type 3 font - baseline

When using embedded type 3 font, text is always written a few pixels lower than when using embedded true type font. The problem is worth as the font size increase, to the point that it could overwrite part of the next line (if text on that line use a smaller font).

Is it a known problem when using embedded type 3 font or is it a bug related, maybe, to baseline configuration in such fonts ?

In my test case, the only difference is the option FontMode set to wpEmbedTrueTypeFonts or wpEmbedType3. I have some pdfs generated with the two options.

I finally found something to show you the images :

With embedded TrueType fonts :

Thanks for the hints.

I have downloaded the latest version (4.71 / 16.02.2019). There is a huge improvement for horizontal text with type 3 fonts. It is probably good enough for our use case. But there is also a huge regression for vertical text (we were still using 4.33).

Here is the rendering on screen :

And here is the PDF rendering with the latest version :

This problem is not limited to type 3 fonts. Embedded True Type fonts has the same problem. I have not yet tested other parameters.

Is there any plan to fix the vertical text positioning problem ?
