There will be times when the effect you want to add requires an additional image beyond the source graphic. Fortunately SVG provides a way to allow us to load external images inside a filter and make them part of the effect.

SVG Filter Effects—3 Simple Filter Primitives
For the last few weeks I’ve been talking about filters in SVG. I showed you the basics, talked in more detail about the filter element, and last week I discussed the input and output of filter primitives. What I haven’t yet done is talk about any of the primitives in detail.
SVG Filter Primitives—Input and Output
SVG filter primitives are the building blocks to create the effect you desire. You can use multiple primitives inside a single filter for more interesting effects, however, you need to make the different primitives aware of each other.
The SVG Filter Element
SVG filter effects apply graphic operations to images and elements in nondestructive ways. You can add filters to any SVG element or text and even to bitmapped images. Because SVG filters are nondestructive the original image is never changed and you can return to it by removing any filters you’ve added.
An Introduction To SVG Filters
If I asked you to blur an image or make color adjustments to it, you’d probably reach for your favorite image or graphic editing program and rightly so. Effects like these have been created in image editors for years. However, some can now be created without the editor and through code alone.
