What is GIF?

What is GIF?

GIF is a lossless, bitmap image format which became popular on the world wide web because it supports transparency and simple animations in browsers. It can support up to 256 different colours from a 24bit range of RGB values. It uses LZW compression (which was subject to patents owned by Unisys). Issues over this in 1990s, led it to be largely replaced by the PNG format in modern usage.

The file name extension for GIF files is: .gif

What does GIF stand for?

GIF stands for Graphics Interchange Format.

Is GIF a video or an image?

Although GIFs can move they are counted as images, therefore it can be treated as an image.

What is GIF used for?

GIF format is used to show short looping animations, which could be ideal for learning by demonstrating processes and concepts visually.

Is it possible to convert GIF to another file format?

Yes. You can convert GIF to MOV or GIF to WEBP.

How to open GIF files in Java?

There are several commercial GIF solutions available. Our JDeli library allows you to read, write and display GIF files.

Why do developers choose JDeli over free alternatives?

1. Works with newer image formats such as AVIF, HEIC, JPEG XL, WEBP (AVIF next release) that are not supported in Java.
2. Better support than alternatives for JPEG, PNG, TIFF.
3. Process images up to 3x faster than ImageIO and other Java image libraries.
4. Prevent JVM crashes caused by native code in other image libraries such as ImageIO.
5. Image security as JDeli processes images on your servers with no calls to any external system or third party library.

// 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);
