I have successfully drawn a rectange using
ID2D1HwndRenderTarget::FillRoundedRectangle(), as far as I know, I can do
FillContainsPoint(), but it needs
D2D1_MATRIX_3X2_F. How do I get the
D2D1_MATRIX_3X2_F from a rectangle?
Maybe you can specify NULL for D2D1_MATRIX_3X2_F.
According to ID2D1Geometry::FillContainsPoint,
D2D1_MATRIX_3X2_F is the transform to apply to this geometry prior to testing for containment. You can build up the transform if needed or NULL. See TouchHitTesting Microsoft sample.
Wait, let me try.
