XGetSubImage() XGetSubImage()
Name
XGetSubImage - copy a rectangle in drawable to a location within the pre-existing image.
Synopsis
XImage *XGetSubImage(display, drawable, x, y, width, height,
plane_mask, format, dest_image, dest_x, dest_y)
Display *display;
Drawable drawable;
int x, y;
unsigned int width, height;
unsigned long plane_mask;
int format;
XImage *dest_image;
int dest_x, dest_y;
Arguments
display Specifies a connection to an X server; returned from XOpenDisplay().
drawable Specifies the drawable from which the rectangle is to be copied.
x Specify the x and y coordinates of the upper-left corner of the rectangle, relative to the origin of the drawable.
y
width Specify the width and height in pixels of the subimage taken.
height
plane_mask
Specifies which planes of the drawable are transferred to the image.
format Specifies the format for the image. Either XYPixmap or ZPixmap.
dest_image
Specifies the destination image.
dest_x Specify the x and y coordinates of the destination rectangle's upper-left corner, relative to the image's origin.
dest_y
Returns
The same image specified by dest_image.
Description
XGetSubImage() updates the dest_image with the specified subimage in the same manner as XGetImage(), except that it does not create the
image or necessarily fill the entire image. If format is XYPixmap, the function transmits only the bit planes you specify in plane_mask.
If format is ZPixmap, the function transmits as zero the bits in all planes not specified in plane_mask. The function performs no range
checking on the values in plane_mask and ignores extraneous bits.
The depth of the destination XImage structure must be the same as that of the drawable. Otherwise, a BadMatch error is generated. If the
specified subimage does not fit at the specified location on the destination image, the right and bottom edges are clipped. If the draw-
able is a window, the window must be mapped or held in backing store, and it must be the case that, if there were no inferiors or overlap-
ping windows, the specified rectangle of the window would be fully visible on the screen. Otherwise, a BadMatch error is generated.
If the window has a backing store, the backing store contents are returned for regions of the window that are obscured by noninferior win-
dows. Otherwise, the return contents of such obscured regions are undefined. Also undefined are the returned contents of visible regions
of inferiors of different depth than the specified window.
XSubImage() extracts a subimage from an image, instead of from a drawable like XGetSubImage().
If a problem occurs, XGetSubImage() returns NULL.
For more information on images, see Volume One, Chapter 6, Drawing Graphics and Text.
