Enum FilterSource 

pub enum FilterSource {
    SourceGraphic,
    SourceAlpha,
    BackgroundImage,
    BackgroundAlpha,
    FillPaint,
    StrokePaint,
}

Filter input sources.

Defines the various built-in sources that can be used as filter inputs, matching the SVG filter primitive input types. These represent implicit inputs available to any filter primitive without requiring previous operations.

Variants

SourceGraphic

The original graphic content being filtered.

This is the default input - the rendered result of the element the filter is applied to, including all its fill, stroke, and content.

SourceAlpha

Alpha channel only of the original graphic.

Useful for creating effects based on shape/transparency, such as shadows that follow the element’s outline.

BackgroundImage

Background image content behind the filtered element.

Allows filters to incorporate or blend with content behind the element. Not always available depending on the rendering context.

BackgroundAlpha

Alpha channel only of the background image.

The transparency mask of the background content.

FillPaint

The fill paint of the element as an image input.

For elements with gradient or pattern fills, this provides access to the fill as a filter input.

StrokePaint

The stroke paint of the element as an image input.

For elements with gradient or pattern strokes, this provides access to the stroke as a filter input.
