+ NAME
+ XCreateInsensitivePixmap - create a grayed-out copy of a pixmap
+
+ SYNOPSIS
+ Pixmap XCreateInsensitivePixmap( Display *display, Pixmap pixmap )
+
+ DESCRIPTION
+ This function creates a grayed-out copy of the argument pixmap, suitable
+ for use as a XmLabel's XmNlabelInsensitivePixmap resource.
+
+ RETURN VALUES
+ The return value is the new Pixmap id or zero on error. Errors include
+ a NULL display argument or an invalid Pixmap argument.
+
+ ERRORS
+ If one of the XLib functions fail, it will produce a X error. The
+ default X error handler prints a diagnostic and calls exit().
+
+ SEE ALSO
+ XCopyArea(3), XCreateBitmapFromData(3), XCreateGC(3), XCreatePixmap(3),
+ XFillRectangle(3), exit(2)
