Now Glyphs users can also have red arrows!
This plugin points at possible outline errors, like FontAudit in FontLab Studio. This version works in Glyphs 3 and newer.
When the plugin is active, red arrows will point to possible mistakes in your outlines.
These kinds of errors are detected:
- Missing extremum points
- Fractional coordinates and transformations (dependent on your grid settings)
- Nearly smooth connections
- Empty segments
- Short segments
- Collinear vectors
- Semi-horizontal and semi-vertical lines
- Zero handles
- Spikes
Use the Plugin Manager.
But now that you’re here, you are probably looking for manual installation. Download the complete ZIP file and unpack it, or clone the repository.
Double click the .glyphsReporter file and confirm the dialog that appears in Glyphs.
Restart Glyphs.
Open a glyph in Edit View. Use View – Show Red Arrows to toggle the arrows.
You can set the size of the arrows, e.g. to 10 pixels by running this command in the Macro Panel:
Glyphs.defaults["de.kutilek.RedArrow.arrowSize"] = 10In the glyph view, open the context menu and choose Hide Error Labels/Show Error Labels.
Go to the Font overview tab and choose the master you want to check. Use Edit – Select Glyphs With Outline Errors to select affected glyphs, then add a mark color to them, make a new list filter, or open a new tab. Whatever you like best that allows you to step through the glyphs and fix the outline errors.
