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.
