A path created with the Pen tool does not become an image element until you stroke or fill it. The Fill Path command fills a path with pixels using a specified color, a state of the image, a pattern, or a fill layer.

Note:
When you fill a path, the color values appear on the active layer. Make sure that a standard or background layer is active before completing the steps below. (You cannot fill a path when a mask, text, fill, adjustment, or Smart Object layer is active.)
-
-
For Use, choose the contents for the fill. (See Fill a selection or layer with color.)
-
Choose a blending mode for the fill. (See Blending mode descriptions.)
-
Choose Preserve Transparency to limit the fill to layer areas that contain pixels. (See Lock layers.)
-
Feather Radius
Defines how far inside and outside the selection border the feather edge extends. Enter a value in pixels.
Anti-aliased
Creates a finer transition between the pixels in the selection and the surrounding pixels by partially filling the edge pixels of the selection.
For more information on these options, see Soften the edges of selections.
The Stroke Path command paints the border of a path. The Stroke Path command allows you to create a paint stroke (using the current settings for your painting tools) that follows any path. This command is completely different from the Stroke layer effect, which doesn’t mimic the effect of any of the painting tools.
Note:
When you stroke a path, the color values appear on the active layer. Make sure that a standard or background layer is active before completing the steps below. (You cannot stroke a path when a mask, text, fill, adjustment, or Smart Object layer is active.)

-
Select the painting or editing tool you want to stroke the path. In the options bar, set the tool options, and specify a brush.
For information on specific tool settings, see Smudge image areas and About painting tools, options, and panels.

Alt-click (Windows) or Option-click (Mac OS) the Stroke Path button
