Public Methods

Method	Description
Combine ( Transform transform ) : void	Combine the current transform with another one. The result is a transform that is equivalent to applying this followed by transform. Mathematically, it is equivalent to a matrix multiplication.
GetInverse ( ) : Transform	Return the inverse of the transform. If the inverse cannot be computed, an identity transform is returned.
Rotate ( float angle ) : void	Combine the current transform with a rotation.
Rotate ( float angle, Vector2f center ) : void	Combine the current transform with a rotation. The center of rotation is provided for convenience as a second argument, so that you can build rotations around arbitrary points more easily (and efficiently) than the usual Translate(-center); Rotate(angle); Translate(center).
Rotate ( float angle, float centerX, float centerY ) : void	Combine the current transform with a rotation. The center of rotation is provided for convenience as a second argument, so that you can build rotations around arbitrary points more easily (and efficiently) than the usual Translate(-center); Rotate(angle); Translate(center).
Scale ( Vector2f factors ) : void	Combine the current transform with a scaling.
Scale ( Vector2f factors, Vector2f center ) : void	Combine the current transform with a scaling. The center of scaling is provided for convenience as a second argument, so that you can build scaling around arbitrary points more easily (and efficiently) than the usual Translate(-center); Scale(factors); Translate(center).
Scale ( float scaleX, float scaleY ) : void	Combine the current transform with a scaling.
Scale ( float scaleX, float scaleY, float centerX, float centerY ) : void	Combine the current transform with a scaling. The center of scaling is provided for convenience as a second argument, so that you can build scaling around arbitrary points more easily (and efficiently) than the usual Translate(-center); Scale(factors); Translate(center).
ToString ( ) : string	Provide a string describing the object
Transform ( float a00, float a01, float a02, float a10, float a11, float a12, float a20, float a21, float a22 ) : System.Runtime.InteropServices	Construct a transform from a 3x3 matrix
TransformPoint ( Vector2f point ) : Vector2f	Transform a 2D point.
TransformPoint ( float x, float y ) : Vector2f	Transform a 2D point.
TransformRect ( FloatRect rectangle ) : FloatRect	Transform a rectangle. Since SFML doesn't provide support for oriented rectangles, the result of this function is always an axis-aligned rectangle. Which means that if the transform contains a rotation, the bounding rectangle of the transformed rectangle is returned.
Translate ( Vector2f offset ) : void	Combine the current transform with a translation.
Translate ( float x, float y ) : void	Combine the current transform with a translation.
operator ( ) : Transform	Overload of binary operator * to combine two transforms. This call is equivalent to calling new Transform(left).Combine(right).
operator ( ) : Vector2f	Overload of binary operator * to transform a point. This call is equivalent to calling left.TransformPoint(right).
