Function image::imageops::blur

pub fn blur<I: GenericImageView + 'static>(
    image: &I, 
    sigma: f32
) -> ImageBuffer<I::Pixel, Vec<<I::Pixel as Pixel>::Subpixel>> where
    I::Pixel: 'static,
    <I::Pixel as Pixel>::Subpixel: 'static, 

Performs a Gaussian blur on the supplied image. sigma is a measure of how much to blur by.
