We need a utility to create jpg images with linear gradient fill. We do not want anything fancy. We only need to create rectangles. The utility must be launchable from a batch file with arguments to control the following job options: 1) width (pixels) 2) height (pixels) 3) color depth (32 bit, 24 bit, 16 bit, gray) 4) beginning color (RGB) 5) ending color (RGB) 6) angle (0 - 360 degrees, in increments of 0.1) 7) file name
