color
Color used for showing the variances in the image.
sourceLowBit
Position of the start bit that will construct the mask. The position is a zero based number. This parameter only accepts positive values.
sourceHighBit
Position of the end bit that will construct the mask. This is inclusive (it is part of the mask). The value should not be less than sourceLowBit. You can also pass -1, which is interpreted as "highest bit" (SourceImage->BitsPerPixel - 1). This parameter only accepts positive values.
threshold
Value that indicates the threshold for showing the image variances. If the mask value is greater or equal to the threshold value then the pixel will be colored using Color. See Combine for more details. This parameter only accepts positive values.
combine
A flag which tells how to color the output pixels:
  1. Pixels with values greater than or equal to the threshold value are set to the value in the color parameter(if combine is set to false) or AND-ed with color (if combine is true). In this case, the source pixel is first converted to grayscale 24-bit and then AND-ed with color.
  2. Pixels with values less than the threshold value are set to black (if combine is set to false) or The RGB pixel value will be the same as the high byte source pixel value (if combine is true). That is R = G = B = High byte values of the source pixel.
Initializes a new Leadtools.ImageProcessing.Core.SelectDataCommand class object with explicit parameters.

Example

Run the Leadtools.ImageProcessing.Core.SelectDataCommand on an image.

   ' Prepare the command

   command.Run(leadImage)
   codecs.Save(command.DestinationImage, Path.Combine(LEAD_VARS.ImagesDir, "SelectDataResult.bmp"), RasterImageFormat.Bmp, 24)
