Transforms

Silverlight provides a powerful set of transforms to apply to the visual object. The following is a full set of 2D transforms:

• TranslateTransform: This shifts an object in a 2D plane.

• ScaleTransform: This scales (or resizes) the object by the ScaleX factor along the X-axis and the ScaleY factor along the Y-axis.

• SkewTransform: Skewing along the X-axis turns every vector orthogonal to the X-axis by the same angle defined by AngleX, and expands its length so that its Y coordinate stays the same. The AngleY parameter of the transform is in charge of skewing along the Y-axis.

• RotateTransform: This rotates an object by the Angle parameter.

• MatrixTransform: This is a generic transform that can represent any linear transformation and translation within a 2D plane.

We previously used RotateTransform to rotate the rectangle.

There is also the PlaneProjection transform imitating the moving of an object in a 3D space. We will describe this transform in detail later in the book.
