XInitImage(3X)			XLIB FUNCTIONS			XInitImage(3X)

NAME
       XInitImage - initializes the image manipulation routines of an image
       structure

SYNTAX
       Status XInitImage(image)
	     XImage *image;

ARGUMENTS
       ximage	 Specify the image.

DESCRIPTION
       The XInitImage function initializes the internal image manipulation
       routines of an image structure, based on the values of the various
       structure members.  All fields other than the manipulation routines
       must already be initialized.  If the bytes_per_line member is zero,
       XInitImage will assume the image data is contiguous in memory and set
       the bytes_per_line member to an appropriate value based on the other
       members; otherwise, the value of bytes_per_line is not changed.	All of
       the manipulation routines are initialized to functions that other Xlib
       image manipulation functions need to operate on the the type of image
       specified by the rest of the structure.

       This function must be called for any image constructed by the client
       before passing it to any other Xlib function.  Image structures created
       or returned by Xlib do not need to be initialized in this fashion.

       This function returns a nonzero status if initialization of the struc‐
       ture is successful.  It returns zero if it detected some error or
       inconsistency in the structure, in which case the image is not changed.
