  • Fixed "rendering" of nodes and edges when using a label detection strategy other than LABEL_DETECTION_NONE.
  • Fixed problems with custom label models (i.e. NodeLabel.CUSTOM_LABEL_MODEL) and label detection strategy LABEL_DETECTION_BY_WRAPPING.
• Removed obsolete dependencies to GraphML extension package in the demo build script build.xml.

ySVG 2.2 - Changes Since 2.1.0.1

Improvements

• ySVG GraphML support no longer depends on the yFiles for Java GraphML extension package but uses the GraphML support that comes with yFiles for Java 2.7.

  1. Improved rendering for printing in landscape orientation.
  2. Improved robustness regarding invalid SVG documents.
• Class SVGDOMEnhancer:
  1. Added new label detection strategy LABEL_DETECTION_NONE to allow to turn off label detection.
  2. Improved robustness of cleanup code in label detection strategies with regard to exceptions.
