9 Working with Raster Selection with less color depth into the destination images with a greater color depth: monochrome into grayscale and color, grayscale into color (not into monochrome) color into color only. The names of images that do not fit are excluded from the list of the dialog box. To merge images 1. Select source images (images to be inserted) as AutoCAD images. For example, click on the boundary of each required image. 2. From the rEdit menu, choose Merge. - or - Click the button on the Raster Edit toolbar. 3. If there are several images in the drawing that can be destination images, then the selection dialog box appears. Select destination images from the dialog box (images where source images raster data is supposed to be transferred). Raster data from the source image is added to the destination. The source image disappears. Þ If there are only two images, then the merging will be achieved after the second procedure step. Merging Copy Merging a Copy (i.e. duplication) works in a similar way as merging except it does not erase the source image from the drawing. To perform duplication you perform the same actions as when merging except the command is called Merge a Copy and the button looks like . Transforming Selection Set into Separate Image The detaching operation transforms a selection set into a separate image (or a group of images, if a selection was made on several images) without changing the position or size of raster selection. As described in the section "Changing the status of selected data" a selection set is always transformed into a separate image if its position or size is changed. In some cases it is necessary to transform a selection set into a separate image, without changing the raster selection position or size. For example it is necessary when layering raster images, when the original image is divided into two images of the same size, lying one above another. Such raster layers creation allows separating raster image objects of different types onto separate layers as it is made in AutoCAD for vector objects. For example, you can select all raster texts and 145
