Selecting all pixels in an image
You can apply painting tools and filters to an entire image without
first making a selection. But you can also select all the pixels in an
image when you want to work with them as a selection. To select all
pixels, with a paint object in edit mode, choose Image > Select > All.
A selection border appears around the entire image.
Using selection tools
You can use the Marquee, Oval Marquee, Row Selection, Column
Selection, and Lasso tools to select areas in images.
The Marquee tool selects rectangular areas. The Oval Marquee tool
selects oval areas. The Column Selection tool selects a single vertical
column of pixels. The Row Selection tool selects a single horizontal
row of pixels. The Lasso tools selects odd-shaped areas.
The Marquee, Oval Marquee, Row Selection, and Column Selection
tools are located in a toolbar that pops out from the Painting toolbar.
The Lasso tools are separate icons in the Painting toolbar.
These selection tools let you select any part of an image, from one
pixel to all the pixels in the image. By using modifier keys with these
tools, you can add to and subtract from selections, and select the
overlapping area of two selections.
By subtracting a circle from a larger circle, for example, you can
make a ring-shaped selection with an unselected area inside. See
Modifying selections at the end of this section.
To select rectangular or oval areas
1
Select the Marquee tool or the Oval Marquee tool. If the paint
object isnt in edit mode, click it.
2
Drag diagonally in the image; a selection rectangle or oval
expands as you drag away from the starting point. When you release
the mouse button, a dashed border outlines the selected area.
To make a square selection: If no selection exists, press Shift
and drag the Marquee tool in an image. If a selection exists in the
image, pressing Shift adds to the selection.
To make a circular selection: If no selection exists, press Shift
and drag the Oval Marquee tool in an image. If a selection exists in
the image, pressing Shift adds to the selection.
