Solid Border is a powerful filter for Adobe Photoshop for creating precision borders around images with proportionally-accurate values.
Solid Border provides full horizontal and vertical width adjustment combined with adjustable color intensity. You can enable horizontal and vertical locks for uniform border widths. Additionally, Solid Border allows you to force an aspect ratio of 1:1 or use the image’s own aspect ratio for horizontal and vertical border thickness. Units can be in percentage or pixels for precise HTML development.
Solid Border supports custom color and transparency.
