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

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

virtual void gnash::PathParser::curveTo

(

const Edge &

curve

)

[pure virtual]

Draw the given curve using the path pencil.

virtual void gnash::PathParser::fillShape

(

)

[inline, virtual]

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.

virtual void gnash::PathParser::lineTo

(

const point &

p

)

[pure virtual]

Draw a straight line to the given point.

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.

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.

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.

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.
