           Summary: Getting pixel data
           Product: cairo
           Version: 1.0.2
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: image backend
        AssignedTo: cworth at cworth.org
        ReportedBy: stevech1097 at yahoo.com.au
         QAContact: cairo-bugs at cairographics.org


cairo provides cairo_image_surface_create_for_data() which is useful for reading
pixel data into a cairo surface. There does not seem to be a corresponding
function for getting the pixel data out of an existing cairo surface.

I think a new function
  char* data = cairo_image_surface_get_data()
would be useful to enable reading pixel data into and out of cairo.

PS
I previously mailed the list at
http://lists.freedesktop.org/archives/cairo/2005-September/005364.html
and am opening the bug report so the problem is logged.
