License Restrictions: SixLabors.ImageSharp is not 100% permissive #306

Open sangeethnandakumar opened 1 year ago

Your port works very fine. But this uses SixLabors.ImageSharp & SixLabors.Fonts which are not very permissive and requires commercial licenses.

License link: https://github.com/SixLabors/ImageSharp/issues/1024

Since they're very restrictive in usage, Can they be replaced with any more open source MIT based image and font libraries

Great work anyways ..!

Better migrate to: SkiaSharp

It's 100% open source MIT licensed Has most options as ImageSharp Is supported and used in Microsoft MAUI projects as well

ImageSharp is licensed under Apache License 2.0, which is very permissive.

sangeethnandakumar commented 1 year ago

But this project is MIT licensed. Still we can't use for commercial projects because of it's dependency is not fully permissive Apache 2.0. We can't sell a software without exposing source code as per there license terms

sangeethnandakumar commented 1 year ago

There commercial licensing is AGPL which is not very permissive. image

There commercial licensing is AGPL which is not very permissive.

Please read the very first line in that post; the actual license is Apache 2 which does NOT require disclosing sources.

However ImageSharp will be changing its license again for v3.0, see this issue for more details.
