Supported ISO versions

Modality	ISO version
Finger	ISO19794_4_2011
Iris	ISO19794_6_2011
Face	ISO19794_5_2011

Note: JPEG2000 will be converted to JPEG.

Sample code

To convert from ISO format to image:

ConvertRequestDto convertRequestDto = new ConvertRequestDto();
convertRequestDto.setVersion("ISO19794_4_2011");
convertRequestDto.setInputBytes(<ISO bytes>);  
byte[] image = FingerDecoder.convertFingerISOToImageBytes(convertRequestDto);
BufferedImage image = FingerDecoder.convertFingerISOToBufferedImage(convertRequestDto);

ConvertRequestDto convertRequestDto = new ConvertRequestDto();
convertRequestDto.setVersion("ISO19794_6_2011");
convertRequestDto.setInputBytes(<ISO bytes>);
byte[] image = IrisDecoder.convertIrisISOToImageBytes(convertRequestDto);
BufferedImage image = IrisDecoder.convertIrisISOToBufferedImage(convertRequestDto);

ConvertRequestDto convertRequestDto = new ConvertRequestDto();
convertRequestDto.setVersion("ISO19794_5_2011");
convertRequestDto.setInputBytes(<ISO bytes>);
byte[] image = FaceDecoder.convertFaceISOToImageBytes(convertRequestDto);
BufferedImage image = FaceDecoder.convertFaceISOToBufferedImage(convertRequestDto);
