The <mask> element defines an alpha mask for compositing objects into
the background.
Why use a Mask?
Masks are different from clipping paths. While a clipPath is a hard "cookie
cutter" (visible or not), a mask allows for transparency and gradients.
- Luminance Masking: By default, SVG masks use the brightness of the mask's content to determine transparency. White in the mask means the object is fully visible; black means it is fully hidden; grey means it is semi-transparent.
- Complex Fading: Use a
linearGradientinside a mask to make an image fade away gradually.
Examples
# Create a mask that fades from white to black
gradient = Vectored.Elements.LinearGradient.new([
Vectored.Elements.Stop.new(0, "white"),
Vectored.Elements.Stop.new(1, "black")
]) |> Vectored.Elements.LinearGradient.with_id("fade-grad")
mask = Vectored.Elements.Mask.new([
Vectored.Elements.Rectangle.new(0, 0, 100, 100)
|> Vectored.Elements.Rectangle.with_fill("url(#fade-grad)")
]) |> Vectored.Elements.Mask.with_id("my-mask")
# Apply the mask to a shape
Vectored.Elements.Circle.new(50, 50, 40)
|> Vectored.Elements.Circle.with_mask("url(#my-mask)")
Summary
Functions
Append a child element to the mask.
Remove a dataset attribute
Create a new mask with an optional list of children.
Set a dataset attribute. Mimics the DOM Element.dataset API. The key will be converted from camelCase to kebab-case for the data-* attribute.

Functions
Append a child element to the mask.

@spec new([Vectored.Renderable.t()]) :: t()
Create a new mask with an optional list of children.
Set a dataset attribute. Mimics the DOM Element.dataset API. The key will be converted from camelCase to kebab-case for the data-* attribute.
Security
The key is converted to an atom at render time (required by :xmerl).
Never pass untrusted/user-derived strings as key — unbounded distinct
keys exhaust the atom table and crash the BEAM. Use static key names.
