CairoContext::closePath

cairo_close_path

(PECL cairo >= 0.1.0)

CairoContext::closePath -- cairo_close_pathCloses the current path

説明

オブジェクト指向型 (method):

public CairoContext::closePath ( void ) : void

手続き型:

cairo_close_path ( CairoContext $context ) : void

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 CairoContext::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 close_path() is distinct from simply calling CairoContext::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 CairoContext::closePath(), this function will have no effect.
