DWA compression in OpenEXR 2.2
"The default Compression Level setting is 45.0, which creates a visually
lossless image that is often less than half the size of its truly lossless
Piz counterpart. "
So, I included it in my OpenEXR patch ....
Not sure if you can call ILM library to do pixel format conversion so B44 will
finally work?
Time to more research!
