1.1 What's New in Version 7
Improvements for the Rule Set Development Workflow
• Three new types of variables for classes, features and image object levels facilitate
development of parameters of actions as used in Definiens Architect.
• Undo process editing operations allows you to go back to a previous state in
process editing.
• Find and Replace within rule sets for classes, features, image object levels, variables,
image layers, and thematic layers.
• Organize and save process snippets to a library for reuse in other rule sets.
• Generate a rule set documentation from comments to processes.
• The handling of customized algorithms has been improved concerning the
dependencies of the rule set items. Rule set items and their dependencies are
visualized in a newly structured list. Scope dependencies of rule set items are
applied automatically according to applicable consistency rules.
• A new contrast split algorithm allows segmentation of an image or an image
object into dark and bright regions.
