Bevel
Creates a beveled border around the edges of an image by superimposing an angled frame over the original image. You can adjust the simulated direction of reflected light and the opacity of the bevel to vary the effect.
Adjust this filter using the parameter controls in the Filters Inspector:
Light Angle: Sets the angle at which the light hits the bevel.
Bevel Width: Sets the width of the bevel as a percentage of the area of the layer.
Opacity: Sets the opacity of the bevel, ranging from 0 (invisible) to 1.0 (opaque).
Light Color: Picks the color of the light hitting the bevel border. Expand the color controls to adjust individual Red, Green, and Blue sliders, to more precisely select colors.
Mix: Sets the percentage of the original image to be blended with the beveled image.
