pingo is a context-based optimizer (IIRC ~ 2017 and even more with ax versions): it would do identification of image data. that is done regardless of what was asked (lossless, lossy, transforms, etc). if the heuristic works as intended, it would have a precise idea (a profile
) of what should be best for the image regarding speed/result
analyse & trials
pingo would be adaptative to preserve speed all along the process: unlike the classical approches to test everything and see
— which is probably the most efficient regarding filesize — it could set a minimal amount of trials (or none) according to the etablished profile, the compression level, the image definition, structure, etc.
