The tiled image being used is rotated and the co-ordinates are inverted compared to Java2D. We have already altered the Transformation matrix to map PDFspace onto Java2D space. We then need to map the image onto 'PatternSpace'. We could not see how we could easily do this so we overrode createContext to create a single image, plotted the images onto this and then used the standard TexturePaint functionality. >> Our custom PaintContext creates a single image and works out the >> tiling repeat offsets so it is drawn correctly. > In any case you seem to be describing a situation where the TexturePaint > doesn't perform the operation you need it to perform.

Since there is only 1 method > in the Paint interface, you could simply change your class from "extends > TexturePaint" to "implements Paint" and you should be set, no? We will have a look.
