Hi,
I hope you can help me out with some problems I've run into using Batik.
I've been Googling for this the last few days without coming up with a
solution. I've also tried asking on some newsgroups but to no success.
I've recently found the batik and the VectorGraphics package from the
freehep libraries
<url:http://java.freehep.org/vectorgraphics/index.html> which mostly do
exactly what I need; to load an SVG document and convert it to another
vector graphics format (.cgm or .pdf).
My problem is that freehep only use a standard Graphics2D-enabled
component (i.e. JComponent) to be able to export. Batik, however, only
outputs images to it's custom JSVGCanvas, which is not directly
compatible with freehep.
Using only a JComponent which I draw to myself using the paint() method
I've gotten freehep export to work by using this syntax:
VectorGraphics vg = new PDFGraphics2D(
new File("temp.pdf"),
new Dimension(x,y));
vg.startExport();
super.print(vg);
vg.endExport();
where 'super' points to the class extending JComponent.
I've also managed to draw an image based on an SVG file using the
example on this page:
<url:http://xml.apache.org/batik/svgcanvas.html>
Using that example I added another button and added this in the
actionPerformed method for that button:
VectorGraphics vg = PDFGraphics2D(
new File("test.pdf"),
svgCanvas.getSize());
vg.startExport();
svgCanvas.print(vg);
vg.endExport();
This syntax gives a couple of NullPointerExceptions.
I also tried to use the graphicsnode of the SVGCanvas by using this syntax:
svgCanvas.getGraphicsNode().paint(vg);
but this gives these two error messages:
PDFWriter: PDFRef 'Paint0' is used but not defined.
PDFWriter: PDFRef 'Paint1' is used but not defined.
Do you have any experiences with these libraries, or other similar
libraries that will do the same thing? I really need this converter to
work as soon as possible. I'm kinda on a deadline here :)
