I am trying to convert some ECW files to PNG using the command gdal_translate test.ecw -of png test.png, but the PNG file comes out grayscale.
How do I produce a colored PNG from an ECW file using this tool?
Output from gdalinfo test.ecw:
Driver: ECW/ERDAS Compressed Wavelets (SDK 3.x)
Files: test.ecw
