@nprofile1q... Hypothetically, if someone were to extract all the brush strokes from a file, wrote them into a book, retyped that book back into a file and re-rendered them to claim that it's original work, to me that's still a clear-cut infringement, not even de minimis (which could apply if only e.g. less than 0.1% of the brush strokes were used).

At the end of the day, copyright is an economical tool to ensure the author is fairly rewarded for their work, not an obfuscation challenge.
