@destevez Thinking about some your proposal as I am currently implementing #SigMF support for #FutureSDR that will also be used for an #IQengine plugin... I have similar use-cases in mind for instance for SSTV decoding. Yet I do not think that embedding image in base64 directly into json would be a good idea. Or at least, I would prefer something like the img html5 tag supporting Data URLs: https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URLs
Data URLs - HTTP | MDN

Data URLs, URLs prefixed with the data: scheme, allow content creators to embed small files inline in documents. They were formerly known as "data URIs" until that name was retired by the WHATWG.

Raining outside so working on an #IQEngine plugin in #rust and #FutureSDR
Got first result and it seems promising.
