textract-cli. This is my other OCR project from yesterday: I built the thinnest possible CLI wrapper around Amazon Textract, out of frustration at how hard that tool is to use on an ad-hoc basis.
It only works with JPEGs and PNGs (not PDFs) up to 5MB in size, reflecting limitations in Textract’s synchronous API: it can handle PDFs amazingly well but you have to upload them to an S3 bucket yet and I decided to keep the scope tight for the first version of this tool.
Assuming you’ve configured AWS credentials already, this is all you need to know:
pipx install textract-cli

S3 is files, but not a filesystem (via) Cal Paterson helps some concepts click into place for me: S3 imitates a file system but has a number of critical missing features, the most important of which is the lack of partial updates. Any time you want to modify even a few bytes in a file you have to upload and overwrite the entire thing. Almost every database system is dependent on partial updates to function, which is why there are so few databases that can use S3 directly as a backend storage mechanism. # 10th March 2024, 11:47 am
