This script shows the way to get to the font level postscript hint values.
|

These values were available from the fl layer, but not in RoboFab.
|

Now they're available in RoboFab in a slightly easier to use format.
|
|
The values also export to UFO and import from UFO.

|

Check the FontLab FontInfo panel / Hinting Settings
