Sprite

ImportSVG

SVG XML import parser creating a list of svg shape objects. AS3 rewrite of drawsvg_mm.as which was based on drawsvg.as.

Summary

ImportSVG	SVG XML import parser creating a list of svg shape objects.
Public properties
shapes	Array of ShapeSVG objects.
Public methods
parseSVG	Parses an SVG XML text into the shapes array.
generateCode	Generates and returns an AS3 method that returns a Sprite representing the imported SVG path definitions.
numPoints	Returns the number of line segment points in all defined shapes.
Private methods
findPathNode	Recursively looks at XML objects to find PATH nodes.
parseFill	Parses a SVG fill attribute.
parseStroke	Parses a SVG stroke line style.
defineShape	Reads a SVG path node.
createShapeDef	Creates and returns a ShapeSVG object from the d attribute of the SVG PATH tag given in the cmds array.

Public properties

shapes

public var shapes: Array

Array of ShapeSVG objects.

Public methods

parseSVG

public function parseSVG( srcXML: String,
parseTolerance: int ):int

Parses an SVG XML text into the shapes array.

Parameters

srcXML	SVG XML document
parseTolerance	Approximation tolerance, see Bezier

Returns

Number of shapes found

generateCode

public function generateCode():String

Generates and returns an AS3 method that returns a Sprite representing the imported SVG path definitions.

numPoints

public function get numPoints():int

Returns the number of line segment points in all defined shapes.

Private methods

findPathNode

private function findPathNode( node: XMLNode,
defaultFill: Object,
defaultStroke: Object ):void

Recursively looks at XML objects to find PATH nodes. When one is found, it calls defineShape to parse the PATH node and calls createShapeDef to create a ShapeSVG object which is pushed onto the shapes array.

parseFill

private function parseFill( attributes: Object,
defaultFill: Object ):Object

Parses a SVG fill attribute.

parseStroke

private function parseStroke( attributes: Object,
defaultStroke: Object ):Object

Parses a SVG stroke line style.

defineShape

private function defineShape( node: XMLNode,
defaultFill: Object,
defaultStroke: Object ):void

Reads a SVG path node.

Extracts

the rotation to be applied
an array of each letter command and coordinate in the d attribute
fill and stroke colors

Then calls createShapeDef to create a ShapeSVG object

createShapeDef

private function createShapeDef( cmds: Array,
rotation: int,
fill: Object,
stroke: Object ):ShapeSVG

Creates and returns a ShapeSVG object from the d attribute of the SVG PATH tag given in the cmds array.
