Phạt cảnh cáo Khi bạn làm việc với các điểm neo trong công cụ Magnetic Lasso, hãy nhớ rằng các công cụ chính nó vẫn còn mang theo một đường lựa chọn đó để lại một thức của neo không có vấn đề mà bạn mất nó. Nếu bạn không cẩn thận, bạn sẽ tạo ra một gợi nhớ mess lựa chọn các cố gắng để làm việc với keo nóng. | Chapter 9 Creating Selections On the Web Site You can try your hand at creating this selection by downloading Figure 9-16 from the Web site. Caution As you work with the anchors in the Magnetic Lasso tool remember that the tool itself is still carrying a selection line that leaves a wake of anchors no matter where you take it. If you are not careful you ll create a selection mess reminiscent of trying to work with hot glue. Your selection is open and changeable until you close it by either returning to the beginning and clicking the first anchor point or double-clicking to release the selection. After you ve done that the anchor points disappear and your selection is created. Refining Your Selection Every once in a while you have one of those lottery-winning green-light hitting pick-the-fastest-checkout-line kind of days. The rest of the time you have to make adjustments to your selection after the first try. The first step is to actually add and subtract areas to and from your selection that weren t right the first time and you can do this in lots of different ways. After your selection border is right where you want it the next step is to refine the edges of your selection so that whatever it is you want to do with that selected area the changes blend right in. Adjusting a selection After you ve made your initial selection chances are good that you need to add areas into the selection or subtract areas from the selection. You can do this in several ways. First you can use the selection tools. Second you can transform your selection. Third you can create and adjust a path. And last and probably the most precise way is to use the Quick Mask mode and paint areas in or out of your selection. Using the selection tools As I ve already shown you all the selection tools have the option to either add to or subtract from the selection. It doesn t matter what tool you used to create the original selection you can use any other selection tool to add to or subtract from that
