Stroke Selection With a Line
Photoshop CS6 Tutorial
How to Stroke a Selection in Photoshop
In Photoshop, you can make a selection, then apply a stroke to the selection. It can be used for geometric and free form shapes.
In addition to stroking a selection with a line, you can also make a custom brush follow a path. For more information, see topic, Stroking a Path With a Brush.
Open a new document in Photoshop (File > New). Set the size to 500 pixels by 500 pixels at 72 ppi. Set Background Contents to White.
Add a selection to the document by choosing the Elliptical Marquee tool (m key) and click-dragging in the workspace.
To open the stroke dialog box, choose Edit > Stroke.
In the top portion of the box you can set the Stroke Width and Color.
Location is used to position the line Inside, Centered or Outside the selection.
Blending and Opacity are similar to Photoshop's layer options.
Once you have set the options, press OK to stroke the selection.
Stroking a Single Line
In the Marquee tool choices, you can select Rectangular, Elliptical, Single Row or Single Column. Choose either Single Row or Single Column and drag a line in the document. Choose Edit > Stroke and in the options set the location to Center. Click OK and a line is drawn on the selection.
