About selections

Since there are two different types of data in your image—bitmap and vector—you need
to use separate sets of tools to make selections of each type. You can use selection borders
to select pixels. When you select pixels, you are selecting resolution dependent infor-
mation in the image. For more information about bitmap images and vector graphics,
see "About bitmap images and vector graphics" on page
You can also create selections using the pen or shape tools, which produce precise
outlines called paths. A path is a vector shape that contains no pixels. (See
copying, and pasting selections and layers" on page
tions or convert selections to paths. (See
borders (Photoshop)" on page
In Photoshop, you can use the Extract command to isolate an object from its background
and erase the background to transparency. You can also make sophisticated selections
using masks. (See "Saving a mask selection" on page

Making pixel selections

You can select pixels in an image by dragging with the marquee tools or lasso tools, or by
targeting color areas with the magic wand tool. In Photoshop, you can also use the Color
Range command. Making a new selection replaces the existing one. Additionally, you can
create selections that add to a selection, subtract from a selection, select an area inter-
sected by other selections, or select the union of a new selection and the current
selection.
Using the Select menu
You can use commands in the Select menu to select all pixels, to deselect, or to reselect.
To select all pixels on a layer within the canvas boundaries:
1 Select the layer in the Layers palette.
2 Choose Select > All.
To deselect selections:
Do one of the following:
Choose Select > Deselect.
•
If you are using the rectangle marquee, rounded rectangle marquee (ImageReady),
•
elliptical marquee, or lasso tool, click anywhere in the image outside the selected area.
To reselect the most recent selection:
Choose Select > Reselect.
