Inputs

Image

Image Image with transparent areas

Output

Image Continuous image

Parameters

Iterations:

number of blur iterations

Premultiply:

if set, multiply all partially transparent pixels before processing

Clamp:

if set, clamp all pixel values of input image between 0 and 1

Alpha Threshold:

all pixels with alpha above this value will not be extrapolated, but simply get alpha 1

Note

For example, if Alpha Threshold is 0.75, then all pixels with original alpha 0.75 and higher will keep their RGB values, and their alpha will be set to 1. All other pixels will be extrpolated
