Class: Antex::SetBox

Inherits:
Measurable show all
Defined in:
lib/antex/set_box.rb

Overview

Encapsulates calculations and results for perfectly typesetting the SVG vectorial conversion of a TeX box.

Three files are required by #load for initialization: [+YAML+ file containing TeX measures] We obtain this by using TeX directly to measure the box and write to file. Required metrics are ht, dp and wd (naturally expressed in +pt+s). [+SVG+ picture fitting tfm metrics] We obtain this by converting the DVI rendition of the box to SVG using +dvisvgm+. [+SVG+ picture fitting the ink] We obtain this by converting the DVI rendition of the box to SVG using +dvisvgm+ with the --exact flag.

After the initialization the calculations are performed immediatly. Six metrics become available:

  • mt, mr, ml and ml (the margins, positive or negative)
  • wd and ht (width and height)
  • ex (the default unit)
