toasty is a Python library that helps you create “tile pyramids” from astronomical image data as used in the TOAST format. These multi-resolution maps can be viewed in software such as the AAS WorldWide Telescope.
toasty was originally written by Chris Beaumont, benefited from contributions by Clara Brasseur (Space Telescope Science Institute), and is currently maintained as part of the AAS WorldWide Telescope project.
The easiest way to install toasty is through pip:
pip install toasty
For more information, please see the full toasty installation instructions.

Contributions to toasty are welcome! See the WorldWide Telescope contributors’ guide for applicable information. We use a standard workflow with issues and pull requests. All participants in toasty and the WWT communities must abide by the WWT Code of Conduct.
