What about embedded graphics library?

I'm starting a new project where I have to develop a HMI.  I'll use an 
embedded board (Cortex-Mx device) with a relatively small LCD (at least 
2.4", maximum 7").

Any suggestions about an embedded graphics library?  Free or not?

I know emWin that aren't free, but are provided for free by NXP and ST 
as an object library for their parts.

Other suggestions?

Won't that depend on the capabilities that you need/want in that tool?

E.g., doing "static line drawings" takes a lot less resources/effort than
full motion animations, etc.

Google "PEG" (Portable Embedded Graphics).  I've never used it, and it's 
been nearly 20 years since I had to nod politely at the happy raving from 
the neighboring cubicles about how nice, compact and portable it was.

But when I mention it here I think the news is that it's still around and 
still good.  It's not free, but unless someone's really messed it up it 
should be worthwhile.

I've been happy with the Ramtex libraries.

I am really happy with emWin. It does the job, even using the indirect
interface mode.
Easy to write your own touch driver if you need better filtering and
linearisation.
For me it was free since I used an NXP based device (micro Touch 2.8" -
UT28090621EU).
