NAME
XCreatePixmap, XFreePixmap - create or destroy pixmaps
SYNTAX
Pixmap XCreatePixmap(Display *display, Drawable d,
unsigned int width, unsigned int height, unsigned int
depth);
int XFreePixmap(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
window to the drawable argument.
The width and height arguments 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
BadValue
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.
DIAGNOSTICS
BadAlloc
The server failed to allocate the requested resource or server memory.
BadDrawable
A value for a Drawable argument does not name a defined Window or Pixmap.
BadPixmap
A value for a Pixmap argument does not name a defined Pixmap.
BadValue
Some numeric value falls outside the range of values accepted by the request.
Unless a specific range is specified for an argument, the full range defined
by the argument's type is accepted. Any argument defined as a set of
alternatives can generate this error.
