DESCRIPTION

34       These procedures are identical to the Xlib procedures XCreatePixmap and
35       XFreePixmap,  except  that  they  have  extra code to manage X resource
36       identifiers so that identifiers for deleted pixmaps can  be  reused  in
37       the  future.   It  is important for Tk applications to use these proce‐
38       dures rather than XCreatePixmap and XFreePixmap;   otherwise  long-run‐
39       ning applications may run out of resource identifiers.
40
41       Tk_GetPixmap  creates  a  pixmap suitable for drawing in d, with dimen‐
42       sions given by width, height, and depth, and  returns  its  identifier.
43       Tk_FreePixmap  destroys  the  pixmap  given  by  pixmap  and  makes its
44       resource identifier available for reuse.
