There is the 'ECW JPEG 2000 compressor' FREE tool that should do the trick. Maybe that tool is no longer available.

If not drop me a line and I could sent it to you (note that it is a an.exe file).Is this a conversion or a way of sending large files in a smaller dose? Hans I did think your reply was to be expected. Hence my tongue in cheek remark. What I 've never understood was why Manifold took so long to load my 300+ mb tiffs when I could load them into my survey software and start working long before Manifold had finished loading and that was while Manifold was running in the background. I might just have to pitch in and go through them all and get it over and done with. ECW JPEG 2000 compressor It is a stand alone executable that I believe was made by the original developers of the ECW format.

(Earth Resource Mapping) who made the ER mapper software et al. It can take a geotiff and numerous other formats and convert it to an ecw.

Enhanced compression wavelet. ECW can compress imagery to 5-10% of the original size. (ISO’s standard GML for JPEG 2000). Selection of software according to 'Jpeg 2000 wic codec' topic.

Many thanks all, sorry didn't get back earlier. Its amazing - 225mb tiff to 8mb ecw. (setting of 20 for desired compression ratio) Very quick and I loaded result in Cad and also Manifold and the difference between the tiff and ecw is negligable if any in terms of image quality. Great little tool. Slick Rick Behind Bars Rar there. I installed this on Win 7 Pro 64 bit and it didn't complain or balk. Telcordia Sr 332 Handbook Of North.

The ER Mapper Enhanced Compression Wavelet (ECW) facility enables you to substantially reduce the file sizes of your images without any noticeable deterioration in quality. The ER Mapper ECW Compressor uses wavelet compression technology which offers very good quality results at high compression rates.

You can typically compress a color image to less than 2% to 5% of its original size (50:1 to 20:1 compression ratio) and compress a grayscale image to less than 5% to 10% of its original size (20:1 to 10:1 compression ratio). This means that, at 20:1 compression, 500MB of color imagery will compress down to 25MB. You may actually achieve higher compression rates where your source image has a structure well suited to compression. You may want to check out more software, such as ECW for MapInfo, Files Compressed or ERDAS ER Mapper, which might be to ECW Compressor.
