  • This line was added.
  • This line was removed.
  • Formatting was changed.

...

  • KIELER Layout Algorithms
    • KLay Layered's layout option Properties.MERGE_PORTS was renamed to Properties.MERGE_EDGES. Its ID was changed from de.cau.cs.kieler.klay.layered.mergePorts to de.cau.cs.kieler.klay.layered.mergeEdges.
    • Similarly, KLay Layered's layout option Properties.MERGE_HIERARCHICAL_PORTS was renamed to Properties.MERGE_HIERARCHICAL_EDGES. Its ID was changed from de.cau.cs.kieler.klay.layered.mergeHierarchicalPorts to de.cau.cs.kieler.klay.layered.mergeHierarchicalEdges.

    • The de.cau.cs.kieler.klay.layered.distributeNodes property was renamed to de.cau.cs.kieler.klay.layered.wideNodesOnMultipleLayers and allows for two modes now.

      • CAREFUL avoiding node/edge overlaps

      • AGGRESSIVE often more compact but does not guarantee to avoid node/edge overlaps

New Features Included in 2014/12

...

  • KIELER Layout Algorithms
    • A new interactive node placement algorithm in KLay Layered keeps the y coordinates of nodes intact if they don't overlap. This node placement algorithm is supposed to be used together with the interactive implementations of the other layout phases.
  • KIELER Lightweight Diagrams

    • KLighD now ships a generic graph visualization that allows to inspect the structure of graphs specified in any format that is supported by KIML.

    • The wizard for new KLighD projects received some love. We polished it's UI and generated code and added some tooltips.

    • We replaced the Batik SVG exporter with a customized exporter that is based on FreeHEP.

      • It supports semantic data to be added to the generated SVG.

      • Color gradients obey to the specified rotation angle.

  • KGraph Editor Product contains two new features.

    • Layout options can now be configured using a textual DSL.

    • GrAna analyses can be specified using a textual DSL and executed either via the UI or headless.

Important Bugs Fixed in 2014/12

...

  • KIELER Layout Algorithms
    • Computing layouts with the layout direction set to UP failed for compound nodes in KLay Layered.
    • KLay Force allowed the object spacing to be zero, which does not make sense and, more importantly, crashed the algorithm.
  • KGraph Text
    • Converting KGX files into the KGT format failed when certain properties were set.
  • KIELER Lightweight Diagrams
    • We fixed an issue where the allocated memory of views was not released properly.
