Description Michael Wenz CLA 2010-08-23 03:55:57 EDT

Comment 1 Tim Kaiser CLA 2011-03-08 06:28:48 EST 
Font management introduced on diagram level.

The following changes were made:

1. pictograms model:
    - Diagram has new fonts containment reference
    - for Style and AbstractText the font reference is not a containment   
      reference anymore

2. ga services
    - the methods which create a special form of AbstractText/Style which create 
      a font inherently need an Diagram instance passed, method signature 
      adapted, CLIENT ACION NEEDED 
    - in analogy to the Color management, new manageFont() methods introduced    
      which check if a font with the given attributes exists already in the 
      diagram and only create it as necessary, CLIENT ACION NEEDED

3. migration from 0.7.0 to 0.8.0

3. migration from 0.7.0 to 0.8.0
    - new service Graphiti.getMigrationService(), can be used by tools on 0.7   
      to migrate existing diagrams to the new metamodel structure, note that   
      diagram files written with 0.7.0 can be opened with 0.8.0, but if one  
      serializes again fonts are lost if no migration of the diagram structure 
      is done. The tool developer can decide if an on-the-fly migration or a 
      migrate button etc is appropriate for his tool, 
      POSSIBLY CLIENT ACTION NEEDED

These changes require actions from tool developers which want to migrate their tool from Graphiti 0.7 to 0.8.
