CairoContext::copyPathFlat

cairo_copy_path_flat

(PECL cairo >= 0.1.0)

CairoContext::copyPathFlat -- cairo_copy_path_flat — Gets a flattened copy of the current path

説明

Object oriented style (method):

public CairoPath CairoContext::copyPathFlat ( void )

Procedural style:

CairoPath cairo_copy_path_flat ( CairoContext $context )

Gets a flattened copy of the current path and returns it to the user as a CairoPath.

This function is like CairoContext::copyPath() except that any curves in the path will be approximated with piecewise-linear approximations, (accurate to within the current tolerance value). That is, the result is guaranteed to not have any elements of type CAIRO_PATH_CURVE_TO which will instead be replaced by a series of CAIRO_PATH_LINE_TO elements.

パラメータ

context

A CairoContext object

返り値

A copy of the current path
