Shape Effect

While effects in PowerPoint can be used to make a shape stand out, they differ from fills or outlines. Using PowerPoint effects, you can create convincing reflections on a shape, spread a shape’s glow, etc.

shape-effect

  • PowerPoint provides six effects that can be applied to shapes. You can apply one or more effects to a shape.

  • Some combinations of effects look better than others. For this reason, PowerPoint options under Preset. The Preset options are essentially a known good-looking combination of two or more effects. This way, by selecting a preset, you won’t have to waste time testing or combining different effects to find a nice combination.

Aspose.Slides provides properties and methods under the EffectFormat class that allow you to apply the same effects to shapes in PowerPoint presentations.

Apply Shadow Effect

This C++ code shows you how to apply the outer shadow effect (OuterShadowEffect) to a rectangle:

auto pres = System::MakeObject<Presentation>();
auto slide = pres->get_Slides()->idx_get(0);
auto shape = slide->get_Shapes()->AddAutoShape(ShapeType::RoundCornerRectangle, 20.0f, 20.0f, 200.0f, 150.0f);

auto effectFormat = shape->get_EffectFormat();
effectFormat->EnableOuterShadowEffect();
auto outerShadowEffect = effectFormat->get_OuterShadowEffect();
outerShadowEffect->get_ShadowColor()->set_Color(System::Drawing::Color::get_DarkGray());
outerShadowEffect->set_Distance(10);
outerShadowEffect->set_Direction(45.0f);

pres->Save(u"output.pptx", SaveFormat::Pptx);

Apply Reflection Effect

This C++ code shows you how to apply the reflection effect to a shape:

auto pres = System::MakeObject<Presentation>();
auto slide = pres->get_Slides()->idx_get(0);
auto shape = slide->get_Shapes()->AddAutoShape(ShapeType::RoundCornerRectangle, 20.0f, 20.0f, 200.0f, 150.0f);

auto effectFormat = shape->get_EffectFormat();
effectFormat->EnableReflectionEffect();
auto reflectionEffect = effectFormat->get_ReflectionEffect();
reflectionEffect->set_RectangleAlign(RectangleAlignment::Bottom);
reflectionEffect->set_Direction(90.0f);
reflectionEffect->set_Distance(55);
reflectionEffect->set_BlurRadius(4);

pres->Save(u"reflection.pptx", SaveFormat::Pptx);

Apply Glow Effect

This C++ code shows you how to apply the glow effect to a shape:

auto pres = System::MakeObject<Presentation>();
auto slide = pres->get_Slides()->idx_get(0);
auto shape = slide->get_Shapes()->AddAutoShape(ShapeType::RoundCornerRectangle, 20.0f, 20.0f, 200.0f, 150.0f);

auto effectFormat = shape->get_EffectFormat();
effectFormat->EnableGlowEffect();
auto glowEffect = effectFormat->get_GlowEffect();
glowEffect->get_Color()->set_Color(System::Drawing::Color::get_Magenta());
glowEffect->set_Radius(15);

pres->Save(u"glow.pptx", SaveFormat::Pptx);

Apply Soft Edges Effect

This C++ code shows you how to apply the soft edges to a shape:

auto pres = System::MakeObject<Presentation>();
auto slide = pres->get_Slides()->idx_get(0);
auto shape = slide->get_Shapes()->AddAutoShape(ShapeType::RoundCornerRectangle, 20.0f, 20.0f, 200.0f, 150.0f);

auto effectFormat = shape->get_EffectFormat();
effectFormat->EnableSoftEdgeEffect();
auto softEdgeEffect = effectFormat->get_SoftEdgeEffect();
softEdgeEffect->set_Radius(15);

pres->Save(u"softEdges.pptx", SaveFormat::Pptx);
