XCopyArea()XCopyArea()NameXCopyArea – copy an area of a drawable.
Synopsis
XCopyArea(display, src, dest, gc, src_x, src_y, width,
height, dest_x, dest_y)
Display *display;
Drawable src, dest;
GC gc;
int src_x, src_y;
unsigned int width, height;
int dest_x, dest_y;
Arguments
display Specifies a connection to an X server; returned from
XOpenDisplay().
src Specify the source and destination rectangles to be combined.
dest src and dest must have the same root and depth.
gc Specifies the graphics context.
src_x Specify the x and y coordinates of the upper-left corner of
src_y the source rectangle relative to the origin of the source
drawable.
width Specify the dimensions in pixels of both the source and des‐
height tination rectangles.
dest_x Specify the x and y coordinates within the destination win‐
dow.
dest_y
DescriptionXCopyArea() combines the specified rectangle of src with the specified
rectangle of dest. src and dest must have the same root and depth.
If regions of the source rectangle are obscured and have not been
retained in backing_store, or if regions outside the boundaries of the
source drawable are specified, then those regions are not copied.
Instead, the following occurs on all corresponding destination regions
that are either visible or are retained in backing_store. If dest is a
window with a background other than None, the corresponding regions of
the destination are tiled (with plane_mask of all 1's and function
GXcopy) with that background. Regardless of tiling, if the destination
is a window and graphics_exposures in gc is True, then GraphicsExpose
events for all corresponding destination regions are generated. If
graphics_exposures is True but no regions are exposed, then a NoExpose
event is generated.
If regions of the source rectangle are not obscured and graphics_expo‐
sures is False, one NoExpose event is generated on the destination.
XCopyArea() uses these graphics context components: function,
plane_mask, subwindow_mode, graphics_exposures, clip_x_origin,
clip_y_origin, and clip_mask.
Errors
BadDrawable
BadGC
BadMatch The src and dest rectangles do not have the same root and
depth.
