|Developed by||Moving Picture Experts Group (MPEG)||X Window System|
|Type of format||Image Container Format||Image file formats|
|Introduction||High Efficiency Image File Format (HEIF) is a file format for individual images and image sequences. It was developed by the Moving Picture Experts Group (MPEG) and is defined by MPEG-H Part 12. In June 2017, Apple announced support for HEIF in macOS High Sierra and iOS 11.||In the X Window System, the program xwd (X Window dump) captures the content of a screen or of a window and optionally saves it into a file.|
|Technical details||The HEIF specification also defines the means of storing High Efficiency Video Codec (HEVC)-encoded intra images and HEVC-encoded image sequences in which inter prediction is applied in a constrained manner.||xwd runs in one of two ways: if a user specifies the whole screen or the name or identifier of a window as an argument, the program captures the content of the window; otherwise, it changes the shape of the cursor and waits for the user to click in a window, whose content is then captured.|
