Thank you very much for the explaination Paul!

yeah... i've been working with many graphics APIs for over 10 years, and i have to admit this one is the first to be problematic. i have tried to explain that to the private API developers (A2iA checks recognition software), i'll see what they'll answer.

Thank you very much for your time guys!
Best,
