dcm4che - Creation of multi-frame dicom image using DCM4CHE3(JAVA) -


i trying create multiframe dicom file multiple jpeg file writing them using imagewriter writer.canwritesequence() giving false not able write jpeg file multiframe dicom file there way can create multiframe dicom file jpeg image or bufferedimage

before run code please install java advanced imaging image i/o tools 32 bit version 1.0_01 java advanced imaging image , try run code using java 32 bit version

  • a) jai imageio library not installed;
  • b) jai imageio installed has no values set in path environment variable;
  • c) dll files jai native code cannot found (wrong installation);
  • d) windows 64bits (it work win32);
