allocate and free pixmaps

## 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 XCreatePixmap 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.
