Allow grouping multiple AOVs into a single multilayer OpenEXR file #224

Open dictoon opened 11 years ago

est77 commented 11 years ago

With EXR2 is possible to save images as multipart EXR files. They are much faster to read than traditional multilayer EXR files. You don't need to read all the pixels anymore to extract a subset of the channels. OpenImageIO already supports multipart.

We now have Frame::write_main_and_aov_images_to_multipart_exr(). We need to expose it.
