Some links from twitter on the topic of parsing PSD files (haven't looked into them in details). PSD include a flattened rasterized image so this is easy to load if that's the only thing you need. Most software / librairies have support for extracting this flattened data (e.g. stb_image.h does).

However if you want access to individual layers, render non-rasterized layers, emulate every photoshop features, extract or apply effects with more granularity, more code is needed. May range from easy to lots-of-work depending on what exactly you need.

As far as I know there isn't a trivial stb-like ready-to-use C++ library to do that sort of things. Posting all links here. Some are probably bloated or hard to use into your project, some lacking features.

TODO: Actually look into the pros/cons of all those.

"""
Implements tail recursion decorator to overcome Python's recursive limit.

This is similar to my previous, simpler one:

The difference of this version is that it now adds support for stacking up

"""
Implements tail recursion decorator to overcome Python's recursive limit.

This is a simple version that supports single-loop recursion functions like
fibonacci or factorial. There is also a more complex decorator with support 
for branching published here:

Off the top of my head, these are the kinds of things engineering managers often have to deal with:

Hiring:

• Writing job specs.
• Dealing with recruiters
• Reading CVs/résumés
• Interviews
