Yes this one does not have scaling because I was just doing an example to check proportionality.
So what I understand is to be consistent across different canvases where pixels/mm are different I should internally store the size of text I display in pixels? That way when I implement scaling it would be on pixels and remain consistent. But when I tried to convert the pt size to pixels I am not having good results. For example to convert 12 pts to pixels I did this: cd.MM2Pixel(12/cd.MM2PT, 12/cd.MM2PT ) But this returns 0. How do I translate this?
