## Description

python-qrcode is a library for generating QR codes from data and exporting them as images, vectors, or terminal text. It provides specialized encoders for producing portable network graphics, scalable vector graphics, and ASCII text representations.

The project supports visual styling and custom branding, allowing for the modification of module shapes, the application of custom colors, and the embedding of logos.

The capability surface includes image file export for digital assets and terminal-based visualization for displaying QR codes directly within a command line interface. It also manages digital image manipulation and format management to support various visual transformations.
