Configure JDeli with ImageIO

What is JDeli-ImageIO?

It is JDeli with our ImageIO plugin included so that you can easily download and run your code without having to refactor to work with JDeli.

Although this makes things easier, if you want to reap all the benefits of JDeli, it is recommended you refactor your code to use JDeli.

Getting started

Just as you would with JDeli you need to download the jar:

Download JDeli

You then need to add it to your modulepath.

The jar has been made so that you can choose which formats ImageIO will use JDeli for. It comes with our HEIC encoder and decoder pre-registered so ImageIO will pick up JDeli for writing and reading HEIC.

You can register more formats:

Other available readers are:

• BMP, DCM, EMF, GIF, JPEG2000, JPEGXL, JPEG, PNG, PSD, SGI, TIF, WEBP, WMF

To register them all you use:

ImageIOSupport.registerReaders(ImageIOSupport.InputFormat.values());

And to just register one, you use:

ImageIOSupport.registerReader(ImageIOSupport.InputFormat.PNG);

Other available writers are:

• BMP, GIF, JPEG2000, JPEG, PDF, PNG, TIFF, WEBP

To register them all, you just use:

ImageIOSupport.registerWriters(OutputFormat.values());

And to just register one, you use:

ImageIOSupport.registerWriter(OutputFormat.PNG);

To unregister formats:

//unregistering all readers
ImageIOSupport.unregisterReaders(ImageIOSupport.InputFormat.values());

//unregistering a single reader
ImageIOSupport.unregisterReader(ImageIOSupport.InputFormat.PNG);

//unregistering all Writers
ImageIOSupport.unregisterWriters(OutputFormat.values());

//unregistering a single Writer
ImageIOSupport.unregisterWriter(OutputFormat.PNG);

You can now run your ImageIO code and see the difference!
