Need to encode Infrared Data

[Cyrille-de-Brebisson]

Hello,

Could this be used to encode a single channel IR image?

Could it be used to encode an image with RGB + IR? (ie, could I use the A channel for IR data?)

Thanks,
Cyrille

single channel can be done. It's not optimal but fairly straightforward

however the format is optimized for constant alpha so using alpha as a full fledged fourth color channel will degrade the compression a lot.
