DICOM Image Gamma Adjustment with Aspose.Imaging for Java

Are you looking to enhance the quality of DICOM images in your Java applications? Aspose.Imaging for Java is a powerful and versatile library that allows you to manipulate and process images, including DICOM format. In this step-by-step tutorial, we will guide you through the process of adjusting the gamma of a DICOM image using Aspose.Imaging for Java.

Prerequisites

Before you get started, make sure you have the following prerequisites in place:

1. Java Development Environment

• Ensure you have Java Development Kit (JDK) installed on your system.

2. Aspose.Imaging for Java Library

• You can obtain the Aspose.Imaging for Java library from the download link.

3. Input DICOM Image

• You should have a DICOM image that you want to process. If you don’t have one, you can easily find sample DICOM images online or use your own.

Import Packages

First, you need to import the required packages for your Java project. Here’s how you can do it:

import com.aspose.imaging.fileformats.dicom.DicomImage;
import com.aspose.imaging.image.Image;
import com.aspose.imaging.imageoptions.BmpOptions;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

Let’s break down the process of adjusting the gamma of a DICOM image into a series of easy-to-follow steps.

Step 1: Set the File Paths

You need to specify the input and output file paths. Replace "Your Document Directory" with the actual directory where your DICOM image is located.

String dataDir = "Your Document Directory" + "dicom/";
String inputFile = dataDir + "image.dcm";
String outputFile = dataDir + "AdjustingGamma.bmp";

Step 2: Load the DICOM Image

Load the DICOM image using Aspose.Imaging’s DicomImage class.

File file = new File(inputFile);

try (FileInputStream fis = new FileInputStream(file)) {
    // Load a DICOM image in an instance of DicomImage
    try (DicomImage image = (DicomImage) Image.load(fis)) {

Step 3: Adjust the Gamma

Now, adjust the gamma of the DICOM image by specifying the desired gamma value (e.g., 50).

        // Adjust the gamma
        image.adjustGamma(50);

Step 4: Save the Resultant Image

Create an instance of BmpOptions for the resultant image and save it.

        // Create an instance of BmpOptions for the resultant image and save the resultant image
        image.save(outputFile, new BmpOptions());
    }
} catch (IOException ex) {
    // Handle any potential exceptions
    com.aspose.imaging.examples.Logger.println(ex.getMessage());
    ex.printStackTrace();
}

That’s it! You’ve successfully adjusted the gamma of a DICOM image using Aspose.Imaging for Java.
