WebDec 15, 2024 · They have the same signature, except warpAffine () requires a 2x3 transformation matrix, while warpPerspective () requires a 3x3 transformation matrix. These matrices are computed respectively by the functions getAffineTransform () and getPerspectiveTransform (). The former expects three pairs of matched coordinates, and … One of the main motivations for using matrices to represent linear transformations is that transformations can then be easily composed and inverted. Composition is accomplished by matrix multiplication. Row and column vectors are operated upon by matrices, rows on the left and columns on the right. Since text reads from left to right, column vectors are preferred when transformation matrices are composed:
