Initializes a new
SpatialFilterCommand class object with explicit parameters.
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

Example
Run the SpatialFilterCommand on an image.

Dim codecs As New RasterCodecs()
codecs.ThrowExceptionsOnInvalidImages = True
Dim leadImage As RasterImage = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg")
Dim command1 As SpatialFilterCommand = New SpatialFilterCommand(SpatialFilterCommandPredefined.EmbossSouth)
Dim data() As Integer = command1.Matrix
Dim command As SpatialFilterCommand = New SpatialFilterCommand(command1.Divisor, command1.Bias, data)
command.Run(leadImage)
codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)
RasterCodecs.Shutdown()
