XCB_IMAGE_FORMAT_XY_PIXMAP TODO: NOT YET DOCUMENTED. XCB_IMAGE_FORMAT_Z_PIXMAP TODO: NOT YET DOCUMENTED. TODO: NOT YET DOCUMENTED. drawable TODO: NOT YET DOCUMENTED. x TODO: NOT YET DOCUMENTED. y TODO: NOT YET DOCUMENTED. width TODO: NOT YET DOCUMENTED. height TODO: NOT YET DOCUMENTED. plane_maskTODO: NOT YET DOCUMENTED. REPLY FIELDS response_type The type of this reply, in this case XCB_GET_IMAGE. This field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each other. sequence The sequence number of the last request processed by the X11 server. length The length of the reply, in words (a word is 4 bytes). depth TODO: NOT YET DOCUMENTED. visual TODO: NOT YET DOCUMENTED. DESCRIPTION RETURN VALUE Returns an xcb_get_image_cookie_t. Errors have to be handled when calling the reply function xcb_get_image_reply. If you want to handle errors in the event loop instead, use xcb_get_im- age_unchecked. See xcb-requests(3) for details. ERRORS This request does never generate any errors.
