Capturing <canvas> pixels via Selenium / Python

Question

I do automation on the side. I would like to somehow interact with the HTML page through Python code and access the pixel data. What options does Selenium offer for its approaches?

Possible considerations

• Access raw pixel data in working memory

• Get pixels by saving them in a local image file (PNG)

• Get the pixels by storing them in memory, listening to the port on the local host and pushing the AJAX data there

• Creating an image file and accessing it directly in working memory
