Hi again, I've been reading carefully and testing what the docs explains from QMatrix class and I don't know how could I use it to obtain the effect that I want . I know that I should call QMatrix::shear and QMatrix::scale in some way because, as the docs says, "...Rotation is achieved by carefully setting both the shearing factors and the scaling factors" but I don't know how
It's clear that I'm not a math expert... Could you please guide me a little bit in how could I configure the QMatrix to get the respective "transformated" rectangle for each angle rotated? Thanks again.
