## Stroke::get_BackTintAndShade method


Gets or sets a double value that lightens or darkens the stroke background color.

```cpp
double Aspose::Words::Drawing::Stroke::get_BackTintAndShade()
```

## Remarks


The allowed values are within the range from -1 (the darkest) to 1 (the lightest) for this property. Zero (0) is neutral. Attempting to set this property to a value less than -1 or more than 1 results in [ArgumentOutOfRangeException](../).

## Examples

```cpp
auto doc = System::MakeObject<Aspose::Words::Document>(System::String(get_MyDir() + u"Stroke gradient outline.docx"));

auto shape = System::ExplicitCast<Aspose::Words::Drawing::Shape>(doc->GetChild(NodeType::Shape, 0, true));
System::SharedPtr<Aspose::Words::Drawing::Stroke> stroke = shape->get_Stroke();
stroke->set_BackThemeColor(ThemeColor::Dark2);
stroke->set_BackTintAndShade(0.2);

doc->Save(get_ArtifactsDir() + u"Shape.StrokeBackThemeColors.docx");
