A request for help:

I am using OpenWindows(X11) on a SparcStation 1+ and I'd like to display a 512x512 picture with 8-bit pixel values, but I can't find any X function which will do the trick.  Setting the color map is easy, but how do you display a row or region of pixels which is stored as, say, a char array?
It seems like using either an image or pixmap would be required, but the documentation on the formats is unclear -- if XYPixmap really requires separating all the bits out into bitplanes, that seems rather cumbersome and inefficient.

Perhaps this is a trivial question with an obvious answer.  If so, please excuse my ignorance--any help would be gratefully received.

Thanks,
Jan Martin
