[osg-users] Display Geotiff image in OSG

[Robert Osfield]

Hi Uma,

The tiff plugin uses libtiff 3rd party library that doesn't support
geotiff.  The OSG's gdal plugin does support geotiff but isn't loaded
by default as the .tif extension will be mapped to the tiff plugin.

To get the OSG to use the gdal plugin add a .gdal to the image
filename, the gdal plugin will then strip this and then load the image
i.e.

  osgviewer --image myfile.tif.gdal

Robert.
