We're currently in the process of vetting out Batik 1.5 (after many months of using 1.5-beta4) for our eLearning project. In the transition from beta3 -> beta4, there was the following bug fix:
Adding/Removing children no longer invalidates entire parent region.
This fixed a serious performance problem for us in the JSVGCanvas. We're using it to do whiteboard-like drawing, and after 2-3 seconds of drawing, the mouse response time became very poor, and continued to worsen as more drawing was done. Essentially as the SVG doc became more complicated, dynamic screen update suffered. Beta4 fixed this for us, but now with Batik1.5 it seems to be back. Can anyone comment on this?
Thanks for your time.
PS: tried searching for this old fix on bugzilla but came up empty. It IS mentioned in the release notes at http://xml.apache.org/dist/batik/README.txt.
PPS: what's up with the mailing list server? I tried twice to subscribe but my "please reply to this email to confirm" never seems to have succeeded.
