Add Border
This transformation adds a border around an image. The border margin widths are individually selectable and you can specify either a solid border color or a border image that is tiled as necessary to create the border. The border can be rectangular, oval or diamond shaped, and you can control the softness of the blend between the image and the border.
To place a simulated mat around an image or for more extensive framing effects, you can use the Frame transformation.
Border Widths
These controls let you specify Unequal, Equal or Equal except for bottom border widths. The text controls let you specify the actual border widths in %, pixels, in, cm or mm. If you select % as the units, border widths are specified as a percentage of the input image width and border heights as a percentage of the input image height.
Border Color
This control lets you set the border as either a solid color or as an image that is tiled to fill the background behind the image. If you select an image, the Scale slider is displayed to let you set a magnification factor for the image.
Shape
This controls lets you specify the shape of the opening in the border that the image will show through. The options are Rectangle, Rounded, Beveled, Indented, Inverse Rounded, Oval or Diamond. Note that any shape but rectangular can obscure part of the image, so you may need to leave some room when you crop your original.
Rectangle Rounded Beveled Indented Inverse Rounded Oval Diamond
Corner Radius
If you select Rounded, Beveled, Indented or Inverse Rounded, this slider is displayed that lets you specify how much you want the corners rounded, beveled or indented.
Softness
This slider determines how much the transition between the border and the image is smoothed. A value of 0% produces a hard edge between the border and the image. Larger values produce softer edges. Note that the soft part of the border hides the outer edge of the image, so you should leave some extra room when you crop your original.
