Hi Jonathan,

Does batik internally use the builder to build GraphicsNodes or does it always use Documents?
They are always built in the context of a document, otherwise CSS won't work properly.
I have been using this to build child GraphicsNodes of an SVG document so that I can rasterize fragments of it. However, so far its been pretty unsuccessful because all of the 'g' elements have been the wrong size and all the shape nodes (mostly 'polygon') have appeared as black images (although they do seem to be the right size).
I don't think I understand what you mean by "the 'g' elements have been the wrong size". The 'g' elements are aways the union of their descendants bounds.
Can anyone think of a good way to rasterize parts of an SVG document, or a path to develop this functionality with batik?
I would do one of two things, one would be to build the complete GVT tree and then call paint directly on the GraphicsNode that I was interested in having painted or I might set all the other 'branches' of the SVG document to be visibility="hidden" or display="none".
At the very least you might consider building a 'sub' document that includes all the nodes from the root of the SVG document to the element of interest. Without this the 'context' for the subtree many things could be lost (I would suspect that this is why the polygons are black, although that might also be because the coloring is done with a CSS style sheet?) it all depends heavily on the structure of the document in question.
