Sorry for wrong section (It was like a troubleshooting problem o me).
No, not magnetic Lasso, I was refeing to a tool similar to:
"Plygon Lasso Tool" in Photoshop CS3 or
"Free Hand Selection with Point to Point selection Type" in Paint Shop Pro XI or
"Free Hand Mask Tool" in Corel Photo Paint X3.
A tool to make selections in a unregular polygon mode. Like drawing a polygon but instead you draw the selection area. I think this is a base tool for any graphics software.
For example you have an object, a car for example, and you want to cut off the background or you just want to cut the car and paste it on another image , how do you do this ? How do you select the car?
