BitFonter 3 cannot recognize FontLab Studio 5 or TypeTool 3 as a "FontLab Server"
Instead of having a live link between BitFonter and the font editor app, use the VFB file format as an intermediary.
Open BitFonter 3
- Click Tools / Options or BitFonter / Preferences.
- Click Outline Font Editor.
Enable Export outline font into VFB file.
Now, when you click File / Export / Outline Font or Outline Pixelfont, and click OK, the app will ask you for a location of the VFB file to save. After you save the VFB, open it in FontLab Studio or TypeTool.
