[feature] Decode Apple ProRAW LosslessJPEG #10

Closed syoyo closed 3 years ago

syoyo commented 3 years ago

Apple ProRAW uses 12bit LosslessJPEG

I found there is an issue which fails to decode when predicator is 7.

Patch will be soon provided in proraw branch.

Primarily with this fix(need to lookup previous pixel's channel value)

https://github.com/syoyo/tinydngloader/blob/a49bcbbabab05779ba3cb0d990b9e862746b9fee/tiny_dng_loader.h#L1094

tinydngloader now can parse Apple ProRAW image. :tada:
