Description.sun The .sun file format is associated with Sun raster files, which are a raster graphics file format originally used on SunOS by Sun Microsystems. It's a bitmapped format, which means it contains a bitmap of the image. However, this format is not commonly used anymore and has been largely replaced by more modern and efficient image formats like PNG and JPEG.
Technical detailsThe `.sun` file extension, associated with the Sun Raster image format developed by Sun Microsystems, is not as widely recognized as standard formats like .jpg or .png. This raster image format, used mainly on Sun's Unix-based systems, is designed for pixel-based images, supporting various color depths like 1-bit (black and white), 8-bit (gray-scale or indexed color), and 24-bit (true color). It offers simple RLE (Run-Length Encoding) compression but can also store uncompressed image data. The file structure includes a header detailing image dimensions and bit depth, followed by the image data. Its use was mainly within Sun Microsystems environments, leading to limited adoption and support in modern software. Now considered a legacy format, Sun Raster files often require conversion to more common formats for use today. The format is of historical interest, reflecting its specific role in Sun Microsystems' ecosystem rather than as a widely accepted standard.
