ECW COMPRESSION ERROR

I was trying to access articles on the jpeg/ecw compressor.  I'm saving out a large algorithm from ERMapper and I am getting an error message saying,

 

Ecw_compress_gui

Maximum Compression Memory Cache Limit 1.5GB is too low, please set above 1.7GB

 

How do I increase this? Thanks

Re: ECW COMPRESSION ERROR

Hi Richard,

 

The "Maximum Compression Memory Cache Limit " for ER Mapper  can be changed in your Windows "Environment Variable" dialog. 

 

Please go the "Control Panel" > "System" > "Advanced System Settings" > "Advanced tab > "Environment Variable" > Look for the Variable name "ERM_ECWJP2_CACHE_MAXMEM" and edit that value to higher value, say more than 3.5 GB etc.

 

I hope this helps.

 

Regards

Partha Roy
