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_mask TODO: 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 oth- er. 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 func- tion xcb_get_image_reply. If you want to handle errors in the event loop instead, use xcb_get_image_unchecked. See xcb-requests(3) for details. ERRORS This request does never generate any errors.
