I think you tried to send me a message re: the animation query I posted to comp.windows.x. I've appended what I received below. If you can remember what you typed, I'd appreciate another attempt!

Hi, I'm new to this group so please bear with me!  Two years ago I wrote a Sunview application for fast animation of raster files. With Sunview becoming rapidly obselete, I've finally decided to rewrite everything from scratch in XView. I put together a quick test, and I've found that XPutImage() is considerably slower (factor of 2 on average?) than the Sunview command pw_rop() which moves image data from memory pixrects to a canvas. This was on a Sparc IPX. It seems that: (1) the X protocol communication is slowing things down; or (2) XPutImage is inefficient...or both! My question is, what is the fastest way in X11R5 to dump 8 plane image data to a window? Can I take advantage of the fact that the client is running on the same machine as the server? Or am I stuck with XPutImage() (in which case I might as well give up now...)?  All help appreciated...thanks!  Derek  ----------------------------------------------------------- | Derek C.
