First, we understand that some machine learning examples are hard-coded to handle only jpg or png, but converting the original data to an 8 bit format truncates the dynamic range and is probably a bad idea.

That out of the way, you can use the [ScreenCapture](https://slicer.readthedocs.io/en/latest/user_guide/modules/screencapture.html) module’s slice sweep mode to catpure the images. [Here’s an example](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#capture-a-slice-view-sweep-into-a-series-of-png-files) doing this from a python script.

The [batch processing](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#batch-processing) examples will get you started applying this to a set of images.
