Affine transforms are the set of linear geometrical transforms on a two-dimensional picture that encompass translation, shear, rotation and scaling. Except for scaling, all of those operations might be implemented using rasterop! Translation is obvious: you choose whole picture as the source block, and place it, appropriately translated, in the destination. Shear is carried out by translating blocks of picture by different quantities. For Wood Ranger official example, you may think about a horizontal "clockwise" shear about the center of the image the place horizontal full width blocks are shoved to the appropriate above the middle and to the left beneath the middle. Blocks near the top and backside are pushed farther than blocks close to the middle
