Picture data usage

[HipyCas]

I am trying yo use this library to parse the data from some files, and everything works perfectly fine expect the cover data. I cannot get to understant what data it is passing to me, as it is neither divisible by 3 nor 4. ¿Any idea on how to get the pixels from the array?

(My current objective is to render it in JS using a canvas, which needs an array of RGBA values)

Tags embed the full image file, if you need it decoded you should check out the image crate.
