9 Working with Raster Selection - or - Use the button on the WiseImage toolbar (Merge a Copy command from the rEdit menu) to insert a copy of the transformed data. Thus, you can insert several copies of modified data into one or several images. Duplicating Parts of an Image Since raster selection set is an AutoCAD object, you can copy it using the commands COPY, ARRAY, as well as copy using dragging and the CTRL key. Raster selection copies become separate raster images. During this operation the automatic cropping of obtained raster images by the raster data boundary can be made (by the raster selection of clipping boundary). * Control on copying operations is performed in the WiseImage tab of the dialog box of the AutoCAD options dialog, as described on page 38. Raster images, obtained after copying, are independent from the raster selection set. This means that separate storage areas are created for these copies where the raster data is stored, which allows manipulating the raster data of each copy independently. Thus, when a new copy is created, the extra storage area can considerably reduce the system performance. For example, when the ARRAY command runs, several copies are created, and for each copy by default a separate raster data copy is created. Obviously, in this case the most convenient way is to create a separate raster storage area for all raster selection copies obtained. The current copying mode defines if it is necessary to create either separate storage areas or a single united one. * Control the copying mode of raster layer is performed in the WiseImage tab in the dialog box of the AutoCAD options dialog, as described on page 37. To duplicate an image part 1. Select the raster data. 2. Specify a boundary of the raster selection to select it as an AutoCAD object. 3. Using the AutoCAD tools, create the required number of raster image copies. 4. Insert the obtained images in other images using the merging operation. If you do not insert the obtained copies in the existing images, then you have to save these copies to separate raster files when you finish working with WiseImage. Example: Deskew part of an image The following example shows how to deskew a part of an image using the WiseImage and AutoCAD tools. For this purpose you can use the WiseImage selection tools and the AutoCAD command ROTATE. In this example we use the 147
