javax.media.jai.operator.TransposeType

Class used to represent the acceptable values of the "type" parameter of the "Transpose" operation. Acceptable values for the "type" parameter are defined in the TransposeDescriptor by the constants FLIP_VERTICAL, FLIP_HORIZONTAL, FLIP_DIAGONAL, FLIP_ANTIDIAGONAL, ROTATE_90, ROTATE_180, and ROTATE_270. @since JAI 1.1
