\title{
  Apply a Gaussian blur to an image.
}
\description{
  This filter effect primitive performs a Gaussian blur on the input
  image.
}
\usage{
feGaussianBlur(input = NA, sd = 0, ...)
}
\arguments{
  \item{input}{
    Identifies an input for this filter primtive. See
    \code{\link{filterInputs}}.
  }
  \item{sd}{
    The value of \code{sd} can be a numeric vector with either one or
    two elements. If two numbers are provided, the first number
    represents a standard deviation value along the x-axis of the
    current coordinate system and the second value represents a standard
    deviation in Y. If one number is provided, then that value is used
    for both X and Y.
  }
