write_exr()
The EXR file specification requires particular types to define the metadata for the image. This function helps define these metadata attributes.
exr_attrs(
channels = NULL,
compression = NULL,
dataWindow = NULL,
displayWindow = NULL,
lineOrder = NULL,
pixelAspectRatio = NULL,
screenWindowCenter = NULL,
screenWindowWidth = NULL,
...
)

In the majority of cases for basic image output, there is no need to specify
anything with this function. write_exr()
will create mandatory
attributes required for image output.
Note that all values must be an object with class exr_type
. To
create these types, use exr_type$<TYPE>(...)
.
