XCreatePixmap, XFreePixmap - create or destroy pixmaps
SYNTAX
Pixmap XCreatePixmap(display, d, width, height, depth)
Display *display;
Drawable d;
unsigned int width, height;
unsigned int depth;
XFreePixmap(display, pixmap)
Display *display;
Pixmap pixmap;
ARGUMENTS
d Specifies which screen the pixmap is created on.
depth Specifies the depth of the pixmap.
display Specifies the connection to the X server.
pixmap Specifies the pixmap.
width
height Specify the width and height, which define the
dimensions of the pixmap.
DESCRIPTION
The XCreatePixmap function creates a pixmap of the width,
height, and depth you specified and returns a pixmap ID
that identifies it. It is valid to pass an InputOnly win-
dow to the drawable argument. The width and height argu-
ments must be nonzero, or a BadValue error results. The
depth argument must be one of the depths supported by the
screen of the specified drawable, or a BadValue error
results.
The server uses the specified drawable to determine on
which screen to create the pixmap. The pixmap can be used
only on this screen and only with other drawables of the
same depth (see XCopyPlane for an exception to this rule).
The initial contents of the pixmap are undefined.
XCreatePixmap can generate BadAlloc, BadDrawable, and Bad-
Value errors.
The XFreePixmap function first deletes the association
between the pixmap ID and the pixmap. Then, the X server
frees the pixmap storage when there are no references to
it. The pixmap should never be referenced again.
XFreePixmap can generate a BadPixmap error.
full range defined by the argument's type is
accepted. Any argument defined as a set of
alternatives can generate this error.
