Abstract
This report describes the program XV, which is an interactive color image display program for workstations and terminals running the X Window System. The program displays images saved in a variety of popular formats. It lets you arbitrarily stretch or compress the size of the image, rotate the image in 90-degree steps, flip the image around horizontal or vertical axes, crop off unwanted portions of the image, and measure pixel values and coordinates. Modified images can be saved in a variety of formats, or sent to a PostScript printer.
The program also features extensive color manipulation functions, including a colormap editor, hue remapping, brightness and contrast adjustment, and individual mapping functions for the Red, Green, and Blue video channels, to correct for device-dependent non-linear color response.
