cairoClosePath: cairoClosePath

Description Usage Arguments Details Author(s)

View source: R/cairoFuncs.R


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 cairoMoveTo), and closes this sub-path. After this call the current point will be at the joined endpoint of the sub-path.





[Cairo] a cairo context


The behavior of cairoClosePath is distinct from simply calling cairoLineTo 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 cairoClosePath, this function will have no effect.

Note: As of cairo version 1.2.4 any call to cairoClosePath will place an explicit MOVE_TO element into the path immediately after the CLOSE_PATH element, (which can be seen in cairoCopyPath 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.
