From looking at the various manuals its obvious that PNG and truetype font support are not included in the emWin distribution.
The manual says in both cases to download the package and install it.

So what does that mean in an LPC Open world?
Maybe someone that knows could explain what install it would do.
What directory does it go into.
What paths have to be change to get it to compile in?

Can say but one thing.

True type fonts are rendered on the fly from digital data.
You would have to cache the rendered bit maps of suffer the penalty of re-rendering each glyph.
Such a thing would likely drag your performance to it's knees since it is all done in floating point.
just saying.

I think I understand the pain of using the truetype driver.
However I can't get it to compile in to try it.
My use of the fonts is generate them and then use them later. Got lots of RAM laying around.
It will use a lot of RAM but dragging megabytes of font files of different sizes off the flash drive isn't very fast either.
Trying to find some middle ground.

Do you know how to get it to install with the latest LPCopen?
