Agenda:

Key Dates for Review:

Discussion:

• Google Summer of Code ideas:
• Add support for bfloat16
• Is adding a new pixel type safe to do? There’s support for adding a new compression type. But it may not be the same for pixel type.
• Add a part type that is only metadata. 
• A fast header read
• So you don’t have to read the file to get to the header data.
• Add support for sorting of attributes.
• Peter: I’ve never grasped why people want to change the order.
• Larry: They don’t. The only thing you get is alphabetical, which isn’t always what you want. 
• Peter: an ordering attribute that tells the order. They’re written and read in alphabetical order is they’re stored internally in a map that keys off the name.
• You can write any order you like, but you can’t ask the API what order they’re in.
• Joseph: If attributes are written in alphabetical order, would identical files checksum to the same value?
• Kimball: They are, because they’re a map.
• Peter: But compression data is not the same.
• Convert boost python to pybind11. 
• Explore other compression schemes. 
• Should try Zstandard.
• Performance metric suite.
• A new spectral attribute type.
• Alban’s github repo looks nice.
• Switch c++ library to use the C core.
• Kimball:: I started working on ImfHeader. You can blindly copy a Header object
• Most hated github question: doesn’t build on fedora, i386, yada yada
• CMAKE_PREFIX_PATH:  This is, in fact, the proper way to direct OpenEXR to an Imath installation.
• For python cmake issues, we should look at OTIO does.
• #1201 Extend multipart RgbaInputFile API
• After merging #1194, there are conflicts. Peter will investigate.
• Peter: I can’t reproduce some of the OSS-fuzz issues. And some have been closed without any fixes. Something must have changed internally with the fuzzing system.
