[. . . ] This means that you may specify output dimensions of 5" x 7", but because of intervening variables, the actual output dimensions may be 4. 85" x 6. 9" -- which is the closest the system can produce given your other variables. Aspect Lock is on Input edit boxes are grayed out With Aspect Lock on, only output dimensions can be edited Reference 41 How to use the Aspect Lock The Aspect Lock preserves the ratio of the image width and height from input to output. For instance, if your image is 2 inches wide by 4 inches high, changing it to 1 inch by 2 inches will maintain its aspect ratio. Changing it to, say, 1 inch by 4 inches, however, will alter its aspect ratio, so that the image will be narrower than the original. · If the Aspect Lock is ON: Changing one output edit box (width or height) will automatically change the other output field, as well as scaling, to preserve the aspect ratio. With Aspect Lock on, you cannot edit the input dimensions. Aspect Lock is on Changing one output field will change the other. Note that aspect ratio is preserved (input 2x4; output 4x8); scaling also changed automatically. · If the Aspect Lock is OFF: Changing one input edit box (width or height) will NOT automatically change scaling or the other input field, and aspect ratio can be changed. With Aspect Lock off, you cannot edit the output dimensions. Aspect Lock is off Changing one input field will not automatically change the other. Note aspect ratio is not preserved (input changed from 2x4 in previous box to 3x4). 42 Microtek Scanner User's Guide (PC version) Scaling Scaling is the process of creating larger or smaller images in your scanning software so that you need not resize the images later when they are delivered to your image-editing program. In the scanning software, scaling has an inverse relation to resolution: The lower the resolution, the larger the image can be scaled. To illustrate the use of scaling: Assume that your input dimensions are 4" x 5": · If scaling is at 100%, output dimensions will also be 4" x 5". · If scaling is at 50%, output dimensions will be halved -- to 2" x 2. 5" · If scaling is at 200%, output dimensions will be doubled -- to 8" x 10". The above assumes that your resolution is held constant throughout the changes. When you change resolution and specify a value that has no exact equivalent for scaling, the scaling may be affected and adjusts itself to the nearest allowed value. For instance, if your resolution is 100, your scaling becomes 99 (instead of a full 100), because that is the closest scaling equivalent, given the resolution value. Reference 43 Image Adjustment controls The Image Adjustment controls include the Auto button and the Color Correction button, located below the Image Dimension Controls. Auto (Automatic Contrast Control) The Auto button optimizes the contrast of scanned images by making adjustments to the Shadow/Midtone/Highlight values. The Auto setting works by calculating the image settings of the current scan frame and applying those settings to either lighten or darken an image. Take note of the following: · · If the current scan frame encloses the whole preview image, the Auto setting is applied to the entire image. If the current scan frame encloses only a portion of the preview image, the Auto setting is applied only to the portion of the image within the current scan frame. Experiment with the Auto setting and see how it affects your images. The Auto button will be dimmed if the image type selected in the Type box is "Line Art" or "Halftone". To use the Auto feature: 1 Click on the Preview button to preview the image. 2 3 Click on the Scan Frame tool, and draw a scan frame of the area where Auto will be applied. If you do not like the results obtained by Auto, or if you choose not to use it for certain images that have Auto enabled, click on the Auto button again to deselect the feature. A message will appear, asking if you wish to reset the Shadow / hightlight / midtone values; click Yes. This will return your image to the original. The Auto button 44 Microtek Scanner User's Guide (PC version) Color Correction / DCR This tool applies a generic color correction profile to your images to give it accurate, lifelike color. [. . . ] This saves time, as you don't have to create the settings repeatedly for every scan job you make. Before using Duplicate, it is helpful to turn on the Smoked Glass Background feature. To use the Duplicate button: 1 Click on the Preview button to see a preliminary view of the image. To show the principle of duplication clearly, choose image type (in the Settings window) as Millions of colors. [. . . ]
