Translate a point by a displacement vector (dx, dy) and return the image coordinates.
Translation shifts every point by the same displacement vector (dx, dy). The image point is (x+dx, y+dy). Translation preserves shape, size, and orientation.
Translation
(x', y') = (x + dx, y + dy)
No — translation is a rigid motion. It moves all points the same distance in the same direction without rotating or resizing.
Apply the opposite vector: (−dx, −dy).
