How to Resize GIF 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 GIF 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.

    GIF What is GIF File Format

    A GIF or Graphical Interchange Format is a type of highly compressed image. Owned by Unisys, GIF uses the LZW compression algorithm that does not degrade the image quality. For each image GIF typically allow up to 8 bits per pixel and up to 256 colours are allowed across the image. In contrast to a JPEG image, which can display up to 16 million colours and fairly touches the limits of the human eye. Back when the internet emerged, GIFs remained the best choice because they required low bandwidth and compatible for the graphics that consume solid areas of colour. An animated GIF combines numerous images or frames into a single file and displays them in a sequence to generate an animated clip or a short video. The colour limitations are up to 256 for each frame and are likely to be the least suitable for reproducing other images and photographs with colour gradient.
