OpenCV codecs - ImageInputStream to BufferedImage error

[Pavel Navrkal]

Hi Nicolas,

if I use dcm4che with OpenCV codecs, I have problem to convert ImageInputStream created from general InputStream to jpeg. The error ocures if:

- ImageInputStream is constructed with general java InputStream, not with File() as input

- Input DICOM image is multiframe in jpeg TS (MF IVRLE files works OK)

I get this error:

Minimal example java code:

import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.IOException;
import java.nio.file.Files;

import javax.imageio.ImageIO;
import javax.imageio.ImageReader;
import javax.imageio.stream.ImageInputStream;

public class Test {

    public static void main(String[] args) throws IOException {
        ImageReader reader = ImageIO.getImageReadersByFormatName("DICOM").next();

        ByteArrayInputStream is = new ByteArrayInputStream(Files.readAllBytes(new File("/tmp/test.dcm").toPath()));

        try (ImageInputStream iis = ImageIO.createImageInputStream(is)) {
            reader.setInput(iis, false);
            reader.read(1, reader.getDefaultReadParam());
        }
    }
}

Tested DICOM image is in attachement.

Prefer to use DicomInputStream instead of ImageIO.createImageInputStream() because there is a cache mechanism.

import java.awt.image.BufferedImage;

import java.io.ByteArrayInputStream;

import java.io.IOException;

import java.nio.file.Files;

import java.nio.file.Paths;

import javax.imageio.ImageIO;

import javax.imageio.ImageReader;

import org.dcm4che3.io.DicomInputStream;

public class Test {

    public static void main(String[] args) throws IOException {

        ImageReader reader = ImageIO.getImageReadersByFormatName("DICOM").next();

        

        byte[] data = Files.readAllBytes(Paths.get("/tmp/test.dcm"));

        ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(data);

        DicomInputStream dicomStream = new DicomInputStream(byteArrayInputStream);

        reader.setInput(dicomStream);

        BufferedImage bi = reader.read(1, reader.getDefaultReadParam());

    }

}

Wrapping the stream by DicomInputStream fix the issue.

Thanks.
