ImageByteOrder(3)		XLIB FUNCTIONS		     ImageByteOrder(3)

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 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, XListPixmap‐
       Formats returns NULL.  To free the allocated storage for the XPixmap‐
       FormatValues 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 specified 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;
