So I'm not calling this pixel perfect
You are right. It's not pixel perfect.
The preview is one thing, the final result is another. Not a big problem if the previews is not pixel perfect. But, if I use font size 9 in the designer I want to see font size 9 on the paper. Attached 3 PDFs. With LazReport the fonts bigger than with FreeReport. (Size of three yellow areas are same.) So, the height of memo is okay. LazReport recalculate the height of fonts or what?
