Selecting with the magnetic lasso
You can use the magnetic lasso tool to make freehand selections of areas with high contrast edges.
When you draw with the magnetic lasso, the border automatically snaps to the edge you are tracing.
You can also control the direction of the tool’s path by clicking the mouse to place occasional
fastening points in the selection border.
You’ll now make an ear for the melon face by using the magnetic lasso to select the red part of the
grapefruit slice.
1
Select the zoom tool, and click the grapefruit slice to zoom in to a 200% view.
2
Hold down the mouse button on the lasso tool in the toolbox, and drag to the magnetic lasso tool
( ) to select it.

Now click once at the lower left corner of the red flesh of the grapefruit slice, release the mouse
button, and begin tracing the outline of the flesh by dragging to the right over the curved upper
edge. Notice that the tool snaps to the edge and automatically puts in fastening points.
If you think the tool is not following the edge closely enough (in low contrast areas), you can place
your own fastening point in the border by clicking the mouse button. You can add as many fastening
points as you feel necessary. You can also remove fastening points and back up in the path by
pressing the Delete key and moving the mouse back to the last remaining fastening point.

When you reach the lower right corner of the grapefruit flesh, double-click the mouse button,
which signals the magnetic lasso tool to return to the starting point and close the selection. Notic
