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.
