my Gnome::Cairo $context;
my Gnome::Cairo::ImageSurface $surface;
my Gnome::Cairo::Path $path;

Methods

new

length

Return the length of the data array in the cairo_path_t structure.

method length ( --> UInt )

walk-path

A convenience method to walk over the set of parts in a path. The method will go through the elements of he path and calls user methods in an object given by the user to let the user process specific parts in the path.

method walk-path (
  Any:D $user-object, Str:D $move-to, Str:D $line-to,
  Str:D $curve-to, Str:D $close-path
}

$move-to, $line-to, $curve-to and $close-path are the names of the methods defined in $user-object.

status

Return status from the path structure cairo_path_t.

method status ( --> cairo_status_t )
