-.SH DESCRIPTION
-The
-.ZN 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,
-.ZN 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
-type of image specified by the rest of the structure.
-.LP
-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.
-.LP
-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.
-.LP
-The
-.ZN XCreateImage
-function allocates the memory needed for an
-.ZN XImage
-structure for the
-specified display but does not allocate space for the image itself.
-Rather, it initializes the structure byte-order, bit-order, and bitmap-unit
-values from the display and returns a pointer to the
-.ZN XImage
-structure.
-The red, green, and blue mask values are defined for Z format images only
-and are derived from the
-.ZN Visual
-structure passed in.
-Other values also are passed in.
-The offset permits the rapid displaying of the image without requiring each
-scanline to be shifted into position.
-If you pass a zero value in bytes_per_line,
-Xlib assumes that the scanlines are contiguous
-in memory and calculates the value of bytes_per_line itself.
-.LP
-Note that when the image is created using
-.ZN XCreateImage ,
-.ZN XGetImage ,
-or
-.ZN XSubImage ,
-the destroy procedure that the
-.ZN XDestroyImage
-function calls frees both the image structure
-and the data pointed to by the image structure.
-.LP
-The basic functions used to get a pixel, set a pixel, create a subimage,
-and add a constant value to an image are defined in the image object.
-The functions in this section are really macro invocations of the functions
-in the image object and are defined in
-.hN X11/Xutil.h .
-.LP
-The
-.ZN 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.
-.LP
-The
-.ZN XPutPixel
-function overwrites the pixel in the named image with the specified pixel value.
-The input pixel value must be 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.
-.LP
-The
-.ZN XSubImage
-function creates a new image that is a subsection of an existing one.
-It allocates the memory necessary for the new
-.ZN 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.
-.LP
-The
-.ZN XAddPixel
-function adds a constant value to every pixel in an image.
-It is useful when you have a base pixel value from allocating
-color resources and need to manipulate the image to that form.
-.LP
-The
-.ZN XDestroyImage
-function deallocates the memory associated with the
-.ZN XImage
-structure.
