Get & Set pixel from a pixmap.

["Eleni Ryan" <eleni ryan caris com>]

Hi,

I want to get & then set a pixel value from a GdkPixmap, but can't seem to
find where to start.  I see that pixels can be manipulated in a GdkImage
using gdk_image_get_pixel() & gdk_image_put_pixel(), however I need to
manipulate an off-screen pixmap rather than a copy of the window.

Does anybody have any idea how to do this or an example?

Thanks,
Eleni
