Title: ecw compressor
Hi Sarah,

The free ECW compressor can be called as a command line utility with parameters. The below sample converts a TIFF to ECW. "10" is the compression factor used, and "rgb" speaks for itself.

"C:\Program Files\Earth Resource Mapping\ECW Compressor 2.6\Bin\ecw_compress_free.exe" maptile.tif -o maptile -c 10 -rgb

Have a look in the online help for more possible parameters.

Best regards / Med venlig hilsen

Hi,

I wondered if anyone could recommend a free application that would enable me to convert jpg files to ecws in bulk.  At the moment I am having to compress one at a time using ER Mapper ECW Compressor 2.2 and it is taking forever - I have 1,877 to do!!

Thanks for your help
