SYNTAX

       XPixmapFormatValues *XListPixmapFormats(display,
       count_return)
             Display *display;
             int *count_return;

       ImageByteOrder(display)

       BitmapBitOrder(display)

       BitmapPad(display)

       BitmapUnit(display)

       DisplayHeight(display, screen_number)

       DisplayHeightMM(display, screen_number)

       DisplayWidth(display, screen_number)

       DisplayWidthMM(display, screen_number)


ARGUMENTS

       display   Specifies the connection to the X server.

       count_return
                 Returns the number of pixmap formats that are
                 supported by the display.

       screen_number
                 Specifies the appropriate screen number on the
                 host server.


DESCRIPTION

       The XListPixmapFormats function returns an array of
       XPixmapFormatValues structures that describe the types of
       Z format images supported by the specified display.  If
       insufficient memory is available, XListPixmapFormats
       returns NULL.  To free the allocated storage for the
       XPixmapFormatValues structures, use XFree.

       The ImageByteOrder macro specifies the required byte order
       for images for each scanline unit in XY format (bitmap) or
       for each pixel value in Z format.

       The BitmapBitOrder macro returns LSBFirst or MSBFirst to
       indicate whether the leftmost bit in the bitmap as dis-

       The DisplayWidth macro returns the width of the screen in
       pixels.

       The DisplayWidthMM macro returns the width of the speci-
       fied screen in millimeters.


STRUCTURES

       The XPixmapFormatValues structure provides an interface to
       the pixmap format information that is returned at the time
       of a connection setup.  It contains:
       typedef struct {
            int depth;
            int bits_per_pixel;
            int scanline_pad;
       } XPixmapFormatValues;
