macOS How is organized Quicktime's "covr" atom ?

[jeanmilost]

Hi everybody

I'm currently developing a c++ program to read/write into quicktime files. Now it's time to create code to read/write attached pictures (covr) atom.

I've understanding the main structure of the covr atom, whitch can contains one or many data subatoms, that represents an array of pictures. But I can't find documents about how pictures are sorted into covr atom. Contrary as MP3 structure, pictures subatoms seems not contains informations about pictures details (front cover, back cover, ...)

So, anybody can give informations or interesting links about how picture are organized into quicktime cover atoms ?

Regards

Ok, I think that's not sorting definition and type informations into cover's pictures. I will implement my function differently. Thanks you for answers
