Class GenerateSVG

java.lang.Object
  org.geotools.svg.GenerateSVG

public class GenerateSVG

extends java.lang.Object

This is a simple support class which allows you to generate an SVG file from a map. To use, setup a Map object with the layers you want to render, create an envelope for the region to be drawn and pass in an OutputStream (probably attached to a new file) for the resulting SVG information to be stored in. Optionaly you can change the default size of the SVG cavas (in effect increasing the resolution) by calling setCavasSize before calling go.
