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.

Description🔵 .xcf (eXperimental Computing Facility) The .xcf format is the native image file format of the GIMP software (GNU Image Manipulation Program). It's used for storing the entire composition including layers, channels, paths, and other elements that are part of a GIMP imageThe XCF format is designed to preserve all information GIMP can contain about an image; however, due to its specific nature, it's not widely supported outside of GIMP. For sharing, images in XCF format are often exported to more universally recognized formats like PNG or JPEG.
Technical details🔵 The GIF (Graphics Interchange Format), introduced by CompuServe in 1987, is a bitmap image format with these characteristics: - Color Limitation: Supports only 256 colors, making it suitable for graphics or logos but not for detailed photographs. - Animation Support: Stores multiple images for animated effects, popular for looping animations and web graphics. - Lossless Compression: Uses LZW compression, reducing file size without quality loss, effective for uniform color images. - Transparency Support: Allows background transparency in images. - Interlacing Option: Offers an interlaced format for quicker loading on slow connections. - Standardization: Original version (87a) in 1987, enhanced version (GIF89a) in 1989 with animation and transparency improvements. - Aspect Ratio: Lacks inherent aspect ratio support. - Applications: Commonly used online for animation and transparency, less so for high-quality photography due to color limits. - No Audio Support: Cannot embed sound. - Metadata: Limited metadata compared to formats like JPEG. - Browser Support: Broadly supported in web browsers and image viewers. - Patent Issues: LZW compression was patented, leading to controversy and PNG development; patent expired in 2003. - File Extensions: .gif or .GIF. Mainly used for web graphics, animations, and simple art, GIF is efficient for images with fewer colors but not ideal for detailed or high-quality images.
