           Summary: GetPixel() returns wrong value for monochrome bitmaps
           Product: Wine
           Version: CVS
          Platform: Other
        OS/Version: other
            Status: NEW
          Keywords: download, source
          Severity: normal
          Priority: P2
         Component: wine-x11driver
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: hallo(a)michael-kaufmann.ch


The GDI function GetPixel() should return 0x00ffffff for white pixels in a  
monochrome bitmap. Wine returns 0x00010000 on my system.  
  
GetPixel() is implemented in dlls/x11drv/graphics.c. The function calls  
XGetPixel() and then passes the pixel value to  
X11DRV_PALETTE_ToLogical in dlls/x11drv/palette.c.  
Probably the bug is in this function.  
 
I've created an example program and hope that somebody will try to fix this 
bug.
