Tk_GetPixmap, Tk_FreePixmap — allocate and free pixmaps
#include <tk.h>
Pixmap
Tk_GetPixmap(display, d, width, height, depth)
Tk_FreePixmap(display, pixmap)
- 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.
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.
