C++ (Cpp) AllocateScalars Examples

Example #1

TEST_F(CoordinateTransformableDataObject_test, PersistentCoordsSpec_ImageData)
{
    auto imageDataSet = vtkSmartPointer<vtkImageData>::New();
    imageDataSet->SetExtent(0, 1, 2, 4, 0, 0);
    imageDataSet->AllocateScalars(VTK_FLOAT, 1);
    
    ImageDataObject dataObject("image", *imageDataSet);

    const auto coordsSpec = ReferencedCoordinateSystemSpecification(
        CoordinateSystemType::geographic,
        "testGeoSystem",
        "testMetricSystem",
        "",
        { 100, 200 }, { 0.2, 0.3 });

    dataObject.specifyCoordinateSystem(coordsSpec);

    const auto fileName = QDir(TestEnvironment::testDirPath()).filePath("PersistentCoordsSpec.vti");

    ASSERT_TRUE(Exporter::exportData(dataObject, fileName));
    auto readDataObject = Loader::readFile<CoordinateTransformableDataObject>(fileName);
    ASSERT_TRUE(readDataObject);

    ASSERT_EQ(coordsSpec, readDataObject->coordinateSystem());
}
