    • Method Summary

      All Methods Static Methods Concrete Methods 
      Modifier and Type Method Description
      static void main​(java.lang.String[] arg)
      Read a DICOM image input format file and convert floating point pixel data to scaled integer values or vice versa.
      static void performIntegerScaling​(java.lang.String inputFileName, java.lang.String outputFileName)
      Read a DICOM image with grayscale floating point PixelData and scale it to integer values sufficient to represent the dynamic range.
      static void reportOnRoundTrip​(double input, double slope, double intercept, java.lang.String message)  
      static void reverseIntegerScaling​(java.lang.String inputFileName, java.lang.String outputFileName, boolean toDouble)
      Read a DICOM image with grayscale integer PixelData and scale it to single or double length floating point values based on the Rescale Slope and Intercept.

      • reportOnRoundTrip

        public static void reportOnRoundTrip​(double input,
                                     double slope,

      • performIntegerScaling

        public static void performIntegerScaling​(java.lang.String inputFileName,
                                         java.lang.String outputFileName)
                                  throws DicomException,
                                         java.io.FileNotFoundException,
                                         java.io.IOException

        Read a DICOM image with grayscale floating point PixelData and scale it to integer values sufficient to represent the dynamic range.

        The dynamic range of the input is mapped to the full range of the short unsigned integer putput pixel values (0 to 65535)

        The scaling values are recorded in Rescale Slope and Intercept.

        Parameters:
        inputFileName - the input file name
        outputFileName - the output file name
        Throws:
        DicomException
        java.io.FileNotFoundException
        java.io.IOException

      • reverseIntegerScaling

        public static void reverseIntegerScaling​(java.lang.String inputFileName,
                                         java.lang.String outputFileName,
                                         boolean toDouble)
                                  throws DicomException,
                                         java.io.FileNotFoundException,
                                         java.io.IOException

        Read a DICOM image with grayscale integer PixelData and scale it to single or double length floating point values based on the Rescale Slope and Intercept.

        Parameters:
        inputFileName - the input file name
        outputFileName - the output file name
        toDouble - if true make double else float pixel values
        Throws:
        DicomException
        java.io.FileNotFoundException
        java.io.IOException

      • main

        public static void main​(java.lang.String[] arg)

        Read a DICOM image input format file and convert floating point pixel data to scaled integer values or vice versa.

        Parameters:
        arg - two or three parameters, an optional direction argument (toFloat|toInt, case insensitive, defaults to toInt), the inputFile, and the outputFile
