- Description
- The X11 file type, associated with the X Windows System, is a format designed to contain screen or window dumps (screenshots) from the X Window System, a windowing system for bitmap displays common on UNIX-like operating systems. These dumps are essentially captures of the graphical output of applications running within the X environment, saved in a format that can be viewed or analyzed later. The X Window System serves as the foundational graphical interface for many Linux and UNIX systems, facilitating a wide range of graphical applications. X11 files enable users to save and share the state of a graphical interface at a specific point in time, useful for documentation, debugging, or graphic design purposes.
- Based on HEVC (High-Efficiency Video Coding), the HEIF format is an image file container with one or multiple images and is the default image format for Apple Live Photos. It replaced the JPEG format as it's smaller in size and has lossless compression ensuring high-quality photos.
