JPEGLosslessDecoderJS

A common DICOM compression format is JPEG Lossless. This format is generally not supported in standard JPEG decoder libraries.

This decoder can read data from the following DICOM transfer syntaxes:

1.2.840.10008.1.2.4.57 JPEG Lossless, Nonhierarchical (Processes 14)
1.2.840.10008.1.2.4.70 JPEG Lossless, Nonhierarchical (Processes 14 [Selection 1])

Usage

API and more examples

1var decoder = new jpeg.lossless.Decoder();
2var output = decoder.decompress(buffer [, offset [, length]]);
3
4// Parameters
5// {ArrayBuffer} buffer
6// {Number} offset offset into buffer (default = 0)
7// {Number} length length of buffer (default = end of JPEG block)
8
9// Returns
10// {ArrayBuffer} output (size = cols * rows * bytesPerComponent * numComponents)

Install

Get a packaged source file from the release folder:

Or install via NPM:

npm install jpeg-lossless-decoder-js

Testing

npm test

Building

npm run build

This will output lossless.js and lossless-min.js alongside declaration files and source maps to /release.

Acknowledgments

This decoder was originally written by Helmut Dersch for Java. I added support for selection values 2 through 7, contributed bug fixes and ported to JavaScript.

Also thanks to @jens-ox for modernizing this package to TypeScript.
