We have some IMGs that we're trying to convert to ECWs with the fourth band activated to mask the wretched black null data borders. The instructions we got from ERDAS were to create an AOI and export the data from IMG to ECW using the AOI as the mask layer. However, we keep getting the same error of "ERROR: Could not open ECW Compression Engine" when we try to run that export.
Anyone run into these problems before? The files in question are quite large as IMGs (100+ GBs).
Appreciate any help or advice you may have to offer. Unfortunately, I am limited to this software and this procedure because it is the only one that works with our IMS.
