- I am using XGetImage() to extract the pixmap of window which I am going
- to convert to other formats (like Postscript for example). However,
- when the window is not completely visible, the unvisible parts have garbage
- when using XGetImage(). I tried turning on backing store via
- XChangeWindowAttributes(), but that didn't help much. Is there a way
- to extract the contents of window regardless of its visibility status?
-
- I tried looking at the xwd source, but it basically does what I do, and it
- only extracts what's visible. Any help would be greatly appreciated.
