Information about SFW and GIF file formats

🔸 File format SFW GIF
🔸 Full name SFW, Seattle FilmWorks image GIF - CompuServe Graphics Interchange Format
🔸 File extension .sfw .gif
🔸 MIME type application/octet-stream image/gif
🔸 Developed by Seattle Filmworks CompuServe
🔸 Type of format Raster image lossless bitmap image format
🔸 Description Bitmap images with an SFW file extension have been created with the, by now, outdated application Seattle FilmWorks which was used for film processing. Some programs can still view SFW files even though files with this extension use a proprietary format. Seattle FilmWorks and PhotoWorks have been discontinued. The Graphics Interchange Format (better known by its acronym GIF) is a bitmap image format introduced by CompuServe in 1987. It has since come into widespread usage on the World Wide Web due to its wide support and portability.
🔸 Technical details The SFW file format is an MGI PhotoSuite file and a raster image file. This file extension is also captured by IrfanView, Graphics Converter Pro, and others. GIF supports up to 8 bits per pixel for each image, allowing a single image to reference its palette of up to 256 different colors chosen from the 24-bit RGB color space. In addition, GIF images are compressed using the Lempel-Ziv-Welch (LZW) lossless data compression technique to reduce the file size without degrading the visual quality.
