Drawing in WINAPI WCE800 with antialiasing

Can antialiasing be enabled somehow when using WINAPI in WCE800?

But I forgot to write that I am using C++ with WINAPI.
And in your links, I did not find an example of using antialiasing ( for example, drawing a line) in C++ with WEC800. Could you give me such an example?

The Windows Mobile Ink an DirectX is a part of WINAPI and they are support antialiasing. If you are talking about GDI API only - I’m afraid that there is no support for antialiasing. Anyway it’s completely OEM independent and has nothing specific to Toradex HW. Please check an MSDN or Microsoft community for details related to antialiasing.
