Revision 1.12 - (hide annotations)
Sun Aug 15 16:58:22 2004 UTC (13 years, 2 months ago) by bertho
Branch: MAIN
CVS Tags: REL_1_5_0
Changes since 1.11: +14 -9 lines
- Added drawing of partial trees. You now can select a subtree based on a
  revision number, branch number or symbolic tag to show only that part of the
  tree. New config option branch_subtree selects which part is shown. If the
  subtree is empty, then the whole tree is shown.

- Most error and warning messages are now displayed in the graph, instead of
  being written to stderr. This enables you to see an image eventhough errors
  might be present. The old method would generate a corrupt image.
  New configuration options include msg_color and msg_font to control the looks
  of it. Messages are always printed at the bottom of the image.

- Fixed a bug in the folding code where subtrees would not fold correctly.

- Added diff links in the map-generation for detected merges so that you can
  get the differences in merge-operations. The options map_merge_href and
  map_merge_alt must be set accordingly.
