NAME

       Graphics::Primitive::Brush - Description of a stroke

DESCRIPTION

       Graphics::Primitive::Brush represents the visible trace of 'ink' along a path.

SYNOPSIS

	 use Graphics::Primitive::Brush;

	 my $stroke = Graphics::Primitive::Brush->new({
	   line_cap => 'round',
	   line_join => 'miter',
	   width => 2
	 });

METHODS

   Constructor
       new Creates a new Graphics::Primitive::Brush.  Defaults to a width of 1, a line_cap 'butt' and a line_join of 'miter'.

   Instance Methods
       color
	   Set/Get this brush's color.

       dash_pattern
	   Set/Get the dash pattern.  A dash pattern is an arrayref of numbers representing the lengths of the various line segments of the dash.
	   Even numbered elements are considered opaque and odd elements are transparent.

       derive
	   Clone this brush but change one or more of it's attributes by passing in a hashref of options:

	     my $new = $brush->derive({ attr => $newvalue });

	   The returned font will be identical to the cloned one, save the attributes specified.

       equal_to ($other)
	   Returns 1 if this brush is equal to the supplied one, else returns 0.

       line_cap
	   Set/Get the line_cap of this stroke.  Valid values are butt, round and square.

       line_join
	   Set/Get the line_join of this stroke. Valid values are miter, round and bevel.

       not_equal_to ($other)
	   Opposite of equal_to.

       width
	   Set/Get the width of this stroke.  Defaults to 1

NAME

       Graphics::Primitive::Canvas - Component composed of paths

DESCRIPTION

       Graphics::Primitive::Canvas is a component for drawing arbitrary things.  It holds Paths and Operations.

SYNOPSIS

	 use Graphics::Primitive::Canvas;

	 my $canvas = Graphics::Primitive::Canvas->new;
	 $canvas->move_to($point); # or just $x, $y
	 $canvas->do($op);

DESCRIPTION

       The Canvas is a container for multiple Paths.  It has a path that is the operative path for all path-related methods.  You can treat the
       Canvas as if it was a path, calling methods like line_to or move_to.

       When you are ready to perform an operation on the path, call the do method with the operation you want to call as an argument.  Drawing a
       line and stroking it would look like:

	 $canvas->move_to(0, 0);
	 $canvas->line_to(10, 10);
	 my $op = Graphics::Primitive::Operation::Stroke->new;
	 $stroke->brush->color(
	     Graphics::Color::RGB->new(red => 0, blue => 1, green => 1)
	 );
	 $canvas->do($op);

       When you instantiate a Canvas a newly instantiated path resides in path.  After you call do that current path is moved to the paths list
       and new path is placed in current_path.	If you want to keep the path around you can call save before do then call restore to put a saved
       copy of the path back into path.

METHODS

   Constructor
       new Creates a new Graphics::Primitive::Canvas

   Instance Methods
       do  Given an operation, pushes the current path onto the path stack.

	     FIXME: Example

       path
	   The current path this canvas is using.

       path_count
	   Count of paths in paths.

       paths
	   Arrayref of hashrefs representing paths combined with their operations:

	     [
	       {
		   path => $path,
		   op	=> $op
	       },
	     ]

       restore
	   Replace the current path by popping the top path from the saved path list.

       save
	   Copy the current path and push it onto the stack of saved paths.

       saved_paths
	   List of saved paths.  Add to the list with save and pop from it using restore.

       saved_path_count
	   Count of paths saved in saved_paths.
