# JPEGLS

(GDAL >= 1.8.0)

This driver is an implementation of a JPEG-LS reader/writer based on the Open Source CharLS library (BSD style license).

The driver can read and write lossless or near-lossless images. Note that it is not aimed at dealing with too big images (unless enough virtual memory is available), since the whole image must be compressed/decompressed in a single operation.

## Creation Options

- INTERLEAVE=PIXEL/LINE/BAND : Data interleaving in compressed stream. Default to BAND.

- LOSS_FACTOR=error_threshold : 0 (the default) means loss-less compression. Any higher value will be the maximum bound for the error.
