ECW Images Plot Black from GeoMedia Layout

Symptoms

ECW (other raster formats as well) images plot black from the Layout Window.

Diagnosis

GeoMedia currently has a problem plotting 4 band ECW (and other 4 band format) images  (CR-Defect 1-ANAB3S).  This is a common format, with the 4 bands being visible blue, visible green, visible red and near infrared parts of the spectrum.  Other 4 band image formats also have this problem.

Solution

The workaround is to convert the 4 band ECW to another format, usually just 3 bands; RGB TIFF format would work well.  This conversion can be done by Image Station Raster Utilities, downloadable from this website, or by many third party tools.
