   codecs.ThrowExceptionsOnInvalidImages = True

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

   ' Prepare the command
   Dim command As AutoSegmentCommand = New AutoSegmentCommand

Remarks

The result is applied to the image as a region. This function was designed specifically for CT/MRI images, to segment regions of cancer clusters.

  • Use Leadtools.RasterImage.MakeRegionEmpty to delete the resulting region.
  • The rectangle must not exceed the borders of the image or the function will return an ERROR_INVALID_PARAMETER error and will not execute. This function is available only in the Document/Medical toolkits.
  • This command does not support 32-bit grayscale images.
