Convert sfw to xwd

What is the difference between .sfw and .xwd?

Description: The SFW file format is associated with Seattle FilmWorks, a photography and film processing company. It was primarily used for images that were developed and digitized by Seattle FilmWorks. The format was proprietary, meaning it required specific software provided by Seattle FilmWorks or compatible third-party applications to view or convert the images. SFW files were popular in the late 1990s and early 2000s, especially among consumers who used Seattle FilmWorks' mail-order film developing service.; The XWD (X Windows Dump) image file format is a native graphic format associated with the X Window System, which is a windowing system for bitmap displays commonly used in UNIX and Linux environments. An XWD file is essentially a dump or snapshot of what is being displayed on a screen or part of it at a given moment. It stores image data in an uncompressed form, including the header information that contains details about the image's size, color, and format.
