I'm pretty sure this is a bug, but I guess there might be something
special about how svg markers are handled when rendering to PDF so I
thought I should run it by here first.
I have an SVG file that renders properly when viewed with the Adobe 3.0
viewer, with batik 1.5.1 squiggle and if included as an external-graphic
it generates properly using fop.0.20.5. If I run the same .fo and .svg
through fop 1.0dev I see two sets of problems. First, if there is a
positive SVG translation being applied and stroke-opacity is 0 the
marker position is off. Second, if the translation is negative then
both the line and marker positions are incorrect and if in addition
stroke-opacity is 0 then the markers are not displayed at all. I know
it sounds a little weird. The best thing is to run it and look at it.
(code included below)
Is there, by chance, something special I need to do with my .svg or .fo
to get this to work properly with fop 1.0dev?
Thanks!
