Tk_FreePixmap(display, pixmap)
ARGUMENTS
Display *display (in) X display for the pixmap.
Drawable d (in) Pixmap or window where the new pixmap

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