http://issues.apache.org/bugzilla/show_bug.cgi?id=37236 ------- Additional Comments From [EMAIL PROTECTED] 2005-10-25 00:39 ------- Created an attachment (id=16799) --> (http://issues.apache.org/bugzilla/attachment.cgi?id=16799&action=view) Patch for majority of transform issues with patterns/gradients This patch fixes most of the problems with 'simple' gradients and patterns in PDF output. However it does not cover everything there are three major outstanding issues: 1) Gradients with an SVG setting of spreadMethod reflect or repeat, are rendered with just 'pad'. Fixing this requires resorting to rasterizing the content (it might be possible to get around this for linear gradients but certainly not with radial). 2) Patterns that contain gradients generate 'bad' PDF. I suspect the problem is resource referencing. Since I am fairly sure the problem existed before my fidling I'm going to leave it as is. 3) Patterns with 'overflow="visible"' ignore overflow. Number 3 is pretty simple to fix (just need to render the gn content multiple times to make the tile). I suspect Number 2 is not too hard if you understand PDF (which I don't really). Number 1 would require adding support for rasterizing unknown paint's and using that as a pattern fill (just make the size of the pattern fill the same as shape being painted). A few notes on the patch. 1) I simplified the PDFState.Data class, by removing the the 'concatenations' List. It doesn't seem to be used by anything. 2) I changed PDFState.getTransform it now just returns the current transform as this already includes all the previous transforms. Perhaps I misunderstood the code but things work now and the transforms make sense where as they didn't before. 3) I added the ability to provide a transform to PDFFactory.makeGradient this is required to handle some of the more complex cases of gradients with non-uniform scaling transforms. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
