Invert Inverts the color values of a color image, or the brightness values of a grayscale image. Apply the filter again to revert the effect. Icon Invert Smooth Softens or blurs the image by applying a low pass filter.low pass filter with a kernel of: 1-2-1, 2-5-2, 1-2-1 Icon Smooth Sharpen Sharpens the image by applying a high pass filter.high pass filter with a kernel of: -1/-1/-1, -1/16/-1, -1/-1/-1 Icon Sharpen Remove Noise Removes noise by applying a median filter.See i70055 Icon Remove Noise Solarization Opens a dialog for defining solarization. Solarization refers to an effect that looks like what can happen when there is too much light during photo development. The colors become partly inverted. Icon Solarization Parameters Specifies the degree and type of solarization. Threshold Value Specifies the degree of brightness, in percent, above which the pixels are to be solarized. Invert Specifies to also invert all pixels. Aging All pixels are set to their gray values, and then the green and blue color channels are reduced by the amount you specify. The red color channel is not changed. Icon Aging Aging Degree Defines the intensity of aging, in percent. At 0% you see the gray values of all pixels. At 100% only the red color channel remains.ufi: cannot see any difference between 0% and 100% aging here... Posterize Opens a dialog to determine the number of poster colors. This effect is based on the reduction of the number of colors. It makes photos look like paintings. Icon Posterize Poster Colors Specifies the number of colors to which the image is to be reduced. Pop Art Converts an image to a pop-art format. Icon Pop Art Charcoal Sketch Displays the image as a charcoal sketch.

Icon Relief Light Source Specifies the light source position. A dot represents the light source. Mosaic Joins small groups of pixels into rectangular areas of the same color. The larger the individual rectangles are, the fewer details the graphic image has. Icon Mosaic Element resolution Determines the number of pixels to be joined into rectangles. Width Defines the width of the individual tiles. Height Defines the height of the individual tiles. Enhance edges Enhances, or sharpens, the edges of the object.
