Hi,
What is the best python3 strategy for extracting the data chunk from a small monochrome .png file, representing a QR code? Ultimately, I want to print it serially, pixel line by pixel line, to a dumb serial label printer. I am thinking I need to extract the data field as a matrix to feed to the print routine.
Thoughts / suggestions?
Thanks,
Brian H.
