Leadtools.ImageProcessing.Core Namespace : 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.

         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()); 
 
         RasterCodecs.Shutdown(); 
      }

Remarks

  • 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.
