class TaskJuggler::Painter::FontMetrics

Class to compute or store the raw data for glyph size and kerning infomation. Developers can use it to generate FontData.rb. This file contains pre-computed font metrics data for some selected fonts. This data can then be used to determine the width and height of a bounding box of a given String.

Developers can also use this file to generate FontData.rb using prawn as a back-end. We currently do not want to have prawn as a runtime dependency for TaskJuggler.
