To mirror an image: Click the Mirror command in the Image box. Invert The Invert function enables you to make a positive view of a scanned image negative or to make a negative image positive. By applying this command, the brightness value of each pixel will change to an inverse value on 256-color scale. To invert an image: Click the Invert command from the Image box after applying the Prescan function. 10 Descreen Descreen filter is used to eliminate the moire patterns (wavelike lines) from the images. As the images are scanned directly from screen-print media (like newspapers or magazines), you should notice that the scanned images usually come with wavelike patterns and banding lines. As long as the scanning resolution is not set very high, you can apply this function to remove those annoying effects. (When this function is activated, the scanning speed will become slow. ) Click on the descreen icon, and a dialog box titled "Descreen" will appear. There are three items in the top dialog box: Normal Scan, Default Setting and Customize. Select "Normal" then descreen will not perform onto the scanned images. Select "Default" to perform the default setting of various document types. In addition, select "Customize" to define your own descreen level by entering a desired value in the number box. Gamma Sometimes you wish to adjust the brightness of midtones of the scanned image while keeping shadow and highlight areas relatively unchanged. The Gamma correction function allows you to increase or decrease the intensity of the middle gray tones. The available gamma value ranges from 0. 01 to 7. 99. Changing the gamma value above 1. 0 will brighten the midtones, while below 1. 0 will darken the midtones. You can either enter the desired gamma value in the edit box or use the scroll bar to select your desired value. 11 In the "Channel" checking box: All To correct all color components (red, green, and blue) of the image with the same gamma value.
