The spatial data structure known as bincode is a simple and storage-saving encoding scheme for representing binary images. In this paper, we first present eight efficient operations for mirroring and rotating bincode-based images. Among the operations, certain special operations on individual bits within bincodes are needed. Then we present a newly proposed logical representation for implementing the bitwise operations in the operations. Finally, we implement the bitwise operations in hardware to speed up the special manipulations.
