□ Encoding and decoding in open-source WEBM video format are possible while using the ffvp8 software or libvpx from the Google support. By using the HTML5 version of YouTube, one can watch videos encoded in WEBM. It is a freeware offering streaming of online video content. □ Like the MKV file extension, the WEBM royalty-free extension is developed by various online parties such as Google. 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. Patent Issues: LZW compression was patented, leading to controversy and PNG development patent expired in 2003. Browser Support: Broadly supported in web browsers and image viewers. Metadata: Limited metadata compared to formats like JPEG. Applications: Commonly used online for animation and transparency, less so for high-quality photography due to color limits. Aspect Ratio: Lacks inherent aspect ratio support. Standardization: Original version (87a) in 1987, enhanced version (GIF89a) in 1989 with animation and transparency improvements. Interlacing Option: Offers an interlaced format for quicker loading on slow connections. Transparency Support: Allows background transparency in images. Lossless Compression: Uses LZW compression, reducing file size without quality loss, effective for uniform color images. Animation Support: Stores multiple images for animated effects, popular for looping animations and web graphics. Color Limitation: Supports only 256 colors, making it suitable for graphics or logos but not for detailed photographs. □ The GIF (Graphics Interchange Format), introduced by CompuServe in 1987, is a bitmap image format with these characteristics: For sharing, images in XCF format are often exported to more universally recognized formats like PNG or JPEG. 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. xcf format is the native image file format of the GIMP software (GNU Image Manipulation Program). □ Microsoft Windows Photo Gallery Viewer
