What I had in mind, was a shortcut on the way from Graphics 2D to PDF.
Up to that moment, I had used SVGGraphics2D to create SVG
and FOP to turn this SVG into PDF.
For a simple sample scene this transformation took 520 seconds with FOP
0.18.
FOP 0.19 gave a boost to only 12 seconds.
And it's mere 2,5 seconds if I paint to PDFDocumentGraphics2D directly.
I simply snatched a few lines from your PDFTranscoder:
PDFDocumentGraphics2D pdfGenerator =
new PDFDocumentGraphics2D(true, stream, width, height);
pdfGenerator.setSVGDimension(w, h);
GraphicsNodeRenderContext rc = getRenderContext();
pdfGenerator.setGraphicContext(
new org.apache.batik.ext.awt.g2d.GraphicContext());
pdfGenerator.setRenderingHints(rc.getRenderingHints());
// Ask the component to render into the PDF Graphics2D implementation.
((Graphics2D)pdfGenerator).setClip(0, 0, width, height);
component.export((Graphics2D)pdfGenerator, pageFormat, false);
I'll have to tune it a bit,
and I don't quite understand everything yet that's happening behind the
scenes,
but the PDFDocumentGraphics2D is great.
I wonder, why the PDFTranscoder can do without a call to setClip.
If I don't add this line in my code, there's a NullPointerException in
PDFGraphics2D.writeClip().
