Some components which provide reader and writer implementations for open file formats, are released under a more permissive BSD-2 license which enables non-GPL third party software. For a complete list of which file formats are included in the BSD license, see the BSD column of the supported formats table. Developers of non-GPL software wishing to leverage Bio-Formats components not covered by the BSD license may purchase a commercial license from Glencoe Software.
