Detailed Description

Affine 2D image transforms.

Affine transformations allow transformation of images using a transform matrix. The matrix represents the operation to be performed on the image. The transformation matrix is a 3x2 matrix consisting of a 2x2 rotation matrix R combined with a 1x2 translation matrix T.

Matrix Transform = | R | = | r00 r01 | | T | | r10 r11 | | t00 t01 |

The operations that can be represented using this matrix form include rotation, translation, scaling and skew among others.
