Blurs an image. We convolve the image with a Gaussian operator of the given radius and standard deviation (sigma). For reasonable results, the radius should be larger than sigma. Use a radius of 0 and selects a suitable radius for you.
- radius
- The radius of the Gaussian, in pixels, not counting the center pixel.
- sigma
- The standard deviation of the Gaussian, in pixels.
- channel
- Provide a channel constant that is valid for your channel mode.
