WiseImage - User's Guide The program defines the Max Width value equal to the length of the part of the line that crosses the raster line. To measure Max Break on an image 1. Click the button next to the Max Break box. 2. Specify two points in the raster image, so that the line connecting these points crosses the largest gap in the raster line. The program defines the Max Break value equal to the length of the part of the line that covers the raster background. Raster Snap Modes The raster snap modes implemented in WiseImage are the same as AutoCAD's object snap modes and work in the same way. This table provides the names of raster snap modes, which can be used to snap to points of raster objects. Name Endpoint Description Snap to the raster objects endpoints (lines, arcs etc.). Midpoint Snap to the middle of raster objects (lines, arcs etc.). Center Snap to the center of a raster arc, circle. Quadrant Nearest Intersection Perpendicular Tangent Snap to the nearest quadrant (the point located under an angle 0, 90, 180 or 270 degrees from center) of arc, circle. Snap to the point of the raster object located closely to the indication point. Snap to the intersections of raster objects (lines, circles, arcs etc.). Snap to the point of the raster object lying perpendicular to another object or to its imaginary extension. Snap to the point on an arc or circle belonging to the tangent of another object. Raster Snap on Demand To snap to a specific point of a raster object, the raster snap cursor menu is used. To open the raster snap cursor menu, right-click with the CTRL pressed. To snap to the characteristic point of a raster object 1. During the execution of any object construction command, in reply to the point input prompt, select the object snap mode from the cursor menu or rImage > Snap menu. 2. Move the cursor to a position close to the required snap point and click. You will see a highlight marker and tooltips. 166
