Font Inspector is an analytics script for FontLab and RoboFont. It generates a comprehensive overview of design and metrics of all open fonts into a single HTML file.
How does it work?
- Install: Download FontInspector.py script and place it to your application script folder.
- Select Fonts and Glyphs: Open all fonts you wish to inspect and select few glyphs in one of them.
- Run: Run the script and it will generate a HTML file in the current font's folder.
- Inspect: Open the HTML in your browser, preferably Google Chrome.
←→: Overlay Alignment
Space: Toggle Color
Esc: Reset All Settings
Some outlines don't show their startpoints, why?
Outlines without startpoints are components.
Why are some overlays red?
The outlines are incompatible. However, some incompatible glyphs might still show up as compatible. This is because sometimes it is not possible to determine compatibility just with math. See next answer for a solution.
How can I fix incompatible outlines?
Why are some bars red?
In range of styles from light to bold, sidebearings usually shrink and widths grow. If this expected progression isn't found, the bars are highlighted with red color. However, it doesn't necessarily signal an error, there are many exception to the rule.
Why are some bars grey?
Grey color represents negative sidebearings.
