Parameters

page
Page to process.
radius
Defines the neighborhood to be considered for each pixel.
channels
Defines image channels to apply the transform to.
Remarks
This method makes images look softer and out of focus.

The radius parameter corresponds to the Standard Deviation (Sigma) in Gaussian transform. It can range from 0.1 to 500. Typical values for high-resolution images range from 1.0 to 2.0. Larger values will cause greater softening. On the other hand, smaller values are faster. The width of the area considered for each pixel is approximately 6 * radius.

The method allows to specify the range of channels to blur.
