Flash glossary: Lasso tool
The Lasso tool in Adobe Flash Professional enables you to select objects on the Stage by encircling them with a marquee. There are two options when using the Lasso tool: freehand (the default setting), Polygon Mode, and Magic Wand.
Using the Lasso tool with the Magic Wand modifier, you can select areas of a bitmap graphic that contain the same or similar colors. Click the Magic Wand settings to specify the Threshold and Smoothing values. Experiment with different settings to choose the selection options that work best with the bitmap content you want to select.
To select objects by drawing a freehand selection area, follow these steps:
- Select the Lasso tool in the Toolbar panel. Drag the Lasso tool around the area.
- End the loop approximately where you started or let Flash automatically close the loop with a straight line.
To select objects by drawing a straight-edged selection area, follow these steps:
- Select the Lasso tool's Polygon Mode modifier in the options area of the Tools panel.
- Click to set the starting point.
- Position the pointer where you want the first line to end and click. Continue setting end points for additional line segments.
- Double-click to close the selection area.
To select objects using both freehand and straight-line edges, follow these steps:
- Deselect the Polygon Mode modifier of the Lasso tool.
- To draw a freehand segment, drag the Lasso tool on the Stage.
- To draw straight-edged segments, hold down the Alt key (Windows) or Option key (Mac OS) and click to set start and end points for each new line segment.
- To close the selection area, do one of the following:
- Release the mouse button; Flash will close the selection area for you
- Double-click the starting end of the selection area line
Note: Using the Lasso tool and its Polygon Mode modifier, you can switch back and forth between the freehand and straight-edged selection modes.
To learn more about working with the Lasso tool, see the section titled Selecting objects in the Flash documentation.
