Hi,

Can you send me an ossim-info -d <your-tiff> and I'll take a look.

Thanks,
Dave

Subject: [OSSIM] ossimTiffTileSource class and GeoTiff with complex pixel       values

Dear Ossim developpers,

For the Orfeo Toolbox project, we open with GDAL GeoTiff with complex
pixel values but when we load metadata ossimTiffTileSource::open()
method return false output and a warning message "Cannot determine
scalar type" and dump the trace.

If I well understand the code linked to this warning, ossim didn't
manage tiff file with complex values. Is it normal ?

However OSSIM_CINT16, OSSIM_CINT32, OSSIM_CFLOAT32, OSSIM_CFLOAT64 are
defined as valid ossimScalarType.

This is why I have add some code to my source to overpass this warning
and defined correctly theBytesPerPixel and theScalarType in case of
complex data but a crash appears later.

So I need help to understand why tiff file with complex pixel values are
not managed by Ossim and how to overcome this limitation with a small
patch: avoid trace dump and message warning and provide right metadata.

Best Regards
Savinaud Mickaël
