Sgi is a lossless image format. It can be uncompressed or use an RLE variant. The first 16bits of the file format should be the big-endian value 0x01da to be identified as a valid sgi image. It supports the following pixel formats: (ffmpeg notation in brackets)
- 8 bit grayscale. (PIX_FMT_GRAY8)
- 24 bit, 1 byte for each of R,G, and B. (PIX_FMT_RGB24)
- 32 bit, RGB + one byte for the alpha-channel. (PIX_FMT_RGBA)
