Had a look into the library to improve performance of data transfer for puzzle and chatbox readers in Clue Trainer, and came across this section, which has some potential in my opinion.
byte-base64)Buffer.from(str, "base64")alternative is slowe by a huge factor.Profiling on my device results in speedups of around 30%, both for smaller areas (slider puzzles) and full screen captures.
This only covers the path via
ImgRefBind.read. I haven't touched other usages ofdecodeImageStringyet, but they are probably worth looking at as well.There's also the question of
maxtransfer. Why is the value inwrapper.ts(40000) different from the one that is provided at runtime atalt1.maxtransfer(100000)? Which one is right? Could performance be improved by using the larger one?
