How to read SGI images in Java

37 sec read

SGI icon

In this post, I will show you how to read SGI images in Java.

ImageIO does not support SGI images by default so you will need to use an ImageIO plugin or an external library. I will cover how to use an Open source ImageIO plugin called TwelveMonkeys (which extends ImageIO to add SGI image support), and how to use the JDeli Image Library.

How to read an SGI image in Java with ImageIO

SGI

  1. Download TwelveMonkeys plugin and add to class path.
  2. Create a File handle, InputStream or URL pointing to the raw SGI image.
  3. ImageIO will now be able to read an SGI file into a BufferedImage. This syntax is like so:
    BufferedImage image = ImageIO.read(sgiFileOrInputStreamOrURL)

How to read an SGI image in Java with JDeli

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


Are you a Java Developer working with Image files?

// 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);

What is JBIG2?

JBIG2 is a lossless and lossy compression standard for bi-level images like scanned documents, offering high compression ratios by identifying and encoding similar shapes...

  1. As ImageIO is plugin based, I have written a plugin for the SGI format, that allows ImageIO to read SGI images as easy as:

    BufferedImage image = ImageIO.read(sgiFile);
