Coefficients for the filter at a particular position & width.

float Filter::Coefficients::apply | ( | const float * | array | ) | const |

Multiply an array of pixels by the filter coefficients and return the sum of the results. It is equivalent to the following code:

return sum*normalize;

Note that in many cases your input is a bounded array or is not an array at all. You can either write equivalent code to read your source, or copy it to an array and call this.
