ImageReader using jpgd under GPL 3.0 license #69

Closed senniraf closed 6 years ago

senniraf commented 6 years ago

Hello,

the class ImageReader is using jpgd which is released under the GPL 3.0 License. This means you cannot release this library under the Apache 2.0 due to the conditions in the GPL License. Can you please change the used jpg decoder?

Errr, which source files or linked libraries do you think are under GPL?

I believe the jpgd files in this repository came from Rich Geldreich's jpeg-compressor which have clearly been contributed to the public domain. This is indicated both in the repository I've just referenced, and also clearly written at the top of source files themselves:

Oh sorry. You are totally right. I've thought you got this source-file from this project: https://github.com/kornelski/jpeg-compressor.
