that), that means that IDL7.2 might address it. IMO, I do not think
there is a solution under the current method. I also suspect that ALL
Windows platform will exhibit the same limitations since it is not an OS
problem.
