Tilman, The TIlingPaint object has attributes of a TexturePaint and a PatternMatrix.
In my case, the TexturePaint has a BufferedImage, and four attributes: sx, sy (values 0.2439,0.2439) and tx, ty (values 0.0,0.0). The PatternMatrix is just an identity matrix. I can get the Rectangle2D for the shape to be painted. From all of that, what would be the coordinate increments to draw the image across the shape? Is there an example in the PDFBox code that draws a pattern when outputting to renderImageWithDpi()? Rich *** Tilman, Yes, this is the same project from last year. I suspended it in the interim for other priorities. It's still a goal for us, SVG is a much better, scalable representation of many PDF documents. We are getting really close to having it be a good solution. I'm going to experiment with doing the pattern across the range block of the shape. Hopefully that will handle this issue.
