An OCR engine found text anywhere on a PDF page. A separate parser could tell me whether a rectangle on that page contained text, an image, both, or neither. Given a piece of OCR output, I needed to decide whether it came from a text layer or from pixels that merely looked like text. When neither answer was reliable, the system would say “unknown”.</p> <p>The problem was easy to state, easy to understand and easy to test. So why did it take me hours?</p>
