|
|
.SH DESCRIPTION
|
|
The
|
|
.ZN 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
|
|
.ZN InputOnly
|
|
window to the drawable argument.
|
|
The width and height arguments must be nonzero,
|
|
or a
|
|
.ZN BadValue
|
|
error results.
|
|
The depth argument must be one of the depths supported by the screen
|
|
of the specified drawable,
|
|
or a
|
|
.ZN BadValue
|
|
error results.
|
|
.LP
|
|
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
|
|
.ZN XCopyPlane
|
|
for an exception to this rule).
|
|
The initial contents of the pixmap are undefined.
|
|
.LP
|
|
.ZN XCreatePixmap
|
|
can generate
|
|
.ZN BadAlloc ,
|
|
.ZN BadDrawable ,
|
|
and
|
|
.ZN BadValue
|
|
errors.
|
|
.LP
|
|
The
|
|
.ZN 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.
|
|
.LP
|
|
.ZN XFreePixmap
|
|
can generate a
|
|
.ZN BadPixmap
|
|
error.
|
|
.SH DIAGNOSTICS
|
|
.TP 1i
|
|
.ZN BadAlloc
|
|
The server failed to allocate the requested resource or server memory.
|
|
.TP 1i
|
|
.ZN BadDrawable
|
|
A value for a Drawable argument does not name a defined Window or Pixmap.
|
|
.TP 1i
|
|
.ZN BadPixmap
|
|
A value for a Pixmap argument does not name a defined Pixmap.
|
|
.TP 1i
|
|
.ZN 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.
