* @short_description: Grab pixel data from the screen
|
||
|
|
*
|
||
|
|
* The #ShellScreenGrabber object is used to download previous drawn
|
||
|
|
* content to the screen. It internally uses pixel-buffer objects if
|
||
|
|
* available, otherwise falls back to cogl_read_pixels().
|
||
|
|
*
|
||
|
|
* If you are repeatedly grabbing images of the same size from the
|
||
|
|
* screen, it makes sense to create one #ShellScreenGrabber and keep
|
||
|
|
* it around. Otherwise, it's fine to simply create one as needed and
|
||
|
|
* then get rid of it.
