John Hewson commented on PDFBOX-1094:
-------------------------------------
I've overhauled the tiling pattern code in 1571482 to support uncolored
patterns as this was the last remaining unimplemented aspect of my work on
color spaces. I've replaced the custom PaintContext with TexturePaint which is
basically AWT's built-in support for tiling paint. I've also changed the way
that the image is rendered from the pattern contents stream to simplify when
and how scaling occurs.
As I mentioned on the dev mailing list, I think we're going to need to abandon
AWT Paint for patterns due to bitmap scaling issues, so I'm trying to reduce
tiling paint to its essence in anticipation of this future change.
