xcb_shm_put_image(3) XCB Requests xcb_shm_put_image(3)

NAME

xcb_shm_put_image - Copy data from the shared memory to the specified drawable.

SYNOPSIS

#include <xcb/shm.h>

Request function

xcb_void_cookie_t xcb_shm_put_image(xcb_connection_t *conn, xcb_drawable_t drawable, xcb_gcontext_t gc, uint16_t total_width, uint16_t total_height, uint16_t src_x, uint16_t src_y, uint16_t src_width, uint16_t src_height, int16_t dst_x, int16_t dst_y, uint8_t depth, uint8_t format, uint8_t send_event, xcb_shm_seg_t shmseg, uint32_t offset);

REQUEST ARGUMENTS

The XCB connection to X11.
The drawable to draw to.
The graphics context to use.
The total width of the source image.
The total height of the source image.
The source X coordinate of the sub-image to copy.
The source Y coordinate of the sub-image to copy.
The width, in source image coordinates, of the data to copy from the source. The X server will use this to determine the amount of data to copy. The amount of the destination image that is overwritten is determined automatically.
The height, in source image coordinates, of the data to copy from the source. The X server will use this to determine the amount of data to copy. The amount of the destination image that is overwritten is determined automatically.
The X coordinate on the destination drawable to copy to.
The Y coordinate on the destination drawable to copy to.
The depth to use.
The format of the image being drawn. If it is XYBitmap, depth must be 1, or a "BadMatch" error results. The foreground pixel in the GC determines the source for the one bits in the image, and the background pixel determines the source for the zero bits. For XYPixmap and ZPixmap, the depth must match the depth of the drawable, or a "BadMatch" error results.
True if the server should send an XCB_SHM_COMPLETION event when the blit completes.
TODO: NOT YET DOCUMENTED.
The offset that the source image starts at.

DESCRIPTION

Copy data from the shared memory to the specified drawable. The amount of bytes written to the destination image is always equal to the number of bytes read from the shared memory segment.

RETURN VALUE

Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the event loop.

If you want to handle errors directly with xcb_request_check instead, use xcb_shm_put_image_checked. See xcb-requests(3) for details.

ERRORS

This request does never generate any errors.
