| Description | The SFW format is a raster graphics format used for storing bitmap images. It was developed by Seattle FilmWorks and is used mainly for storing photographs. The SFW format uses lossless compression and supports 24-bit color depth. |
| Technical details | The SFW file format is a proprietary format, and the specification is not publicly available. The format is based on the RLE (Run-Length Encoding) compression algorithm, which compresses the image by encoding runs of identical pixels into a shorter representation. The SFW file consists of a header and the compressed image data. The header contains information such as the image size, resolution, and color depth. The compressed image data is stored in a sequential order, row by row. |
