You can also reapply color or a paint effect along the edges of an editable area. You can apply color or a paint effect along the edges of an editable area to emphasize or blend the boundary between the editable and protected areas. For example, when you smooth the edges of an editable area, protected areas that are isolated within the editable areas are often removed. Smoothing is useful when you work with complex color masks.

If the editable pixels outnumber the protected pixels, the editable area is expanded if the protected pixels outnumber the editable pixels, the protected area is expanded. For example, if you specify 10 as the radius value, 10 pixels to the left and 10 pixels to the right of the edge are checked. Smoothing averages the grayscale values of a specified number of pixels at the edge of an editable area. You can smooth the edges of an editable area to remove sharp angles. For example, if you set a threshold value of 110, all pixels within the editable area that have a grayscale value of less than 110 are protected, and all pixels within the area that have a grayscale value of more than 110 are editable. The threshold value you specify determines where along the feathered edge you want the new, unfeathered edge to be created. Pixels in the feathered editable area have a grayscale value ranging from 0 (black and fully protected) to 255 (white and fully editable). You can remove the feathering from the edges of an editable area and create a new, sharper edge by setting a threshold value. Left to right: Before and after feathering the edges of an editable area From the mask marquee, the feathering direction can go into the protected areas, into the editable areas, or into both areas for an equal distance. You can specify the width of the feathered area as well as the feathering direction, which determines where the feathering is located relative to the mask marquee.

Anti-aliasing makes some of the pixels located on the inside edge of an editable area semitransparent, creating a smoother outline.įeathering gradually increases the transparency of the pixels along the edge of an editable area to soften the edge between the protected and editable areas. You can use anti-aliasing to avoid the appearance of jagged edges of editable areas that have curved and diagonal lines. You can customize the transition between a protected area and an editable area by adjusting the edges of these areas.
