Tk_GetPixmap, Tk_FreePixmap — allocate and free pixmaps
Tk_GetPixmap(display, d, width, height, depth)
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.
- 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.
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.
