xinitimage

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 cre-
       ated or returned by Xlib do not need to be initialized in this fashion.

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