Function fast_blur

Source 
pub fn fast_blur<P>(
    input_buffer: &ImageBuffer<P, Vec<<P as Pixel>::Subpixel>>,
    sigma: f32,
) -> ImageBuffer<P, Vec<<P as Pixel>::Subpixel>>

Expand description

Approximation of Gaussian blur.

ยงArguments

  • image_buffer - source image.
  • sigma - value controls image flattening level.

This method assumes alpha pre-multiplication for images that contain non-constant alpha.

This method typically assumes that the input is scene-linear light. If it is not, color distortion may occur.
