What do you mean by points? The standard image classes just have one point, with an (x, y) location. Please be more specific.

I'm thinking the original poster wants to define a polygon, and create a new image that is the intersection of the original image and the polygon.

Take a look at the Graphics class. You can get an instance of it from an instance of Image.
