oh, oeps, idd typo, it was redirecting to autoHint instead of stemHist… (will be fixed in the next update)
stemHist takes a binary path as argument.
and has optional arguments:
useCurves=bool: Include stems formed by curved line segments; by default, includes
only stems formed by straight line segments.
blueZones=bool: Return alignment zone report rather than stem report
this is a Adobe FDK tool.
The mojo module is just a collection of useful internal modules. You can also use this:
from lib.tools.compileTools import stemHist
print stemHist("binaryPath.otf", useCurves=True, blueZones=False)
good luck
