Release Notes ySVG Extension Package

ySVG 2.3 is the latest version of the yFiles SVG extension package.

Technical Requirements

• Graph visualization library yFiles for Java 2.8 version series and Oracle J2SDK 1.4 or higher is needed for software development.
• A browser to view the HTML documentation.

ySVG 2.3 - Changes Since 2.2.0.1

Features Added

• Added support for ignoring selection state when exporting to SVG using modules SVGOutput and SVGZOutput.
• SVGNodeRealizer: Added support for new yFiles for Java 2.8 rendering hint KEY_SELECTION_PAINTING.
• SVGDOMEnhancer: Added new label detection strategy LABEL_DETECTION_BY_RECONFIGURING that works by replacing label configurations.

Improvements

• SVGModel: SVG 1.2 specific elements in SVG documents declared to be conforming to the SVG 1.0 or SVG 1.1 standards are ignored and no longer result in a org.apache.batik.dom.util.SAXIOException.

Bugfixes

• SVGModel: Reading a SVG definition from an URL now tries to determine the appropriate character encoding from the document identified by the URL instead of using the platform default encoding.

ySVG 2.2.0.1 - Changes Since 2.2

Bugfixes

• Class SVGDOMEnhancer:
  • 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.
• Class SVGModel:
  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.
• Upgraded from Batik 1.6 to Batik 1.7. See the SVG Batik page for a list of improvements.

ySVG 2.1.0.1 - Changes Since 2.1

Bugfixes

• Class SVGModel
  • added synchronization to image cache to prevent infinite loops in multithreaded environments
  • estimating image sizes for image caches no longer causes integer overflows

ySVG 2.1 - Changes Since 2.0

Features Added

• Class SVGDOMEnhancer
  • added new default label detection strategy LABEL_DETECTION_BY_WRAPPING
• Class SVGIOHandler
  • added public methods getSVGRenderingHintValue and setSVGRenderingHintValue to allow for user preferences when exporting SVG enhanced content
  • added property useCSS to provide a means to switch between SVG element attributes compacted into a single CSS style attribute and default XML attribute listings
• Class SVGModel
  • substantial rendering performance improvement; see setImageCacheEnabled, setImageCacheSize, setMaximumImageSize, setMinimumRelativeImageSize for related documentation
  • enhanced the internal SVG DOM generating mechanism to accept slightly invalid SVG definitions (e.g. unbound namespaces)
  • added public methods deserializeSVGContent and serializeSVGContent to allow for custom programmatic serialization/deserialization of SVG contents
• Class SVGNodeRealizer
  • YGF serialization now includes SVG content to allow for deserialization without original/external SVG resource file.
• Class SVGNodeRealizerSerializer provides GraphML serialization support for SVGNodeRealizers

Demos

• source code demo RenderingPerformanceDemo has been added
• source code demo GraphMLDemo has been added
• source code demo SVGNodeRealizerDemo has been added
• source code demo SVGNodeDemo has been renamed to SimpleSVGNodeRealizerDemo

Incompatible API Changes

• Class SVGDOMEnhancer: changed visibility of public field labelDetectionStrategy to private
