In order to implement your StretchImage(), the process would look something like: XRenderCreatePicture(window) XCreatePixmap() XRenderCreatePicture(pixmap) # If the input size is constant, the above only need to be done once XRenderSetPictureTransform(pixmap_picture) # The above line is only needed when the amount of stretch changes XPutImage(pixmap) # XImage struct used here XRenderCompositeImage(pixmap_picture, null_mask, window_picture) # Free pictures and pixmap here, unless cached Setting a non-default filter to smooth out the scaling is left as an exercise for the reader.
