Tk Library Procedures
Tk_GetPixmap, Tk_FreePixmap - allocate and free pixmaps
Tk_GetPixmap(display, d, width, height, depth)
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.
pixmap, resource identifier
