iPhone's DNG files can’t be opened #3
Description
When I use the LibRaw Wasm you compiled to open a DNG file from an iPhone, I get results like the one shown in the image. Do you have any idea what might be causing this? Could it be that the iPhone used JPEG-Lossless compression, which LibRaw doesn’t support?
