| Technical Details | SGI is a generic raster image file format that stores black and white, gray scale and color images. Images in the SGI format are generic bitmap images that have the capacity to store 8 to 32 bits per pixel. The file size of the images can be compressed with the Run-length encoding (RLE) technique. The .sgi extension files begin with a 512 byte header that is fixed and is followed by the pixel data. There is a scan-line table in case of compressed images with the compressed pixel data following the table. The scan-line offset table indicates the start of every scan line in the data of a compressed image. Lots of bit planes, alpha channel data and / or color maps may be included in the files with .sgi extension. Contrary to the top-down order followed by other formats, the pixel data in .sgi extension file follows the bottom-up order. |
