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

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

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

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

The macro returns the height of the specified screen in millimeters.

The macro returns the width of the screen in pixels.

The macro returns the width of the specified screen in millimeters.

STRUCTURES
The 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;
