Apply Shape Effects in Presentations Using Java

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.

• 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 a Shadow Effect

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

Presentation pres = new Presentation();
try {
    IShape shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.RoundCornerRectangle, 20, 20, 200, 150);

    shape.getEffectFormat().enableOuterShadowEffect();
    shape.getEffectFormat().getOuterShadowEffect().getShadowColor().setColor(Color.DARK_GRAY);
    shape.getEffectFormat().getOuterShadowEffect().setDistance(10);
    shape.getEffectFormat().getOuterShadowEffect().setDirection(45);

    pres.save("output.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

Apply a Reflection Effect

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

Presentation pres = new Presentation();
try {
    IShape shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.RoundCornerRectangle, 20, 20, 200, 150);

    shape.getEffectFormat().enableReflectionEffect();
    shape.getEffectFormat().getReflectionEffect().setRectangleAlign(RectangleAlignment.Bottom);
    shape.getEffectFormat().getReflectionEffect().setDirection(90);
    shape.getEffectFormat().getReflectionEffect().setDistance(55);
    shape.getEffectFormat().getReflectionEffect().setBlurRadius(4);

    pres.save("reflection.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

Apply a Glow Effect

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

Presentation pres = new Presentation();
try {
    IShape shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.RoundCornerRectangle, 20, 20, 200, 150);

    shape.getEffectFormat().enableGlowEffect();
    shape.getEffectFormat().getGlowEffect().getColor().setColor(Color.MAGENTA);
    shape.getEffectFormat().getGlowEffect().setRadius(15);

    pres.save("glow.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

Apply a Soft Edges Effect

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

Presentation pres = new Presentation();
try {
    IShape shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.RoundCornerRectangle, 20, 20, 200, 150);

    shape.getEffectFormat().enableSoftEdgeEffect();
    shape.getEffectFormat().getSoftEdgeEffect().setRadius(15);

    pres.save("softEdges.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

FAQ

Can I apply multiple effects to the same shape?

Yes, you can combine different effects, such as shadow, reflection, and glow, on a single shape to create a more dynamic appearance.

What shapes can I apply effects to?

You can apply effects to various shapes, including autoshapes, charts, tables, pictures, SmartArt objects, OLE objects, and more.

Can I apply effects to grouped shapes?

Yes, you can apply effects to grouped shapes. The effect will apply to the entire group.
