Is there an extension to the X Server available that supports the oversampling (and undersampling) of pixels? The corresponding "Xlib" call might be a variant on XPutImage: XZoomImage(display, drawable, gc, image, src_x, src_y, dst_x, dst_y, width, height, xfactor, yfactor ) xfactor and yfactor would be the integer replication factors. Factors greater than 1 would zoom an image, factors less than -1 would dezoom an image (0,-1, and 1 would be defined to have no effect). If so, where might it be available, and any impressions on the difficulty of integrating an extension into our server? Thanks. Scott E. Johnston Advanced Decision Systems Mt.
