Function Context.closePath
Adds a line segment to the path from the current point
to
the beginning of the current sub-path, (the most recent
point
passed to moveTo
()), and closes this sub-path.
After this call the current point
will be at the joined
endpoint of the sub-path.
The behavior of closePath
() is distinct from simply
calling lineTo
() with the equivalent coordinate in
the case of stroking. When a closed sub-path is stroked,
there are no caps on the ends of the sub-path. Instead,
there is a line join connecting the final and initial
segments of the sub-path.
If there is no current point
before the call to closePath
(),
this function will have no effect.
Prototype
void closePath();
Note
As of cairo version 1.2.4 any call to closePath
()
will place an explicit MOVE_TO element into the path immediately
after the CLOSE_PATH element, (which can be seen in
copyPath
() for example). This can simplify path processing
in some cases as it may not be necessary to save
the "last
move_to point
" during processing as the MOVE_TO immediately
after the CLOSE_PATH will provide that point
.
