img blur

Blurs images, using either the box blur or gaussian blur method. By default it applies a gaussian blur.

--radius <r>
Set radius of blur (default: 2.0)
--style <option>
Set method used for determining edge values:
clamp — does not blur the edges, corrects for this but may leave the edges looking un-blurred.
ignore — does not blur the edges, leaves them semi-transparent.
wrap — takes colour from the opposing side, so there may be a colour change at the edges.
Perform a box blur. This takes the colour values from surrounding pixels and takes the average.
--gaussian <sigma>
Perform a gaussian blur using the specified sigma (default: 5.0). This takes colour values from surrounding pixels, but unlike box blur the amount contributed gets less for further pixels.
