.SH DESCRIPTION
|
|
The
|
|
.ZN XSetClipOrigin
|
|
function sets the clip origin in the specified GC.
|
|
The clip-mask origin is interpreted relative to the origin of whatever
|
|
destination drawable is specified in the graphics request.
|
|
.LP
|
|
.ZN XSetClipOrigin
|
|
can generate
|
|
.ZN BadAlloc
|
|
and
|
|
.ZN BadGC
|
|
errors.
|
|
.LP
|
|
The
|
|
.ZN XSetClipMask
|
|
function sets the clip-mask in the specified GC to the specified pixmap.
|
|
If the clip-mask is set to
|
|
.ZN None ,
|
|
the pixels are are always drawn (regardless of the clip-origin).
|
|
.LP
|
|
.ZN XSetClipMask
|
|
can generate
|
|
.ZN BadAlloc ,
|
|
.ZN BadGC ,
|
|
.ZN BadMatch ,
|
|
and
|
|
.ZN BadValue
|
|
errors.
|
|
.LP
|
|
The
|
|
.ZN XSetClipRectangles
|
|
function changes the clip-mask in the specified GC
|
|
to the specified list of rectangles and sets the clip origin.
|
|
The output is clipped to remain contained within the
|
|
rectangles.
|
|
The clip-origin is interpreted relative to the origin of
|
|
whatever destination drawable is specified in a graphics request.
|
|
The rectangle coordinates are interpreted relative to the clip-origin.
|
|
The rectangles should be nonintersecting, or the graphics results will be
|
|
undefined.
|
|
Note that the list of rectangles can be empty,
|
|
which effectively disables output.
|
|
This is the opposite of passing
|
|
.ZN None
|
|
as the clip-mask in
|
|
.ZN XCreateGC ,
|
|
.ZN XChangeGC ,
|
|
and
|
|
.ZN XSetClipMask .
|
|
.LP
|
|
If known by the client, ordering relations on the rectangles can be
|
|
specified with the ordering argument.
|
|
This may provide faster operation
|
|
by the server.
|
|
If an incorrect ordering is specified, the X server may generate a
|
|
.ZN BadMatch
|
|
error, but it is not required to do so.
|
|
If no error is generated, the graphics
|
|
results are undefined.
|
|
.ZN Unsorted
|
|
means the rectangles are in arbitrary order.
|
|
.ZN YSorted
|
|
means that the rectangles are nondecreasing in their Y origin.
|
|
.ZN YXSorted
|
|
additionally constrains
|
|
.ZN YSorted
|
|
order in that all
|
|
rectangles with an equal Y origin are nondecreasing in their X
|
|
origin.
|
|
.ZN YXBanded
|
|
additionally constrains
|
|
.ZN YXSorted
|
|
by requiring that,
|
|
for every possible Y scanline, all rectangles that include that
|
|
scanline have an identical Y origins and Y extents.
|
|
.LP
|
|
.ZN XSetClipRectangles
|
|
can generate
|
|
.ZN BadAlloc ,
|
|
.ZN BadGC ,
|
|
.ZN BadMatch ,
|
|
and
|
|
.ZN BadValue
|
|
errors.
|
|
.SH DIAGNOSTICS
|
|
.TP 1i
|
|
.ZN BadAlloc
|
|
The server failed to allocate the requested resource or server memory.
|
|
.TP 1i
|
|
.ZN BadGC
|
|
A value for a GContext argument does not name a defined GContext.
|
|
.TP 1i
|
|
.ZN BadMatch
|
|
Some argument or pair of arguments has the correct type and range but fails
|
|
to match in some other way required by the request.
|
|
.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.
