XGetPixel(3X)							  XLIB FUNCTIONS						     XGetPixel(3X)

NAME

       XGetPixel - returns the specified pixel from the named image

SYNTAX

       unsigned long XGetPixel(ximage, x, y)
	     XImage *ximage;
	     int x;
	     int y;

ARGUMENTS

       ximage	 Specifies the image.

       x
       y	 Specify the x and y coordinates.

DESCRIPTION

       The XGetPixel function returns the specified pixel from the named image.  The pixel value is returned in normalized format (that is, the
       least-significant byte of the long is the least-significant byte of the pixel).	The image must contain the x and y coordinates.

XSubImage(3X)							  XLIB FUNCTIONS						     XSubImage(3X)

NAME

       XSubImage - image utilities

SYNTAX

       XImage *XSubImage(ximage, x, y, subimage_width, subimage_height)
	     XImage *ximage;
	     int x;
	     int y;
	     unsigned int subimage_width;
	     unsigned int subimage_height;

ARGUMENTS

       ximage	 Specifies the image.

       x
       y	 Specify the x and y coordinates.

       subimage_width
		 Specifies the width of the new subimage, in pixels.

       subimage_height
		 Specifies the height of the new subimage, in pixels.

DESCRIPTION

       The XSubImage function creates a new image that is a subsection of an existing one.  It allocates the memory necessary for the new XImage
       structure and returns a pointer to the new image.  The data is copied from the source image, and the image must contain the rectangle
       defined by x, y, subimage_width, and subimage_height.
