I'm trying to use png image with emWin, but I have compilation problem the IMAGE_SetPNG is not defined.
I use the emwin_png.zip for emwin518.
Somebody has already tried this?

Thanks

Hi,

That's right, the current libraries do not have PNG support due to some issues with the PNG library. We are looking into this and plan to release new libraries with PNG support soon.

Thank you for your reply.
Where come from the problem emwin or the PNG library?
Is exist a version where the emwin work with PNG?

So how do I get PNG to work.
I downloaded the latest version of the emWin with PNG support in the graphics library.
I copied the contents of emwin_png.zip to emWin directory where the emWin_Config, header and library are.

I still get
undefined reference to `GUI_PNG_Draw'

I included it in the library path in the project right under the support for emWin.

Whats the trick to get it to work?
