tx and ty are translation. I think a and d are scale and b and c are some function of rotation. I have videos that are flipped and rotated using arbitrary matrices. How can I make them right-side-up ...

Shapes can be transformed in a number of ways. These include translation, rotation and reflection. Translation causes a shape to move. Rotation causes a shape to move. Reflection causes a shape to ...
