Cheers Abigail, that works fine. I surprised myself, I was a lot
closer than I thought! :)

getData returns an opaque pointer that you can then fetch to
getPropertyDouble. Try something along the lines of
MetaData::Bundle::PropertyPtr property = _bundle.getData("exr/blah");
double values[16];
for (int i = 0; i < 16; i++) {
values[i] = MetaData::getPropertyDouble(property, i);
}

Hi,
I'm able to return a value from an EXR's metadata using getDouble() but
I'm struggling to understand the syntax to return an array of numbers.
I want to extract the camera matrix as an array of 16 doubles and I
presume getData() is the way to go but I'm not having much luck as I'm
not quite sure what this returns.
My alternative method is to return the matrix as a comma-delimited
std:string of values but I get the impression that this is just created
from an original array? Seems the long way around.
Cheers,
Steve
