geometryToSvgPath

public static java.lang.String geometryToSvgPath(Geometry geom,
                                                 Envelope env,
                                                 double scaleFactor,
                                                 double minX,

Converts a Geometry into a SVG path sequence.

Parameters:

geom - the Geometry to convert.

env - the Envelope we use for the coordinate conversion.

minX, - maxX, minY, maxY the maximum coordinates for the SVG coordinates and corresponding to the Envelope env.

Returns:

a string for use in a SVG path element.
