Sun Raster Images are bitmaps used as native image format on the Oracle Solaris, the Sun Unix platforms. It was developed by Sun Microsystems, Inc. The format supports storing black & white monochrome, grayscale, and color-bitmapped data of different color depths. It also uses Run-Length data encoding (RLE) for lossless compression.

Interlacing is a method of encoding a bitmap image such that a person who has partially received it sees a degraded copy of the entire image. When communicating over a slow communications link, this is often preferable to seeing a perfectly clear copy of one part of the image, as it helps the viewer decide more quickly whether to abort or continue the transmission.Learn More
