Function stack_blur 

pub fn stack_blur(
    image: &mut BlurImageMut<'_, u8>,
    radius: AnisotropicRadius,
    threading_policy: ThreadingPolicy,
) -> Result<(), BlurError>

Fastest available blur option

Arguments

• image - mutable buffer contains image data that will be used as a source and destination.
• radius - radius almost is limited to 1449, minimum is one.
• threading_policy - Threads usage policy.

Complexity

O(1) complexity.
