Overview

Glyphtracer takes an image that contains pictures of several letters. It recognizes all them and lets the user tag each letter to a Unicode code point. It then converts the images to vector form and writes them to a FontForge's data format. The font can then be finalized with FontForge.

Dependencies

Glyphtracer requires PyQt5 and Potrace, which is an image vectorizer.

It has been only tested on Linux. It might work on OSX or Windows. It might not.

Usage tips

Glyphtracer only processes 1 bit images, but they can be in any format understood by Qt.

The letter recognition is based on white space. Thus every row must be separated from other rows by a continuous horizontal strip of white. If this is not the case (because, for example, your image is tilted), detection will fail. Similarly letters on a single row have to be separated by vertical white space. Just give your letters lots of "room" on all sides and everything will work.

    refresh metadata to flathub standards

    I saw https://nibblestew.blogspot.com/2021/09/glyphtracer-20.html and wanted to have a play with it myself. So I built up a quick flatpak manifest and generated some modern metadata for better Linux desktop integration. The icon was just quickly generated with https://flathub.org/apps/details/org.gnome.design.Emblem and I in no way feel strongly about it - I just needed a placeholder!

    For flatpak you need a reverse dns style dbus name which I've generated out of the repo here. Again, if you have a namespace you prefer then editing it is very easy.

    An obvious next step would be to put a bit more of a buildsystem around this to install the files in the correct location - for the purposes of flatpak I didn't need that but it'd be more useful for other users.

    If you think this is vaguely useful I'll put the manifest on flathub as this is exactly the kind of rarely changing app where sticking it in a container works well.

    Hi, I just saw you updated Glyphtracer to Qt5 last year. In 2015, I made a fork of GlyphTracer. I think I sent you a mail back then for merging our projects but it might have ended in limbo... If you're interested to look at it, it's there: https://github.com/osp/osp.tools.fons

    I don't recall all the changes I've made. But from what I recall:

    • I replaced potrace with autotrace so that the tracing is made directly with python-fontforge in order to add the scan of the letter in a layer so that one can have it as a reference if s·he wants to modify it in Fontforge
    • I added a font height and font ascent settings so that the scales are good when opening the font
    • I added zoom scales, new characters
    • I added autowidth and autohint
    • I added spacing characters automatically

    In the repo, I added some guidelines to prepare the images for the scanning.

    Hope this finds your interests!

    As I mentioned in https://github.com/jpakkane/glyphtracer/pull/2 this is exactly the kind of app that works well in a container. I'm going to submit it to flathub, would you like to have commit rights there? That means you'll be able to update it if there's a new release and generally be in charge.

    https://github.com/flathub/flathub/wiki/App-Submission has some more information on this if you're interested.
