Groovy Script to store an image file as .jpg from http response body with content type as image/jpeg

An API GET response returns an image in the body, like this: This is not an attachment.

HTTP/1.1 200 OK
Server: Apache-Coyote/1.1

Postman decodes the image an displays it, it is an animal in this case.

I have to store the response as an image file (.jpg) using a groovy script in soapUI(soapUI is used to test the API)

This is what I've tried in a Groovy Script step, but the image saved is unintelligible malformed.

def getImageResponse = new String(testRunner.testCase.testSteps["GET Image"].testRequest.response.responseContent);
byte[] imageInByte;
BufferedImage originalImage = ByteArrayInputStream(getImageResponse.getBytes()));

// convert BufferedImage to byte array
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write(originalImage, "jpg", baos);
imageInByte = baos.toByteArray();

// convert byte array back to BufferedImage
InputStream inRead = new ByteArrayInputStream(imageInByte);
BufferedImage bImageFromConvert =;

ImageIO.write(bImageFromConvert, "jpg", new File("C:\\animal.jpg"));

 I guess that what I am doing to save the image in .jpg is not correct. Can someone help?

Attach is the raw response.

Thanks in advance.

This is how I did this. From the Script Assertion of the http GET request. Hope It helps someone.

def ins = context.httpResponse.getRawResponseBody();
def isImageSaved = false;
InputStream inputStream;
FileOutputStream outputStream;
if (ins){
    try {
        inputStream = new ByteArrayInputStream(ins);
        outputStream = new FileOutputStream(new File(context.expand("C:\\animal.jpg")));
        int read = 0;
        byte[] bytes = new byte[1024];

        while ((read = != -1) {
            outputStream.write(bytes, 0, read);
        isImageSaved = true;

    }catch (Exception e){
        log.error e;
} else {
    log.error "image does not exist...";

context.testCase.setPropertyValue("isImageSaved", isImageSaved.inspect());
