Java HEIC Writer

JDeli includes a HEIC Writer to write HEIC files in Java. The HEIC Encoder is written in 100% Java with no dependencies.

Key information:

• 100% Java solution. No dlls or dependencies on native code easy to use

Quick start or to replace in existing code using ImageIO:

JDeli.write(myBufferedImage, "heic", outputStreamOrFile);

or

byte[] outputData = JDeli.write(myBufferedImage, "heic");

New method for quick and simple usage

JDeli.write(myBufferedImage, OutputFormat.HEIC, outputStreamOrFile)

OutputFormat allows setting of any supported Image Format

For complete control of output:

final HeicEncoderOptions options = new HeicEncoderOptions();


//write out
JDeli.write(myBufferedImage, options, outputStreamOrFile);

HeicEncoderOptions allows setting of specific options.

Various image processing operations can be conducted on the image, detailed documentation can be found here.

Performance comparisons:

These figures were generated using jmh (as documented on our blog) with a standard set of images (also documented). They should be easy to replicate if you wish to validate, the code is on GitHub.

The higher the number, the better.
