Could we move all images and other binaries for testing to a new extra repository https://github.com/tesseract-ocr/testing? Keeping the source code repository small saves disk space for all use cases which want to compile the code without running tests. We can still integrate that external repository as a submodule (like it is already done with googletest). @zdenop?

[Shreeshrii]

I think that's a good idea. At the same time, we should also combine some of test related folders Eg. Unittest and Tests Testdata and testing Or Leave the original testing folder as before and add unittest related files to testdata , @stweil would be best, if you can create a PR for @zdenop to merge.

You might want to add at least 2 rotated images and add tests that use them.

@amitdo I have added the rotated images and tests to check that rotation degrees match.

Is there a way to programmatically rotate the images to test, rather than add more images to testdata?

Yes, with Leptonica.
