Hello, we've just done a feature-freeze ready for the release of libvips 8.18. There's a tracking issue here:
libvips/libvips#4770
The new bit of API is get_gainmap():
https://github.com/libvips/libvips/blob/master/libvips/iofuncs/header.c#L1069-L1107
You need this if you want to implement your own uhdr support, there's a new chapter in the docs for this feature:
https://github.com/libvips/libvips/blob/master/doc/uhdr.md
lua-vips might want to wrap this function.
Note that get_gainmap() does not make a new reference, the caller "borrows" the pointer from the image. You'd probably want to add a g_object_ref() when adding a method to lua-vips. I can make a PR if that'd be helpful.
