Unfortunately that's not possible. Each library makes choices and tradeoffs on their defaults. Each time, I set whatever quality dials existed to the highest available, and I standardized on 75 JPEG compression. There is no way to get consistent quality across all libraries, which is why I included the results for the 12 images used in the test in the blog post, so everyone can handle this the way they want.
