Box Blur

A uniform blur that is quicker to render. At low iteration counts it has a slightly “boxy” character; with more iterations the result smooths out and approaches the look of a Gaussian Blur.

Blur Radius sets how far the blur reaches.

Iterations controls how many times the blur is applied — higher counts produce a cleaner, softer result at the cost of render time.

Blur Dimensions restricts the blur to horizontal only, vertical only, or both.

Repeat Edge Pixels controls what happens at the composition edge — when off, the blur darkens near the edge.
