Fedora Artwork Guidelines
There are basic rules and guidelines that all artwork in Fedora must follow. We have outlined many of them below. Other rules may also apply.
- Submissions should be made in formats that can be read by software available in Fedora Core and Fedora Extras. Preferred image formats include SVG and PNG. Preferred sound formats include WAV, FLAC and OGG Vorbis. Master files, which may be further edited, should be maintained in non-lossy formats. Preserving vector graphics, raster layers and channels is important for such materials.
- No Fedora artwork should contain hats, particularly fedoras. This is a matter of respect for our biggest sponsor, Red Hat, Inc., and is not negotiable. Of course, passive appearance of hats, such as those upon heads in a crowd, may be tolerable.
- All contributions must be covered by the Contributor License Agreement . We cannot accept contributions from individuals who have not signed the CLA in the Fedora Account System . The CLA allows us to properly license artwork submissions for distribution with Fedora Core and other Fedora projects.
