Maruan Sahyoun commented on PDFBOX-6151:
----------------------------------------
I've added {{SlidingBitmapWindow}} together with the unit tests and a JMH
benchmark as I think this is useful for debugging and comparison purposes. As
can be seen in PDFBOX-6199 it's correct i.e. all tests pass but compared to a
pixel-by-pixel it's still slower because of all the function calling overhead.
The inline sliding bitmap code is the fastest but difficult to test for
correctness. {{SlidingBitmapWindow}} can serve as a testable boilerplate
whenever we'd like to look at the performance gains at the cost of readable
code.
