title: Graphic file compression on a Macintosh.
abstract: AutoDoubler, Compact Pro, DiskDoubler, StuffIt Deluxe, and StuffIt SpaceSaver compression applications for the Macintosh were tested for size of compressed files, and time to compress and expand. EPS, TIFF, PICT and Photoshop native format file types were used, in 1-bit, 8-bit greyscale, 8-bit colour (indexed), 24-bit colour (red, blue, green (RGB)), and 32-bit colour (cyan, magenta, yellow, black (CMYK)) modes. JPEG compression is illustrated by comparing an uncompressed image with three images compressed at different rates.
