"Intermediate -> PNG" is impossible in principle, because in the Intermediate format all the original image information is lost, only a set of fingerprint features is stored.
"PNG -> Intermediate" requires a call to the DigitalPersona Fingerprint Engine to convert the image into a feature set. The library does not provide access to the engine, but you can get DigitalPersona SDK which allows this.

Such sample is a part of the DigitalPersona SDK, you need to obtain the SDK first.

A fingerprint feature set in a DigitalPersona proprietary format.

I do not understand what do you mean by this? DigitalPersona Fingerprint SDK is a commercial product, which contains a fingerprint engine (a native Windows dynamic library) and distributed by HID Global. If you have purchased the SDK already, then you should have samples of the code with the distributives, as well as contacth of the SDK support team which can help you.

You need to invoke the DigitalPersona Fingerprint Engine functions. You cannot do it in JavaScript, as this is a native API, and it is out of the scope of the @digitalpersona/devices
library.
