Changeset 162 in tspsg-svn for trunk


Ignore:
Timestamp:
Apr 14, 2011, 9:30:23 PM (14 years ago)
Author:

Message:
  • NEW: Solution graph size can now be controlled using Output/GraphWidth? setting in tspsg.ini (see ticket:8). Value is in centimeters.
  • NEW: Support for embedded base64 encoded images when saving solution as HTML (closed ticket:4).
  • Renamed Output/ShowGraph? setting to Output/GenerateGraph?.
  • Made some other small tweaks and fixes.
  • FIX: Solution graph is still exported to HTML when graph generation is disabled (fixed bug:9).
