MinMaxBitsCommand Class

Gets the low and high bits of the values present in a 12 or 16-bit grayscale or a 48 or 64-bit color image. This class is available in the Medical Toolkits.
public class MinMaxBitsCommand : RasterCommand 
@interface LTMinMaxBitsCommand : LTRasterCommand

    extends RasterCommand 
public ref class MinMaxBitsCommand : public RasterCommand   
class MinMaxBitsCommand(RasterCommand): 
  • The minimum and maximum bit values can be used to specify the range of useful bits and to create a lookup table, for use in the WindowLevelCommand class.
  • This command supports 12 and 16-bit grayscale images. Support for 12 and 16-bit grayscale images is available only in the Document/Medical toolkits.
  • This command does not support 32-bit grayscale images.
  • LEADTOOLS supports two types of LUTs for 10-16-bit grayscale images (8-bit LUT and 16-bit LUT). Typical grayscale image display and processing is done using an 8-bit LUT. But, you can also use a 16-bit LUT, which offers more precision. Some special video cards and monitors also support display of grayscale images using a 16-bit LUT.

Run the MinMaxBitsCommand on an image and gets the minimum and maximum bits for an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
public void MinMaxBitsCommandExample() 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Beauty16.jpg")); 
   // Prepare the command 
   MinMaxBitsCommand command = new MinMaxBitsCommand(); 
   int MinimumBit = 0; //the low bit variable. 
   int MaximumBit = 0; //the high bit variable. 
   //Get min/max bits. 
   MinimumBit = command.MinimumBit; 
   MaximumBit = command.MaximumBit; 
   MessageBox.Show("The Minuimum Bit is : " + MinimumBit.ToString() + ", The Maximum Bit is : " + MaximumBit.ToString());
