Chapter 5. Select - Pg. 166

166 Chapter 5. Select When a layer or part of a layer is selected, only that area is editable--the rest of the image is protected. A selection border has a "marching ants" marquee. This chapter covers the creation of selections using the Rectangular Marquee, Elliptical Marquee, Lasso, Polygonal Lasso, Magic Wand, and Magnetic Lasso tools, as well as the Color Range and Extract commands. You will also learn how to create selections of various shapes; how to select by color; how to deselect, reselect, invert, or delete a selection; how to move or hide a selection marquee; how to transform, add to, or subtract from a selection; and how to create a vignette. Creating selections A selection contains pixels from whichever layer is currently active. If the Move tool is used to move a selection on the Background of an image, the current Background color will be applied automat- ically to the exposed area. If a selection is moved on a layer using the Move tool, the exposed area will become transparent. (See Chapter 7, "Layers.") Tip A selection can be converted into a path for precise reshaping, and then converted back into a selection (see pages 284 and 294). Quick Masks, which function like selections but can be painted on an image, are covered in Chapter 15. To select an entire layer: Choose a layer, then choose Select > All (Ctrl-A/Cmd-A). A marquee will surround the entire layer. or To select only opaque pixels--not any transparent areas--on a layer, Ctrl-click/Cmd-click the layer on the Layers palette Transparency. ­ . Or right-click/Ctrl-click a layer thumbnail and choose Select Layer
