How to Resize JP2 Files Using Java

Constructing a website is a complex endeavor where each element holds significance. A crucial aspect in the process of populating web pages revolves around resizing images. Often, the need arises to resize their dimensions and prepare images or photos in varying resolutions. For instance, pages featuring image galleries with previews require small thumbnail files, while pages showcasing main images demand high-resolution versions. For larger files, resizing is essential to reduce total pixel count, thus diminishing file size without significantly compromising image quality. During image resizing, you can also choose the degree of data compression to strike a balance between image size and quality. Reduced image sizes lead to quicker loading times from the internet, enhancing the user browsing experience on your website. In order to merge JP2 files, we’ll use Aspose.Imaging for Java API which is a feature-rich, powerful and easy to use image manipulation and conversion API for Java platform. You can download its latest version directly from Maven and install it within your Maven-based project by adding the following configurations to the pom.xml.

  • About Aspose.Imaging for Java API

    Aspose.Imaging API is an image processing solution to create, modify, draw or convert images (photos) within applications. It offers: cross-platform Image processing, including but not limited to conversions between various image formats (including uniform multi-page or multi-frame image processing), modifications such as drawing, working with graphic primitives, transformations (resize, crop, flip&rotate, binarization, grayscale, adjust), advanced image manipulation features (filtering, dithering, masking, deskewing), and memory optimization strategies. It’s a standalone library and does not depend on any software for image operations. One can easily add high-performance image conversion features with native APIs within projects. These are 100% private on-premise APIs and images are processed at your servers.

    JP2 What is JP2 File Format

    JPEG 2000 (JP2) is an image coding system and state-of-the-art image compression standard. Designed, using wavelet technology JPEG 2000 can code lossless content in any quality at once. Moreover, without any substantial penalty in coding efficiency, JPEG 2000 have the capability to access and decode the same content efficaciously into a variety of other resolutions and qualities. The code streams in JPEG 2000 is significantly scalable having regions of interest that provide the facility for spatial random access. Possessing Up to 16384 diverse components with the dimensions in terapixels, and precision that can be high as 38 bits/sample.
