Interface SVGTarget

All Superinterfaces:

RenderTarget

All Known Implementing Classes:

SVGRenderTargetBuilder.SVGRenderTargetImpl

public interface SVGTarget
extends RenderTarget

Rendering target to SVG format.

This target is used by renderers objects to render a graph to a SVG DOM and uses the Batik library to transcode the SVG DOM in a SVG document.

To allow further document further manipulation the DOM is organized with top elements. Top elements are nodes, edges, node-labels, edge-labels and arrows and are elements to append items to. For instance when a node label element is created it should be appended to the node-label element instead of directly to the root. Use the getTopElement() method to retrieve or create top elements.

Method Detail

createElement

org.w3c.dom.Element createElement(java.lang.String qualifiedName)

Create a new element qualifiedName in the document.

Parameters:

qualifiedName - the name of the element

Returns:

the newly created element

createTextNode

org.w3c.dom.Text createTextNode(java.lang.String data)

Create a new text node with data in it.

Parameters:

data - the text data

Returns:

the newly created text node

getTopElement

org.w3c.dom.Element getTopElement(java.lang.String name)

Returns the top element name in the document. Top elements are direct children of the root node and help to organize the SVG document (e.g. all edges in the same parent DOM node). Create the top element if it missing.

Parameters:

name - the top element name to lookup

Returns:

the top element

getDocument

org.w3c.dom.Document getDocument()

Returns the SVG document

Returns:

the SVG document

getScaleRatio

float getScaleRatio()

When SCALE_STROKES property is true returns the scale ratio to scale strokes with.

Returns:

the current scale ratio

toHexString

java.lang.String toHexString(java.awt.Color color)

Returns color in the hex format (e.g. #ff0000).

Parameters:

color - the color to convert

Returns:

the color in a hex format
