Python in FontLab Studio

FontLab Studio 5.1.5 for Mac OS X

FontLab Studio 5.1.5 for Mac OS X works with Python 2.7 (in 32-bit mode) that comes pre-installed with Mac OS X 10.7 and newer, it uses Python 2.7. On older OS X versions (10.5 and 10.6) you need to install Python 2.7 separately. Download the latest version, currently 2.7.10.

Note: FontLab Studio 5.0.4 for Mac OS X 10.6 and older (a PowerPC app) works only with Python 2.3.

FontLab Studio 5.2.2 for Windows

FontLab Studio 5.2.2 for Windows works with a 32-bit version of Python 2.7. Even if you use a 64-bit version of Windows, you need to download and install the 32-bit version of Python 2.7.x for Windows.

  1. Download the latest 32-but version of Python 2.7 for Windows, currently 2.7.10.
  2. Run the setup.
  3. We also recommend that you download and install the Python for Windows extensions. Remember to pick the version that matches your Python version.
  4. Visit python.org to download additional modules and documentation.

Note: the old FontLab Studio 5.0.4 for Windows works only with Python 2.4.

How FontLab applications use the Python macro language  - and some useful scripts

The Python macro language is a really powerful tool that can save you loads of time in performing tedious tasks. Need to add a bevel to all the characters in your font? A Python macro can do it in a flash. Want to rename all your fonts to add your foundry intials? Do the whole library in seconds with a macro. Got an idea for a new FontLab tool? Write it in Python and add it to the FontLab menus.

Note: Installation instructions

Please refer to our Python FAQ entry for detailed instructions (valid as of 2014) on how to install RoboFab, fontTools, dialogKit and Vanilla in FontLab Studio 5.1.x/5.2.x.

  • RoboFab by Tal Leming, Erik van Blokland and Just van Rossum
    Python library that provides an independent font development environment that integrates with FontLab Studio and can be used for font, glyph and metrics manipulation. Free for Mac OS X and Windows. RoboFab requires NumPy (Mac installer on PythonMac) and FontTools TTX.

  • FontTools TTX by Just van Rossum
    & Behdad Esfahbod. Low-level OpenType table editing package written purely in Python. Free for Mac OS X and Windows.

  • Adobe FDK for OpenType (AFDKO) by Adobe Systems
    Set of high-quality OpenType conversion, editing, production and quality assurance tools, partly written in Python and integrated with FontLab Studio. Free for Mac OS X and Windows.

  • FontQA by FontShop International
    Font quality assurance framework and test suite for FontLab Studio written in Python and published by FontShop International, allows performing consistency checks across fonts within a font family. Free for Mac OS X and Windows.

  • Autopsy by Yanone
    A FontLab Studio add-on written in Python for analyzing design consistency across multiple fonts. It visualizes a selection of letters side by side and puts it into a PDF for visual comparison. If visual comparison isn't enough for you, it dissects what's there and what's not and puts that into simple graphs. Free, for Mac OS X and Windows. Requires ReportLab.

  • FeatureProof by Tal Leming
    FeatureProof is an application for testing built on top of Compositor that makes it easy for type designers to test OpenType Layout features in fonts. Free for Mac OS X.

  • Font Remix Tools by Just Another Foundry
    A set of plug-ins for FontLab Studio written in Python that allow scaling of glyphs without affecting the stroke weight.Free for non-commercial use, licenses 99-396 EUR, for Mac OS X and Windows. a set of plug-ins for FontLab Studio, that allow scaling of glyphs without affecting the stroke weight. They allow to:
  • tune the width, height and weight of
    single letters interactively  
  • automatically generate small caps
  • generate superiors, inferiors, numerators and denominators
  • create true condensed and extended versions
  • generate tabular figures with only a couple of clicks
  • slant glyphs while keeping vertical tangents straight

  • Superpolator by Erik van Blokland
    Professional typedesign is complex enough as it is: Superpolator breaks free from the conceptual constraints of Multiple Master: work with any number of axes, insert masters where you need them and define, generate all the weights you want. Glyph specific axes, split locations, intermediates, powerful extrapolation. Licenses 250 EUR and up, for Mac OS X. Requires RoboFab.

  • PixelBrush by Gustavo Ferreira
    A simple tool to draw outline pixel fonts in FontLab Studio. Free for Mac OS X and Windows.

  • Compositor by Tal Leming

  • removeAnchors and removeSelectedAnchors remove either all the anchors from a font or the anchors on selected glyphs in a font.
  • buildAccents will build accented characters from glyphs which have anchors.
  • betterGenerateFont will make a copy of the font you are working on, remove its overlaps and decompose its characters, then give you the choice of font type to generate.
  • Guidelines show how one can add and remove guidelines to a vfb file.
  • copySidebearings will copy the sidebearing values from one vfb to another. copySidebearingsToMaster will copy the sidebearings from a font to a specified master in a MM vfb.

Python Background

Python is an interpreted, interactive, object-oriented programming language. It is often compared to Tcl, Perl, Scheme or Java. Originally developed by Guido van Rossum in 1990 it is an open source language and has gained popularity rapidly. For this reason we chose it as the scripting language for FontLab 4 macros.
