Yes. there are of course. libwebp, libjxr are available on linux based systems and also seem available on mac and Windows. [1] Both are BSD license so that there is no license issue to port them for any platforms if necessary. I’m not telling about inventing new wheels for them, but adding a kind of a glue layer in webkit as png, gif and png supports do. ;) (e.g PNGImageDecoder.* JPEGImageDecoder.*) [1] https://developers.google.com/speed/webp/download <https://developers.google.com/speed/webp/download> https://jxrlib.codeplex.com/releases/view/107208 <https://jxrlib.codeplex.com/releases/view/107208> https://packages.debian.org/wheezy/webp <https://packages.debian.org/wheezy/webp> https://packages.debian.org/sid/utils/libjxr-tools <https://packages.debian.org/sid/utils/libjxr-tools> ChangSeok > On Mar 20, 2015, at 2:21 PM, Myles C.
