2.10.3 Previewing Path Oset
Via View > Show Preview Oset, you can toggle a grey preview of
the oset the Oset Paths filter would produce with its current
settings. This is useful for an open paths workflow. For the
preview to take eect, Filter > Oset Paths must have been run
at least once. The preview only applies to the current glyph.
2.10.4 Previewing OpenType Features
You can activate and deactivate features for previewing
through the Features menu at the bottom left of the window
in Edit view:
You may need to recompile the features before they are
available in the pop-up list. You can select any number of
features concurrently, and deselect all of them at once by
choosing the dash at the top of the menu.
In Edit view, Glyphs can only show a preview of
substitution features, since positioning features can be
handled very dierently in dierent application and system
environments. To test positioning features, it is therefore
recommended to make use of the Adobe Fonts folder.
For details, please see section 2.10.7, ‘Previewing in Adobe
applications’ (p. 32).
2.10.5 Previewing Interpolated Instances
Click on the Preview button next to the Features pop-up.
The window content will be sectioned vertically, the Edit
view at the top, the Preview at the bottom. Pick an instance
from the instances pop-up next to the Preview button to
see a live interpolation of the respective instance in the
Preview area. Drag the separator line to adjust the size of
