10 Creating raster objects Click the PixelDraw button on the WiseImage toolbar. From the rEdit menu choose PixelDraw. - or Start the operation without selecting an image. Select an image you want to process using the dialog box. If you edit a monochrome image, then the following prompt appears: eXit/Undo/Width/Draw/Erase/dOts/Lines/Polylines/Freehand If you want to modify a line width, then choose the Width option and enter a new line width in AutoCAD units or measure it on screen, specifying two points. The following options define the type of the created object: dOts - a filled circle with a diameter of a specified width (default option); specify circle centers in the image to create; Lines - a linear object of a specified width; specify its start and endpoints to create; Polylines - an open polygon made of linear segments, specify the vertices to create and right-click or press ENTER to complete; Freehand - an arbitrary curve; specify the first point to create and move the cursor, drawing the required curve, for completion - click on the end point; The Draw and Erase options define the drawing color: the Draw option sets the foreground color, and the Erase option sets the background color; in the second case the raster objects under the created object are erased; The eXit option completes the command; the Undo option cancels the latest step on pixel editing without interrupting the procedure. If you edit either a color or grayscale image, then the following prompt appears: eXit/Undo/Width/Color/pIck/dOts/Lines/Polylines/Freehand This prompt contains two more options than the previous one (but lacks Draw and Erase): Color - allows selecting a drawing color from the dialog box; pick - to select a drawing color in the image, point to a color sample in the image with the cursor. The rest of the options are the same as described above. Floodfilling and erasing with floodfilling Using the floodfilling operation you can fill raster areas within closed outlines with raster object color (foreground) and erase isolated raster objects - fill them with the raster background color. 155
