Border Geometry, CSS Box Model & Print Matting Guide
When applying corner radius in HTML5 Canvas, modern browsers use the native
roundRect() path definition. By executing ctx.clip() with sub-pixel floating point calculations, the browser's hardware graphics acceleration performs multi-sampled anti-aliasing (MSAA), eliminating jagged stair-step artifacts common in traditional bitmap editing.
In web browsers, CSS
box-sizing: border-box insets borders inside existing element boundaries, while content-box adds to layout width without affecting image pixel data. Our Expand Dimensions Mode calculates physical canvas enlargement: Width = SourceWidth + (BorderWidth * 2) + (Matting * 2). This guarantees zero cropping or loss of your original subject pixels.
Fine-art galleries frequently utilize passe-partout matting to direct the viewer's focus inward toward the composition. A classic museum standard employs a border equal to 8% to 15% of the shortest image side. For Polaroid style frames, the bottom margin is deliberately weighted 2.5x to 3x wider than the sides to create an organic vintage instant-camera aesthetic.
Every single operation—including image parsing, canvas clipping, gradient calculation, and file encoding—executes strictly inside your browser's V8/SpiderMonkey engine. Not a single byte of your photos, screenshots, or artwork is transmitted to any external server or API.
