What the SVG Mask Luminance does
Preview an SVG luminance mask where white reveals and black hides artwork. A fade mask can reveal the top of a rectangle while hiding the bottom through a black-to-white gradient Adjust the controls and the preview updates immediately, so you can dial in exactly what you want and copy the result straight into your project — no build step and no account.
One thing to keep in mind: Mask behavior depends on mask-type support; use mask-type luminance when that intent must be explicit.
