Hi Nikhil,

Im trying to use the JSVGCanvas to draw an SVGDocument of size about 140KB. The DOM creation and GVT build happen with expected speeds...but the canvas takes about 13 seconds post build to be painted. Is there anything I could do to shorten the TreeRenderer phase or a phase post that? Ive set all text styles="text/plain" which reduced the delay to the current amout.
Well sample content always helps. The two common time sinks I've seen are filters and text. I'll focus on text since you mention it as a time factor, is the time actually spent in the render phase or the rendering preparation phase?
Sys specs: Debian linux on a Dell with a P3(at 1GHz) and Batik1.5.1
A couple of other issues:
a. The canvas seems to interact in a strange way with the JScrollPane. The scrollbars show up sometimes and do not at other times. Is there anyway I could turn the scrolling off on the canvas and ask it to default to the scrollpane.
b. Updating the DOM totally kills performance for me. The update happens fast but then scrolling through the canvas slows down dramatically. Ive worked around this by recomputing the SVGDocument everytime...The updates I make dont change the bounds of anything just the colors. Is there a way to make this faster?
c. A final question...is there anything I could/should do while replacing an ALWAYS_STATIC with another one as far as releasing references goes? Since the update manager is null, Im guessing the GVT doesnt hold an references?
Thanks, Nikhil
