I don't know anything about Win32DIB, but handles should always be atoms. I think this is just a documentation error as the sequence element [DibHandle] will be an atom.

Is the following relevant? It's not involving TWO windows, just one window with only part repainted:

[proc]
repaintRect ( window, x1, y1, x2, y2 )
Force window to be partially repainted.
Category: Graphics

This sends repaints at the specified portion of the window with the background color, erasing that portion of it. It then triggers an Paint event for that window, passing the erased area as parameters.

Example:

repaint only a portion of MyWindow
repaintRect( myWindow, 1, 1, 10, 10 )

If that doesn't do what you want, then a child window, positoned and sized as you wish, with style { WS_CHILD } should work, I think.

functions like colorizeDib() drawDib() and saveDib() use the sequence mydib not just the handle in the first position. I guess it could be called a reference instance of a bitmap, not the bitmap.

This is what I used in Photuki2

 scrndib          =newDib(cc*8+1,cc*8+1) 
 
-- create a off screen control to hold completed image 
 pixmap = subClassControl({Pixmap, 0}, scrndib[DibHandle]) 
 
-- fill the pixmap with background color  
         setBackColor (pixmap, template_bgcolor )

Here's the code I finally used in my CrossHairs. It's in the Archives

                      dib[DibWidth], 
                      dib[DibHeight])
