Thanks again to everybody,
Your answers helped me to understand better.
My pragmatic solution is now to package my program
with an open source .ttf font,
which will be used on both platforms.

So in the above, from where are the numbers being counted? 10 is ten
pixels from the left border of the image? 20 is twenty pixels from the
