Import Packages

First, make sure to import the required packages for your Java project:

import com.aspose.imaging.Image;
import com.aspose.imaging.fileformats.dicom.DicomImage;
import com.aspose.imaging.imageoptions.BmpOptions;

Now that we’ve covered the prerequisites and imports, let’s break down the process of image brightness adjustment into a step-by-step guide:

Step 1: Define the File Paths

To get started, define the paths for your input and output files. Replace "Your Document Directory" with the actual path to your working directory.

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

Step 2: Load the DICOM Image

Use Aspose.Imaging to load your DICOM image. This can be done with the following code:

try (DicomImage image = (DicomImage) Image.load(inputFile)) {
    // Your code for image processing goes here.
}

Step 3: Adjust the Brightness

Inside the try block, adjust the brightness of the loaded image. You can control the degree of brightness adjustment by specifying the value within the adjustBrightness method. For instance, to increase brightness by 50, use:

image.adjustBrightness(50);

You can also decrease the brightness by specifying a negative value.

Step 4: Save the Resultant Image

Now that you’ve adjusted the brightness, it’s time to save the modified image. Use the following code to save the image with the desired format and options:

image.save(outputFile, new BmpOptions());

That’s it! You’ve successfully adjusted the brightness of your image using Aspose.Imaging for Java.
