1.3 (2021-01-27)

New features and improvements:

  • Added new layout command (#168)

    This command automates the page layout process on a specified the page size by centering the geometries (with customizable horizontal and vertical alignment) and optionally fitting to specified margins. It intends to supersede write’s layout options (i.e. --page-size and --center) in more intuitive way. In particular this command acts on the pipeline rather than on the output file so its effect can be previewed with the show command.

  • (Beta) Complete rewrite of the viewer underlying the show command (#163)

    • fully hardware-accelerated rendering engine

    • smooth zooming and panning, with touchpad and mouse support

    • preview mode with adjustable pen width and opacity

    • outline mode with optional colorful and point display

    • optional pen-up trajectories display

    • per-layer visibility control

    • interactively adjustable display settings

    Note: This new viewer is a beta feature and will evolve in future versions. Your feedback is welcome. The current, matplotlib-based viewer is still available using show --classic.
