Detailed Description

PathParser is a class which aims to efficiently transpose Flash paths into well formed, single-filled shapes. A renderer should utilize this class by subclassing PathParser. The methods reimplemented will receive low level path information (e.g., moveTo).

Constructor & Destructor Documentation

PathParser()

gnash::PathParser::PathParser	(	const std::vector< Path > &	paths,
		size_t	num_styles
	)

Parameters

paths	list of Flash paths to be 'parsed'.
num_styles	count of fill styles pointed to by the first argument.

Member Function Documentation

curveTo()

virtual void gnash::PathParser::curveTo ( const Edge &  curve )

pure virtual

Draw the given curve using the path pencil.

Referenced by run().

fillShape()

virtual void gnash::PathParser::fillShape ( )

inlinevirtual

Fill a single shape. Implementation is optional, because most renderers can handle multiple well-formed, singly-filled shapes and can do the render/fill stage during terminateFill(). However, those that can't may implement this method.

References gnash::key::p.

Referenced by run().

lineTo()

virtual void gnash::PathParser::lineTo ( const point &  p )

pure virtual

Draw a straight line to the given point.

Referenced by run().

moveTo()

virtual void gnash::PathParser::moveTo ( const point &  p )

pure virtual

Move the path pencil to the given location. Thus a new shape should be started. The parser may invoke this method several times for a single fill style, creating several shapes.

Referenced by run().

prepareFill()

virtual void gnash::PathParser::prepareFill ( int  fill_style, const SWFCxForm &  cx  )

pure virtual

Prepare the fill style for subsequent use for filling one or more shapes.

Parameters

fill_style

fill style number, as indicated by class Path.

Referenced by run().

run()

void gnash::PathParser::run	(	const SWFCxForm &	cx,
		const SWFMatrix &	mat
	)

Runs the path parser, invoking the pure virtual methods where appropriate.

Parameters

cx	the color transform that will be passed to prepareFill.
mat	the SWFMatrix that will be passed to prepareFill.

terminateFill()

virtual void gnash::PathParser::terminateFill ( int  fill_style )

pure virtual

Terminates the fill style, that is, precludes the fill style from further use, which may be freed or otherwise cleaned up. Most renderers should fill the paths previously parsed.
