ScanFont 5.0 for Mac could be downloaded from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This Mac app is an intellectual property of Fontlab. We recommend checking the downloaded files with any free antivirus. The program lies within System Tools, more precisely Fonts.
From the developer:
ScanFont takes bitmap images such as photos, scanned handwriting samples, clipart, removes the background; separates the characters; autotraces the glyphs into vector characters; and exports them into a TrueType, OpenType or Type 1 font where they can be edited by a font editor. ScanFont is a plugin for Fontlab's series of font editors - TypeTool, FontLab Studio, and AsiaFont Studio.
