Create Halo & Neon Glow Outline Effects
Find solid-color outlines too monotonous? Then add a soft, diffused halo effect to instantly enhance the visual appeal, separating the subject from the background and creating a sense of depth. This atmospheric outline style is perfect for designing modern neon-style graphics, eye-catching game avatars, or creating atmospheric promotional materials. By adjusting the radius, color, and transparency of the Halo Effect, you can evolve a simple border into a professional studio-backlight effect.
Design Multi-Layer Outlines with Gradients
Why limit your design to a single border? Unleash your creativity and layer multiple outlines to create complex and vibrant photographic effects. Easily create various popular outline styles, such as "double-stroke" sports fonts, rainbow outlines, or brand-specific color schemes, using advanced linear gradients (with up to 6 color transition points). With Add Multi Outline to Image, combined with flexible multi-color options, you can create limitless creative outline art.
