This article contains information on how to change image brightness using Java. It has all the details for IDE, programming steps, and sample code for developing an image brightness editor using Java. You will perform pixel-level operations to modify the brightness as per the requirements.

Steps to Increase Brightness of Image using Java

1. Set the IDE to use Aspose.Imaging for Java to develop an image brightness editor
2. Load the source picture as a generic image type using the image class
3. For pixel-level operations, convert the generic type image to a RasterImage
4. For fast access and operations, cache the image data in memory
5. For brightening the image, set a positive value in the adjustBrightness() method
6. Create a TiffOptions class object for setting parameters such as 8 bits for each color channel
7. Specify the color interpretation mode to RGB using TiffPhotometrics.Rgb enum value
8. Save the image as a TIFF image using the above custom settings

These steps explain the process of changing the photo brightness using Java. Load the source image as a generic image, cast it to RasterImage for pixel-level operations, cache the image into memory for better performance, and call the adjustBrightness() method to set the new brightness for the loaded image. Save the output image as TIFF by setting its properties using the TiffOptions class object; however, you can save the image to any other format or original format if required.

Code to Increase Brightness of Photo using Java

This sample code has demonstrated the process to increase brightness of picture using Java; however, if you want to darken the image, set the value -ve in the adjustBrightness() method. Note that caching the image in memory is an optional step that you may skip as per your requirements.

In this article, we have learned the process of adjusting brightness. To create multipage TIFF, refer to the article on Create multipage TIFF using Java.
