Usage context

SourceGraphic

This keyword represents the graphics elements that were the original input into the <filter> element.

This keyword represents an image snapshot of the SVG document under the filter region at the time that the <filter> element was invoked.

BackgroundAlpha

Same as BackgroundImage except only the alpha channel is used.

FillPaint

This keyword represents the value of the fill property on the target element for the filter effect- In many cases, the FillPaint is opaque everywhere, but it might not be the case if a shape is paint with a gradient or pattern which itself includes transparent or semi-transparent parts-

StrokePaint

This keyword represents the value of the stroke property on the target element for the filter effect. In many cases, the StrokePaint is opaque everywhere, but it might not be the case if a shape is paint with a gradient or pattern which itself includes transparent or semi-transparent parts.
