Hi Karen.
I must admit we are still using an older version of RB for development that doesn't have the App.UseGDIPlus feature. I have played around with App.UseGDIPlus while testing later RB versions but don't know what happens if used at the same time as the declares.

Hi Karen.
I've just refreshed my memory and the fonts that GDI+ does not support are OpenType fonts based on Postscript (Type 1) outlines (OpenType can either be TrueType or Type1 based). I don't have any font names at hand but you should be able to find some easily. Can't understand why Microsoft supports them in GDI and not GDI+. To use GDI+ via declares isn't as simple as switching it on. It is a completely different API for drawing / measuring etc... so you will need to implement all of the relevant calls. GDI+ is object orientated but there is a flattened API available so Googling that should bring up some useful sites. Standard RB graphics are not effected when using the GDI+ API's. I'm sure Aaron Ballman has implemented some of this in a publicly available project so I would maybe investigate that to help you get started.

Yes.
Microsoft did not finish GDI+. There are certain common font types that GDI will render but GDI+ won't render. We implemented GDI+ directly in our app and we had to swap between RB and GDI+ doing the text drawing depending on the font.
