Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. PIL.Image.Transpose defines enumeration constants for image flips, rotations, and transposition operations.
  2. Image.transpose with FLIP_LEFT_RIGHT and FLIP_TOP_BOTTOM reverses horizontal and vertical axes while preserving dimensions.
  3. Image.transpose with ROTATE_90, ROTATE_180, and ROTATE_270 transforms dimensions and pixel mappings appropriately.
  4. Image.transpose with TRANSPOSE and TRANSVERSE performs primary and anti-diagonal reflection transforms.
