package nvgif - Java bindings for nvgif.c

Source: c/java/nvgif/NVGIFDecoder.java

There is a Java binding for the C implementation. As such, it only supports v1–v3.

It uses Java Native Access (JNA) to call the C dynamic library. It is not considered its own reference implementation because it is simply a binding, nothing more.

To use it, you must download the c/ folder and follow the instructions in the README to build the Java bindings. After that’s done, copy everything inside java/dist to your project.

public class NVGIFDecoder

public static java.awt.image.BufferedImage decode(String filename)

Decodes the image at filename and returns it in the form of a BufferedImage. Under the hood, it uses nvg_decode_image to decode the image, transforms it into a BufferedImage, and then calls nvg_free_image to free the C Image structure.

Example

import nvgif.NVGIFDecoder;
import java.awt.image.BufferedImage;
import javax.imageio.ImageIO;
import java.io.File;

public class NVGIFTest {
    public static void main(String[] args) throws Exception {
        if (args.length < 2) {
            System.err.println("Usage: NVGIFTest input.nvg output.png");
            return;
        }
        BufferedImage img = NVGIFDecoder.decode(args[0]);
        ImageIO.write(img, "png", new File(args[1]));
        System.out.println("Decoded " + args[0] + " and wrote " + args[1]);
    }
}
