B.7 Ogham v1.1, August 2005

  1. Improvements to depictions of reactions, including the display of a ``reaction arrow'' between the reactants and products.

  2. Bonds may now be colored independently of the atoms they connect.

  3. An improved algorithm for the placement (north, south, east or west) of implicit hydrogens in atomic labels.

  4. Carbon atoms in strange valence states (such as radicals) are now displayed with a label (including implicit hydrogen count).

  5. Attachment point atoms read from MDL file formats (such as .mol, .rxn and .sd) are now displayed with the attachment index, i.e. "R2", instead of just "R#". This matches the behavior of MDL's ISIS Draw.

  6. A new OEDepictIsLicensed API point to determine whether the Ogham co-ordinate generation and image rendering functionality is available to an application.

  7. Additions to the internal ring template dictionary.
