| Format introduction | A camera raw image file contains minimally processed data from the image sensor of either a digital camera, image scanner, or motion picture film scanner. Raw files are named so because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor. | 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 | Raw files contain the information required to produce a viewable image from the camera's sensor data. The structure of raw files often follows a common pattern: a short file header, camera sensor metadata, an image thumbnail and the sensor image data etc, | 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. |
