FontEdit is a desktop application that allows you to convert general-purposefixed-width desktop fonts to byte array representation that's suitable foruse in embedded systems displays.

It's written in C++ with Qt UI and was tested on Windows, Linux and MacOS.

Read more about it inthe blog post.

With FontEdit you can:

• import fonts from the operating system - to load a custom font, you shouldfirst register it in your OS,
• edit individual font glyphs after importing - automatic import is a best-effortoperation and although the font should be usable right after importing, youmight want to tweak it so that it looks better,
• add new glyphs to a font document - either by copying an existing glyph, startingfrom scratch or adding a glyph from a character you input (useful for addingnon-ASCII characters to your font),
• export the font as source code (in a form of byte array) suitable for Arduino,C/C++ or Python,
• save your progress to a file - the font document file is cross-platform so you cane.g. import and edit it on MacOS and then move to RPi and export the code from there,
• as of 1.1.0 you can do partial exports, i.e. export only a bunch of font charactersthat you really need for your application (read more inthis blog post).

You can edit font glyphs with a minimal editor that's controlled with a mouseand keyboard. Click and drag the mouse to set pixels (making them black), holdAlt or Ctrl (⌘) to erase. Use touchpad scroll (mouse wheel) with Ctrl (⌘) to zoomthe editor canvas.

You can also reset the current glyph or the whole font to their initial state(from latest save). The editor supports Undo/Redo for most operations.

The font data can be exported to:

• a C file (also suitable for use with C++),
• an Arduino-specific C file (using PROGMEM),
• a Python list or bytes object (both compatible with Python 2.x/3.x and MicroPython).

You can switch between MSB and LSB mode, invert all the bits, and conditionally includeline spacings in font definition (not recommended unless you have a very good reasonfor it). The tab size can be configured.

TheReleases GitHub page containspackages for:
