Hi Paul, I don't think we can apply this patch directly for a number of reasons. Although there are parts in it with value that should be put into cvs when you have finished.
The patch should be done against cvs rather than what you did which seems to be in reverse anyway (I suppose this is what you are working on). It's better to avoid the various formatting changes which really confuses things. Using temp files can cause problems in certain situations. I don't see the need for an extra PDFStreamGraphics2D class. Modifying the PDFGraphics2D should suffice. An extension may work better in this situation with the development code. If I understand the problem properly. Thanks, Keiron. On Mon, 2002-05-20 at 17:43, Paul Reavis wrote: > Attached are gzipped diffs for the changes I made vs. the 0.20.3 > release.
