This quick tutorial provides details on how to create animated GIF in Java by adding different types of images like PNG, JPEG, etc. from the disk. While using Java GIF creation process is made simple and easy to learn by providing configuration details, program flow, and detailed description. You can add as many images as required and may apply different filters also according to the application requirements.

Steps to Create Animated GIF in Java

1. Establish the project environment to use Aspose.Imaging for Java from the Maven repository
2. Prepare the list of image files from the desired directory
3. Initialize a list of RasterImage class objects
4. Iterate through all the image files list and load them all into the list of RasterImage
5. Create a GIFImage object using the first RasterImage in the list
6. Iterate through the rest of the images in the list and add them all to the existing GIFImage object
7. Save the output GIF image on the disk after adding all the images

These steps describe how using Java create animated GIF by sharing a step-by-step approach. First, you need to load all the images from the target directory into a list of RasterImage objects. In the next step, create a GIF image using the first raster image in the list and then add all the rest of the images loaded from the disk to this newly created GIF image before saving it on the disk.

Code to Create Animated GIF in Java

These lines of code in Java create GIF by loading all the images into the RasterImage class objects and provide control to customize the loaded images like adjusting the brightness, contrast, Gamma, cropping the portion of the image, filtering rectangular area segments, normalizing angles and rotating the image to name a very few before adding to the GIF image. Similarly, before saving the output GIFImage you can resize it, rotate the entire GIF, flip it, set background color, set frame time in milliseconds, set loops count, set transparent color, and many more.
