DynamicBinaryCommand Constructor(Int32,Int32)
See Also  Example



dimension
Dimensions of the neighborhood used when evaluating each pixel (Dimension x Dimension), in pixels. This should be at least 1.
localContrast
Local contrast threshold. If the contrast of the area surrounding the pixel is less than the LocalContrast property, the pixel is converted to black or white using a global pre-calculated threshold. If the contrast of the area surrounding the pixel is higher than the LocalContrast property, the local threshold value is calculated and used. The range for the LocalContrast property is 0 to 255 for 8-bit, 0 to 4095 for 12-bit and 0 to 65535 for 16-bit.
Initializes a new DynamicBinaryCommand class object with explicit parameters. Supported in Silverlight, Windows Phone 7

Parameters

dimension
Dimensions of the neighborhood used when evaluating each pixel (Dimension x Dimension), in pixels. This should be at least 1.
localContrast
Local contrast threshold. If the contrast of the area surrounding the pixel is less than the LocalContrast property, the pixel is converted to black or white using a global pre-calculated threshold. If the contrast of the area surrounding the pixel is higher than the LocalContrast property, the local threshold value is calculated and used. The range for the LocalContrast property is 0 to 255 for 8-bit, 0 to 4095 for 12-bit and 0 to 65535 for 16-bit.

Example

Run the DynamicBinaryCommand on an image.

   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg"))

   ' Prepare the command
   Dim command As DynamicBinaryCommand = New DynamicBinaryCommand(8, 16)
   ' convert it into a black and white image without changing its bits per pixel.
   command.Run(leadImage)
   codecs.Save(leadImage, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24)
