+.SH DESCRIPTION
+The
+.ZN 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, 
+.ZN XReadBitmapFile 
+returns 
+.ZN BitmapOpenFailed .  
+If the file can be opened but does not contain valid bitmap data, 
+it returns 
+.ZN BitmapFileInvalid .  
+If insufficient working storage is allocated,
+it returns
+.ZN BitmapNoMemory .  
+If the file is readable and valid,
+it returns 
+.ZN BitmapSuccess .
+.LP
+.ZN 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 
+.ZN XFreePixmap 
+when finished.
+If \fIname\fP_x_hot and \fIname\fP_y_hot exist,
+.ZN XReadBitmapFile 
+returns them to x_hot_return and y_hot_return;
+otherwise, it returns \-1,\-1.
+.LP
+.ZN XReadBitmapFile
+can generate
+.ZN BadAlloc
+and
+.ZN BadDrawable
+errors.
+.LP
+The
+.ZN XReadBitmapFileData
+function reads in a file containing a bitmap, in the same manner as
+.ZN 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 finished with it by calling
+.ZN XFree .
+The status and other return values are the same as for
+.ZN XReadBitmapFile .
+.LP
+The
+.ZN 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 
+.ZN BitmapOpenFailed .  
+If insufficient memory is allocated,
+.ZN XWriteBitmapFile
+returns
+.ZN BitmapNoMemory ;
+otherwise, on no error,
+it returns
+.ZN BitmapSuccess .
+If x_hot and y_hot are not \-1, \-1, 
+.ZN XWriteBitmapFile
+writes them out as the hotspot coordinates for the bitmap.
+.LP
+.ZN XWriteBitmapFile
+can generate
+.ZN BadDrawable
+and
+.ZN BadMatch
+errors.
+.LP
+The
+.ZN XCreatePixmapFromBitmapData
+function creates a pixmap of the given depth and then does a bitmap-format
+.ZN XPutImage
+of the data into it.
+The depth must be supported by the screen of the specified drawable,
+or a
+.ZN BadMatch
+error results.
+.LP
+.ZN XCreatePixmapFromBitmapData
+can generate
+.ZN BadAlloc
+and
+.ZN BadMatch
+errors.
+.LP
+The
+.ZN XCreateBitmapFromData
+function allows you to include in your C program (using
+.ZN #include )
+a bitmap file that was written out by
+.ZN XWriteBitmapFile
+(X version 11 format only) without reading in the bitmap file.
+The following example creates a gray bitmap:
+.LP
+.Ds 0
+#include "gray.bitmap"
+.sp 6p
+Pixmap bitmap;
+bitmap = XCreateBitmapFromData(display, window, gray_bits, gray_width, gray_height);
+.De
+.LP
+If insufficient working storage was allocated,
+.ZN XCreateBitmapFromData
+returns
+.ZN None .
+It is your responsibility to free the
+bitmap using
+.ZN XFreePixmap
+when finished.
+.LP
+.ZN XCreateBitmapFromData
+can generate a
+.ZN BadAlloc
+error.
+.SH DIAGNOSTICS
+.TP 1i
+.ZN BadAlloc
+The server failed to allocate the requested resource or server memory.
+.TP 1i
+.ZN BadDrawable
+A value for a Drawable argument does not name a defined Window or Pixmap.
+.TP 1i
+.ZN BadMatch
+An
+.ZN InputOnly
+window is used as a Drawable.
