____________________________________________________________________________________________________________
NAME
Tk_GetPixmap, Tk_FreePixmap - allocate and free pixmaps
SYNOPSIS
#include <tk.h>
Pixmap
Tk_GetPixmap(display, d, width, height, depth)
Tk_FreePixmap(display, pixmap)
ARGUMENTS
Display *display (in) X display for the pixmap.
Drawable d (in) Pixmap or window where the new pixmap will be used for drawing.
int width (in) Width of pixmap.
int height (in) Height of pixmap.
int depth (in) Number of bits per pixel in pixmap.
Pixmap pixmap (in) Pixmap to destroy.

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 procedures rather than XCre-atePixmap XCreatePixmap
atePixmap and XFreePixmap; otherwise long-running applications may run out of resource identifiers.
Tk_GetPixmap creates a pixmap suitable for drawing in d, with dimensions given by width, height, and
depth, and returns its identifier. Tk_FreePixmap destroys the pixmap given by pixmap and makes its
resource identifier available for reuse.
