i remember an old X application called "xv" that has lacked maintenance for ages and has since disappeared, probably due to being incompatible with today's graphic library APIs. does anyone remember using this? i'm looking for something that can do like things in the simple way it allowed.
it would alter the coloration of individual pixels in various useful ways, all pixels at once. it could change brightness, contrast, gamma of an image in all colors at once or in any individual primary color. it could shift the hue 360 degrees around a circle to anywhere you want. it could map any brightness level to any other using an N-point curve you could draw. it could do all these things with elegant tools all in a single window. so there were minimal windows (one for the image, one for the controls).
