How to read GIF files in Java (Tutorial)

In this article, we will show you how to read GIF files in Java. We also have a related article covering how to write GIF files in Java.

GIF files can be read directly by Java’s own ImageIO class and we will also show you how to read them in JDeli.

How to read a GIF image in Java with ImageIO

1. Create a File handle, InputStream, or URL pointing to the raw GIF image.
2. ImageIO will now be able to read a GIF file into a BufferedImage.

and the Java code to read GIF with ImageIO…

File gifFile = new File("/path/to/image.gif");

BufferedImage image = ImageIO.read(gifFile)

How to read a GIF image in Java with JDeli

1. Add JDeli to your class or module path. (download the trial jar).
2. Create a File handle or InputStream pointing to the raw GIF image. You can also use a byte[] containing the image data.
3. Read the GIF image into a BufferedImage

and the Java code to read GIF with JDeli…

File gifFile = new File("/path/to/image.gif");

BufferedImage image = JDeli.read(gifFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(dicomImageFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(heicImageFile);

// Write an image
JDeli.write(bufferedImage, "heic", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(jpegImageFile);

// Write an image
JDeli.write(bufferedImage, "jpeg", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(jpeg2000ImageFile);

// Write an image
JDeli.write(bufferedImage, "jpx", outputStreamOrFile);

// Write an image
JDeli.write(bufferedImage, "pdf", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(pngImageFile);

// Write an image
JDeli.write(bufferedImage, "png", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(tiffImageFile);

// Write an image
JDeli.write(bufferedImage, "tiff", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(webpImageFile);

// Write an image
JDeli.write(bufferedImage, "webp", outputStreamOrFile);
