Feature request: validate TLM marker #183

Closed boxerab closed 2 years ago

boxerab commented 2 years ago

It should be possible to parse TLM marker and validate if all tile lengths are included. Here is an example of an image with a corrupt TLM marker:

also, here is some code that parses a TLM marker

Thanks, both the image and the code look really useful. TLM validation is already on the wish list as per issue 29, so I've added a comment there with your links.
