GTiff Driver CreateCopy method creates an all black geotiff

[jbeiko]

(I used the GDAL files from: ​http://download.osgeo.org/gdal/win32/1.5/)

In my application, I call CreateCopy(...) from the GTiff driver (using a geotiff file, so yes, I'm 'converting' from geotiff to geotiff) and the result is a geotiff that is properly sized and georeferenced, but is all black.

If I use the include/lib/DLLs from FWTools, the file that is created is correct, and is coloured correctly; so this operation works properly in FWTools.

Below is the output from tiffinfo, gdalinfo, and my source code.
