how i can convert a path into Its composer points by using batik ?

Hi
Thank you for reading my post.
how i can convert a path (SVG path element) into its corresponding points ?
I mean points that i can use to draw the path on a raster canvas.

Thanks

If you already have java Shape object it will be simpler, just use
PathIterator

PathIterator pi = shape.getPathIterator(null)
float[] coords = new float[6];
        while (!pi.isDone()) {
            int segment = pi.currentSegment(coords);
            if (segment == PathIterator.SEG_MOVETO) {
                
            } else if (segment == PathIterator.SEG_CLOSE) {
                
            } else if (segment == PathIterator.SEG_LINETO) {
                
            } else if (segment == PathIterator.SEG_QUADTO) {
                
            } else if (segment == PathIterator.SEG_CUBICTO) {
                
            }
            pi.next();
        }

Please note, the above code is straight typing, probably have syntax
error, etc. Please check the Java API PathIterator doc for correct
syntax and other option like flatten

Hi
Can you please explain more ,
I have an java.awt.shape object   , now i want to have a sequence of 
straight lines that create that shape , can you give me more details on 
, how i can achieve this ?
I should say that , indeed i have SVGDocument and i build the above 
shape by using the document node.
so if it is require i have the SVGdocument too.

I tried both

AWTPathProducer , PathParser

but i did not find a method that get a shape and return a sequence of lines.

Thanks

   Well Batik will draw the path on a raster canvas for you... It's sort
of it's purpose in life ;)

   Anyway if you have the 'd' data you can use the 
batik.parser.AWTPathProducer with the batik.parser.PathParser
to create an AWT GeneralPath which you can either query for
the real 'curve' segments (quadradic and cubic beziers, lines, etc)
or you can call flatten on that path and get a sequence of straight
lines that approximate the original path...
