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
pixmap, resource identifier
