dian hina updated BATIK-1014: ----------------------------- oke finish > Valid input arcs produce non-rendered SVG arcs > ---------------------------------------------- > > Key: BATIK-1014 > URL: https://issues.apache.org/jira/browse/BATIK-1014 > Project: Batik > Issue Type: Bug > Components: SVGGraphics2D > Affects Versions: 1.7 > Environment: Operating System: All > Platform: PC > Reporter: rolf.sigg > Assignee: Batik Developer's Mailing list > Attachments: AlmostCircleArc.java > > > In some situations, pie charts produced using JFreeChart and SVGGraphics2D > are rendered empty. Root cause is that the SVG spec states that elliptical > arcs with identical start and end point are omitted > (http://www.w3.org/TR/SVG11/implnote.html#ArcOutOfRangeParameters). > However, the input Arc2D is ok, it is rendered perfectly e.g. to a bitmap > image. The attached code sample produces both bitmap and SVG. > Increasing the numeric precision may help, but does not solve the problem. > There will be a case in which rounding effects will lead to identical start > and end points. > A possible approach could be to switch to circle based on the rounded points > (SVGGraphics2D switches to circle if the Arc2D describes a perfect circle). -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: batik-dev-unsubscr...@xmlgraphics.apache.org For additional commands, e-mail: batik-dev-h...@xmlgraphics.apache.org
