cairoCopyPathFlat: cairoCopyPathFlat
Description
Gets a flattened copy of the current path and returns it to the
user as a CairoPath. See CairoPathData for hints on
how to iterate over the returned data structure.Usage
cairoCopyPathFlat(cr)
Details
This function is like cairoCopyPath 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.
This function will always return a valid pointer, but the result
will have no data (data== NULL and
num_data==0), if either of the following
conditions hold:
