Class SVGReader 
java.lang.Objectcom.xerox.VTM.svg.SVGReader
- public class SVGReader
- extends java.lang.Object
An SVG interpreter for VTM - for now it covers a very limited subset of the specification (just enough to interpret GraphViz/Dot SVG output (Ellipse, Text, Path and Rectangle + limited support for Polygon)).

setPositionOffset
public static void setPositionOffset(long dx,
long dy)
- When this is set to something different than 0, all SVG objects will be translated by (dx,dy) in their VTM virtual space. This can be useful if you do not want all objects of the SVG file to all be in the south-east quadrant of the virtual space (SVG files often use positive coordinates only, and their coordinate system is inversed (vertically) w.r.t VTM's coordinate system)
getPositionOffset
public static com.xerox.VTM.engine.LongPoint getPositionOffset()
- get the position offset (0,0 means no offset)
checkSVGPath
public static boolean checkSVGPath(java.lang.String svg)
- check that an SVG path value is supported by the VTM. This does not test for well-formedness of the expression. It just verifies that all SVG commands are actually supported by the VTM (M,m,L,l,H,h,V,v,C,c,Q,q)
