Plugin Option: Background Mask

backgroundMask draws a cover or mask over the canvas using compositing operations.

Example

backgroundMask: {
  enable: true,
  composite: "destination-out",
  cover: {
    color: { value: "#000000" },
    opacity: 1,
  },
}

Notes

• Use cover.image to use an image as the mask cover.
• The plugin extends the built-in backgroundMask with additional compositing features.
