Tk_GetPixmap(3Tk)Tk_GetPixmap(3Tk)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.
KEYWORDS
