  Hi Frank,

I am attempting to execute the following test....

(See <<<<<<<< Below)


void RfpTestJpg::testSpecialCharacters()
{
    wprintf (L"Testing: %ls\n\n", L"RfpTestJpg::testSpecialCharacters()");
    FdoPtr<FdoIConnection> connection = CreateConnection();
    connection->SetConnectionString(L"DefaultRasterFileLocation=\"../../TestData/JPG/NBenguela.2004357.aqua.250m  (.!,@#$%^()_+=-`~[]').jpg\"");
    connection->Open();

    FdoICommand* cmd = connection->CreateCommand(FdoCommandType_Select);
    FdoPtr<FdoISelect> cmdSelect = dynamic_cast<FdoISelect*>(cmd);
    cmdSelect->SetFeatureClassName(L"default");
    FdoPtr<FdoIFeatureReader> featureReader = cmdSelect->Execute();

    FdoInt32 count=0;
    while (featureReader->ReadNext())
    {
        FdoStringP name = featureReader->GetString(L"FeatId");
        FdoPtr<FdoIRaster> raster = featureReader->GetRaster(L"Raster");
        FdoInt32 xsize = raster->GetImageXSize();
        FdoInt32 ysize = raster->GetImageYSize();
        CPPUNIT_ASSERT(xsize == 4000);
        CPPUNIT_ASSERT(ysize == 5400); <<<<<<<<<<<<<<<<<<<

	  FdoPtr<FdoRasterDataModel> dataModel = raster->GetDataModel();
        FdoInt32 ppb = dataModel->GetBitsPerPixel();
	  CPPUNIT_ASSERT(ppb == 24);
	  FdoRasterDataModelType dmType = dataModel->GetDataModelType();
	  CPPUNIT_ASSERT(dmType == FdoRasterDataModelType_RGB);

	  FdoInt32 xTileSize = dataModel->GetTileSizeX();
	  FdoInt32 yTileSize = dataModel->GetTileSizeY();
	  CPPUNIT_ASSERT(xTileSize == 4000);
	  CPPUNIT_ASSERT(yTileSize == 5400);



Which calls.....


/// <summary>Gets the data model in use by this raster property.</summary> /// <returns>Returns the current data model.</returns>
FdoRasterDataModel* FdoRfpBandRaster::GetDataModel () {
    _validate();

    if( m_dataModel != NULL )
        return FDO_SAFE_ADDREF(m_dataModel.p);

    FdoPtr<FdoRasterDataModel> dataModel = FdoRasterDataModel::Create();
    FdoPtr<FdoRfpImage> image =m_geoBandRaster->GetImage();

    if( image->m_components == 4 )
        dataModel->SetDataModelType(FdoRasterDataModelType_RGBA);
    else if( image->m_components == 3 )
        dataModel->SetDataModelType(FdoRasterDataModelType_RGB);
    else if( GDALGetRasterColorInterpretation( image->m_redBand ) == GCI_PaletteIndex )
        dataModel->SetDataModelType(FdoRasterDataModelType_Palette);
    else
        dataModel->SetDataModelType(FdoRasterDataModelType_Gray);

    if( image->m_gdalDataType == GDT_Float32 
        || image->m_gdalDataType == GDT_Float64 )
        dataModel->SetDataType( FdoRasterDataType_Float );
    else if( image->m_gdalDataType == GDT_Int16 
             || image->m_gdalDataType == GDT_Int32 )
        dataModel->SetDataType( FdoRasterDataType_Integer );
    else
        dataModel->SetDataType( FdoRasterDataType_UnsignedInteger );

    dataModel->SetBitsPerPixel( image->m_bytesPerPixel * 8 );

    // set organization to pixel
    dataModel->SetOrganization( FdoRasterDataOrganization_Pixel );

    // Typical "web" use produces modest screen sized images.  For these
    // we might as well treat them as one big tile, as this reduces to one
    // big efficient read in GDAL.  A single RasterIO() call.  For big requested
    // images we treat one row as a tile so we never use too much memory.

    // TODO: We really should be using the tilesize provided by the application.
    if( GetImageXSize() * (double) GetImageYSize() > 4000000 )
    {
        dataModel->SetTileSizeX(GetImageXSize());
        dataModel->SetTileSizeY(1); 	<<<<<<<<<<<<<<<<<<<
    }
    else
    {
        dataModel->SetTileSizeX( GetImageXSize() );
        dataModel->SetTileSizeY( GetImageYSize() );
    }

    m_dataModel = dataModel;

    return FDO_SAFE_ADDREF(m_dataModel.p); }


I am expecting the Y Image size to be 5400. Instead, the provider is setting the Y tile size to 1.
