How to get Z-Values?

I need to make a Depth map and get the values from the Z depth channel. I was wondering if there is a way to get those Z values with Python without checking the image that is produced from the Z depth AOV (in 16 bit)? Thanks! (This is for Arnold in Maya)

iff files? Those don't come from Arnold.

You can use OIIO (it has Python bindings) to read the jpg/exr/png/tif output of Arnold.

Exactly. The question is if there is any way to get the Z AOV data within python, instead of storing it as an .iff file, which can be opened only with FCheck. At least, I haven't found any other way to open such files. Moreover, it seems that they support 8-bit values only, but we need at least 16-bit precision.

As far as I know, this isn't possible without rendering the Z AOV.
