# FontEdit
FontEdit is a desktop application that allows you to convert general-purpose
fixed-width desktop fonts to byte array representation that's suitable for
use in embedded systems displays.
It's written in C++ with Qt UI and was tested on Windows, Linux and MacOS.
Read more about it in [the blog post](https://kapusta.cc/2019/03/20/fontedit/).
## Features
With FontEdit you can:
* import fonts from the operating system - to load a custom font, you should
first register it in your OS,
* edit individual font glyphs after importing - automatic import is a best-effort
operation and although the font should be usable right after importing, you
might want to tweak it so that it looks better,
* add new glyphs to a font document - either by copying an existing glyph, starting
from scratch or adding a glyph from a character you input (useful for adding
non-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 can
e.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 characters
that you really need for your application (read more in
[this blog post](https://kapusta.cc/2020/05/31/fontedit-1-1-0)).
### Font Editor
You can edit font glyphs with a minimal editor that's controlled with a mouse
and keyboard. Click and drag the mouse to set pixels (making them black), hold
Alt or Ctrl (⌘) to erase. Use touchpad scroll (mouse wheel) with Ctrl (⌘) to zoom
the 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.
### Source Code Export
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 include
line spacings in font definition (not recommended unless you have a very good reason
for it). The tab size can be configured.
## Getting FontEdit
### Packages
The [Releases GitHub page](https://github.com/ayoy/fontedit/releases) contains
packages for:
* Ubuntu/Debian (amd64),
* Raspbian Buster (armhf),
* MacOS,
* Windows.
### Building from source
Prerequisites:
* Qt (tested with >= 5.9)
* cmake (3.9 or newer)
* C++ compiler that supports C++17
Follow these steps to build the app from the source code:
1. Clone the Git repository:
```
$ git clone https://github.com/ayoy/fontedit
$ cd fontedit
```
2. Check out Git submodules:
```
$ git submodule update --init
```
3. Build with CMake:
```
$ mkdir build
$ cd build
$ cmake -DCMAKE_BUILD_TYPE=Release ..
$ make
```
4. (Optionally) Install on Linux with: `make install` or create a dmg
image on MacOS with `make dmg`.
