http://issues.apache.org/bugzilla/show_bug.cgi?id=44439 Summary: Quick Successive User-Triggered Animations Cause Batik to Hang Product: Batik Version: 1.7 Platform: PC OS/Version: Windows XP Status: NEW Severity: critical Priority: P1 Component: SVG Viewer AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] I have found what I think is a serious bug in the Batik SMIL animation engine. When an animation's begin and end times are controlled by the user (such as an animation that starts when the user presses a key and ends when the key is released), starting and stopping the animation in quick succession, in a way such as tapping the key repeatedly, will cause Batik to hang. This bug is easily reproduceable. Open the following SVG file in Squiggle: --- <?xml version="1.0" encoding="UTF-8" standalone="no"?> <svg xmlns="http://www.w3.org/2000/svg"; width="400" height="400" id="svg1"> <rect x="0" y="0" height="400" width="400" fill="#0000ff" id="rect2"> <animateColor attributeName="fill" values="#0000ff;#000088;#0000ff" dur="3s" repeatCount="indefinite"/> </rect> <rect x="180" y="180" height="40" width="40" fill="green" id="rect1"> <animateTransform attributeName="transform" type="translate" to="100,0" from="0,0" dur="1s" begin="svg1.mousedown" end="svg1.mouseup"/> </rect> </svg> --- The animateColor on the background rect is needed to make user-triggered animations appear, another bug that deserves its own entry. Copy-and-paste the SVG code above into a file, open that file in Batik, and then click the SVG file repeatedly as fast as you can. Eventually, it will hang. Even if you don't start and stop the animation fast enough to cause the hang, the hang may still occur if there is another animation running that happens to start or end at the exact same time that the user-triggered animation starts or ends. -- 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. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
