EOT tools

Tools for working with EOT (Embedded OpenType) font files.

About

Embedded OpenType (EOT) fonts are a font format mostly used in Microsoft applications. The primary usage has been as a webfont in Internet Explorer. Nowadays, it is mostly unused, but when dealing with legacy distributions, we might need a deeper look into their properties. Additionally, tools like Fontello still generate EOT font files by default.

When looking for FOSS tooling around EOT fonts, I could not find any reliable parser that would allow further inspection of these files. With the specification being publicly available and the files basically being a TTF file with some header/prefix, basic processing is rather straightforward. Thus, I decided to write a short script for it to later move it into a library to make metadata/property analysis of EOT possible.

The corresponding TTF files can be analyzed with a much wider variety of tools, for example, using the fonttools library.

Features

• Read all defined properties.
• Retrieve the embedded TTF file data. Currently limited to uncompressed and unencrypted data as this is what the test files I found use.

Installation

You can install this package from PyPI:

python -m pip install eot_tools

Alternatively, you can use the package from source directly after installing the required dependencies.

Usage

To load an EOT file, use the following code:

from eot_tools import EOTFile


eot = EOTFile("Maki.eot")
print(eot.family_name, eot.style_name, eot.version_name)

Once the file is loaded, you can use fonttools to load the actual font for example:

from io import BytesIO

from eot_tools import EOTFile
from fontTools.ttLib import TTFont


eot = EOTFile("Maki.eot")
with TTFont(file=BytesIO(eot.font_data)) as font:
    print(font)
