XReadBitmapFile(3)		XLIB FUNCTIONS		    XReadBitmapFile(3)

       XReadBitmapFile, XReadBitmapFileData, XWriteBitmapFile, XCre‐
       atePixmapFromBitmapData, XCreateBitmapFromData - manipulate bitmaps

       int XReadBitmapFile(Display *display, Drawable d, char *filename,
	      unsigned int *width_return, unsigned int *height_return, Pixmap
	      *bitmap_return, int *x_hot_return, int *y_hot_return);

       int XReadBitmapFileData(char *filename, unsigned int *width_return,
	      unsigned int *height_return, unsigned char *data_return, int
	      *x_hot_return, int *y_hot_return);

       int XWriteBitmapFile(Display *display, char *filename, Pixmap bitmap,
	      unsigned int width, unsigned int height, int x_hot, int y_hot);

       Pixmap XCreatePixmapFromBitmapData(Display *display, Drawable d, char
	      *data, unsigned int width, unsigned int height, unsigned long
	      fg, unsigned long bg, unsigned int depth);

       Pixmap XCreateBitmapFromData(Display *display, Drawable d, char *data,
	      unsigned int width, unsigned int height);

       bitmap	 Specifies the bitmap.

		 Returns the bitmap that is created.

       d	 Specifies the drawable that indicates the screen.

       data	 Specifies the data in bitmap format.

       data	 Specifies the location of the bitmap data.

		 Returns the bitmap data.

       depth	 Specifies the depth of the pixmap.

       display	 Specifies the connection to the X server.

       bg	 Specify the foreground and background pixel values to use.

       filename	 Specifies the file name to use.  The format of the file name
		 is operating-system dependent.

       height	 Specify the width and height.

		 Return the width and height values of the read in bitmap

       y_hot	 Specify where to place the hotspot coordinates (or -1,-1 if
		 none are present) in the file.

		 Return the hotspot coordinates.

       The XReadBitmapFile function reads in a file containing a bitmap.  The
       file is parsed in the encoding of the current locale.  The ability to
       read other than the standard format is implementation-dependent.	 If
       the file cannot be opened, XReadBitmapFile returns BitmapOpenFailed.
       If the file can be opened but does not contain valid bitmap data, it
       returns BitmapFileInvalid.  If insufficient working storage is allo‐
       cated, it returns BitmapNoMemory.  If the file is readable and valid,
       it returns BitmapSuccess.

       XReadBitmapFile returns the bitmap's height and width, as read from the
       file, to width_return and height_return.	 It then creates a pixmap of
       the appropriate size, reads the bitmap data from the file into the
       pixmap, and assigns the pixmap to the caller's variable bitmap.	The
       caller must free the bitmap using XFreePixmap when finished.  If
       name_x_hot and name_y_hot exist, XReadBitmapFile returns them to
       x_hot_return and y_hot_return; otherwise, it returns -1,-1.

       XReadBitmapFile can generate BadAlloc and BadDrawable errors.

       The XReadBitmapFileData function reads in a file containing a bitmap,
       in the same manner as XReadBitmapFile, but returns the data directly
       rather than creating a pixmap in the server.  The bitmap data is
       returned in data_return; the client must free this storage when fin‐
       ished with it by calling XFree.	The status and other return values are
       the same as for XReadBitmapFile.

       The XWriteBitmapFile function writes a bitmap out to a file in the X
       Version 11 format.  The name used in the output file is derived from
       the file name by deleting the directory prefix.	The file is written in
       the encoding of the current locale.  If the file cannot be opened for
       writing, it returns BitmapOpenFailed.  If insufficient memory is allo‐
       cated, XWriteBitmapFile returns BitmapNoMemory; otherwise, on no error,
       it returns BitmapSuccess.  If x_hot and y_hot are not -1, -1,
       XWriteBitmapFile writes them out as the hotspot coordinates for the

       XWriteBitmapFile can generate BadDrawable and BadMatch errors.

       The XCreatePixmapFromBitmapData function creates a pixmap of the given
       depth and then does a bitmap-format XPutImage of the data into it.  The
       depth must be supported by the screen of the specified drawable, or a
       BadMatch error results.

       XCreatePixmapFromBitmapData can generate BadAlloc and BadMatch errors.

       The XCreateBitmapFromData function allows you to include in your C pro‐
       gram (using #include) a bitmap file that was written out by
       XWriteBitmapFile (X version 11 format only) without reading in the bit‐
       map file.  The following example creates a gray bitmap:

       #include "gray.bitmap"
       Pixmap bitmap;
       bitmap = XCreateBitmapFromData(display, window, gray_bits, gray_width, gray_height);

       If insufficient working storage was allocated, XCreateBitmapFromData
       returns None.  It is your responsibility to free the bitmap using
       XFreePixmap when finished.

       XCreateBitmapFromData can generate a BadAlloc error.

       BadAlloc	 The server failed to allocate the requested resource or
		 server memory.

		 A value for a Drawable argument does not name a defined Win‐
		 dow or Pixmap.

       BadMatch	 An InputOnly window is used as a Drawable.
