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 pts).

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)
