Hi again!
Is it possible somehow to draw atlas part rotated with specific angle just like Image::drawRotate(..)?

Hi,

Yes but you'll have to manually specify vertex positions / tex coords

You can use the following function for that:
static void face(C Vtx2DTex &a, C Vtx2DTex &b, C Vtx2DTex &c, C Vtx2DTex &d);
VI.face(..);

Thanks, VI turned out to be quite useful for 2D.
I'm not sure but it even seems to draw faster than image->draw(..)

VI will be faster if you make calls batched together, that's the whole point of it.
Vertex/Index buffering for faster performance.

This time I need to draw atlas part rotating and fading out with transparency in the same time. Problem is that VI.face does not respond to VI.color.
How can I do it then?

You can use:
and specify color per-vertex
