Detailed Description

2D transform composed of scale, rotation, and translation.

Convenience class that decomposes a 2D affine transformation into its constituent components and can produce a Matrix2x3.

Constructor & Destructor Documentation

Transform()

AeonGUI::Transform::Transform	(	const Vector2 &	aScale,
		float	aRotation,
		const Vector2	aTranslation )

Construct from scale, rotation, and translation.

Parameters
