ImageByteOrder(3X11)     XLIB FUNCTIONS      ImageByteOrder(3X11)

NAME

     ImageByteOrder, BitmapBitOrder, BitmapPad, BitmapUnit,
     DisplayHeight, DisplayHeightMM, DisplayWidth,
     DisplayWidthMM, XListPixmapFormats, XPixmapFormatValues -
     image format functions and macros

SYNTAX

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

     int ImageByteOrder(Display *display);

     int BitmapBitOrder(Display *display);

     int BitmapPad(Display *display);

     int BitmapUnit(Display *display);

     int DisplayHeight(Display *display, int screen_number);

     int DisplayHeightMM(Display *display, int screen_number);

     int DisplayWidth(Display *display, int screen_number);

     int DisplayWidthMM(Display *display, int screen_number);

ARGUMENTS

     display   Specifies the connection to the X server.

     count_return
               Returns the number of pixmap formats that are sup-
               ported by the display.

     screen_number
               Specifies the appropriate screen number on the
               host server.

DESCRIPTION

     The XListPixmapFormats function returns an array of XPixmap-
     FormatValues 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 displayed
     on the screen is the least or most significant bit in the

     unit.

     The BitmapPad macro returns the number of bits that each
     scanline must be padded.

     The BitmapUnit macro returns the size of a bitmap's scanline
     unit in bits.

     The DisplayHeight macro returns the height of the specified
     screen in pixels.

     The DisplayHeightMM macro returns the height of the speci-
     fied screen in millimeters.

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

     The DisplayWidthMM macro returns the width of the specified
     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;
