Why wouldn't it?
They render ID into rasterized text (blocks of pixels) and blend in these blocks. But they could've just as easily rendered raw 0s and 1s of the ID into blocks the exact same way. It just would've not looked like text, but as a random pattern.
- tjoff 8y agoMaybe I'm not getting what you are saying. But a rasterized text has a lot more information about each character than the raw ASCII values. If you halve the resolution or add compression artifacts an OCR will still pick it up. If they rendered raw binary data they would have to add lots of redundant information as well as spreading it out over a large enough area. Maybe that's what you meant but didn't fit the 'trivially to do' part for me. Seems a lot easier to just render the text.
