Current through Register Vol. 24-06, March 15, 2024

Electronic imaging systems for bitonal images shall use the Consultative Committee on International Telegraphy and Telephony (CCITT) Group 3 or Group 4 compression and decompression techniques without proprietary alterations to the algorithm. For the storage of electronic images of records for which the state or local records committee has approved a retention period of six years or less from the date of creation, a nonproprietary lossless compression algorithm may be used if a utility program or application software option is maintained to convert images to the TIFF Group 3 or Group 4 standard. For the compression and decompression of color images a lossless algorithm, such as TIFF, Group 5, is recommended.
