Hi all,

I was some data which I acquired using TIFF files. I was wondering if there is a way to perform JPEG-LS compression and save them to file.

Thanks, Kalyan

OpenCV uses libjpeg as jpeg writing back-end. As I know libjpeg does not support JPEG-LS, because it is not free. Use png format for saving loose-less images.

Thanks for quick response. I appreciate it. Can you please refer me to document which explains about the compression formats are supported by OpenCV?

The most common information about images i/o you can find in official documentation for imread and imwrite function. If you need more information you need to investigate libjpeg, libpng, libtiff, etc documentation and source code of OpenCV highgui module.
