This article covers how to scale image in Java. It explains the environment configuration, the algorithm, and a sample code to upscale image in Java. Moreover, you do not need any advanced or complex image processing tool to embed this feature into your project.

Steps to Scale Photo in Java

1. Prepare the system to work with Aspose.Drawing to upscale images
2. Create an object of the Bitmap class
3. Initiate an instance of the Graphics class while setting the pixel interpolation mode
4. Specify the image scale factor and the coordinates
5. Export the scaled image

These steps summarize the process to scale image without losing quality in Java. Make a few API calls while specifying the image dimensions and rectangular coordinates for the expansion. Subsequently, set the scaling factor and export the output image in PNG or JPG format.

Code to Upscale Image in Java

This code snippet quickly showcases how to up scale image in Java. However, you can further improvise this code snippet by selecting the interpolation mode like bilinear, nearest neighbor, bicubic, etc. Likewise, you may adjust the scaling factor to match your size requirements based on different use cases.
