XWD vs JP2:
|Full name||X Windows System Window Dump||JPEG 2000|
|File extension||.xwd||.jp2, .j2k, .jpf, .jpx, .jpm, .mj2|
|Developed by||X Window System||Joint Photographic Experts Group|
|Type of format||Image file formats||Graphics file format|
|Introduction||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.||JPEG 2000 (JP2) is an image compression standard and coding system. It was created by the Joint Photographic Experts Group committee in 2000 with the intention of superseding their original discrete cosine transform-based JPEG standard with a newly designed, wavelet-based method.|
|Technical details||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.||JPEG 2000 code streams are regions of interest that offer several mechanisms to support spatial random access or region of interest access at varying degrees of granularity. It is possible to store different parts of the same picture using different quality.|
