In Part I, I showed how to hack some code together that allowed you to paste images directly from the clipboard (e.g. from a PDF) into Beda's BKChem, a 2D drawing program. The magic conversion from image to chemical was done by Igor's OSRA.
Well, Igor has taken this idea and run with it. The latest version of OSRA now includes plugins for BKChem, Symyx Draw, MolSketch and Pipeline Pilot.
If you use the Windows installer, the Symyx Draw plugin is automatically installed and adds an "Import Structures from OSRA" option to the File menu. The first time you choose it, you will need to change the path to something like "C:\Program Files\osra\osra.exe" under "Settings...". Here's the plugin in action:
Note that the other plugins appear to be only available from the Windows .zip release.
