Sample Code

Full page figures

The following macro allows me to include figures in my document and adjust them to have the size of a normal page.

Feature Requests

  • grid=yes option for \definelayout,
  • temporary user variable for privat macros (see above),
  • macro \defineuvervariable{...} to define namespaces for third party modules.
