Whats new in Touchup 2.3?
To hinder screen copying of images, Touchup can now generate pixel noise. Simply stated, certain pixels of the image are adjusted a small amount to introduce noise throughout the image. This additional detail is difficult for standard JPEG to compress cleanly, so those taking a copy of the image will get a blurry picture. Increase Noise (noiseFrequency) to increase spacing between noise pixels, use the noiseLevel to adjust the strength of the pixel noise. NoiseFrequency of 1 produces a TV scan lines effect, 7 produces vertical lines, and 18 produces a dithered effect. NoiseLevel works just like Brightness, the default of -30 makes the noise pixels slightly darker than the surrounding pixels. Noise pixels can be lined up vertically or staggered, spacing varies from 1-4 lines, horizontal spacing increases as the noiseFrequency is increased. Zoom in to take a closer look at what’s going on. Touchup can now move the image horizontally and vertically to allow cropping. For example, set Hori
