Subject cvs commit: xml-batik/sources/org/apache/batik/gvt/renderer DynamicRenderer.java
Date Tue, 19 Feb 2002 18:01:29 GMT

  Modified:    sources/org/apache/batik/bridge RepaintManager.java
                        SVGImageElementBridge.java

               sources/org/apache/batik/gvt/renderer DynamicRenderer.java
  Log:
  1) The 'image' element now respects xml:base. (candidate fix for 1.1.2 release)
  2) Fixed a bug where some antialiasing was not always cleaned up in animation
  3) DynamicRenderer now uses RectListManager for dirty regions.
  4) Fixed a bug in one of the constructors of RectListManager.
  5) GraphicsNodeRable now drops it's cached GraphicsNodeRed if the bounds
     of the asociated GraphicsNode change.
  6) Updated Tracker no longer enters the same dirty region twice when an
     object suddenly starts having bounds.
