Initializes a new
Leadtools.ImageProcessing.Effects.SpatialFilterCommand class object with explicit parameters.
Supported in Silverlight, Windows Phone 7
Syntax
Parameters
- divisor
- Number used to divide the sum of weighted values.
- bias
- Number added to the weighted average.
- matrix
- The array of weighting factors. The factors apply to pixels in the neighborhood read left to right and top to bottom, as shown below
