Box Blur effect
Box Blur is similar to Fast Blur and Gaussian Blur,
but Box Blur has the added advantage of an Iterations property,
which allows you to control the quality of the blur.
This effect works with 8-bpc, 16-bpc, and 32-bpc color.
- Iterations
- How many times
the blur is sequentially applied to the image. A value around 3
gives a blur similar in quality to Fast Blur. A higher number of
iterations creates smoother transitions between colors and increases
the blur, but it also increases the render time. The default value
creates boxy results.
