Text rendering

Provok

Text Renderer written in Rust using HarfBuzz for shaping, FreeType for rasterization and OpenGL for rendering.

Input

Provok is fed with a JSON file that consists of an array of word alongside their display parameters (fg_color, boldness, italic, etc.):

{
    "font_size": 50,
    "words": [
        {
            "text": "\"PROVOK\"",
            "canvas_color": "#E24E43",
            "bg_color": "#EFB715",
            "fg_color": "#E24E43",
            "bold": true
        },
...
}

How To Use

First, you need to have installed the Rust toolchain and HarfBuzz on your machine, then:

git clone https://github.com/o2sh/provok --depth=1
cd provok
make install
provok

You can also provide your own custom input file with the --input CLI flag:

provok -i /path/to/input-file

You can specify the frequency (in frame per second) at which the word will appear using the --frequency CLI flag:

provok -f 5
