Class SVGImageManager

java.lang.Object

org.eclnt.util.image.SVGImageManager

public class SVGImageManager
extends Object

Utility for flexibly adapting flat SVG icon images and update their fill color and their size.

Purpose: have one icon imagea definition and derive all variations of the icon by this utility instead of copying/pasting the SVG multiple times.

The utitily already covers quite typical definitions of flat SVG icon images but of course can not cover all - because there is some individual variation how SVG is structured. You may add own conversion algorithms by calling addSVGImageUpdate(ISVGImageUpdate).

The utility can be called by URL as well (".ccsvg" access, DynamicImageServlet.
