## **Introduction**

While effects in PowerPoint can be used to make a shape stand out, they differ from [fills](/slides/python-java/shape-formatting/#gradient-fill) 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 provides options under **Preset**. The Preset options are essentially combinations of two or more effects known to look good. 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](https://reference.aspose.com/slides/python-java/aspose.slides/effectformat/) class that allow you to apply the same effects to shapes in PowerPoint presentations.

## **Apply a Shadow Effect**

This Python code shows you how to apply the outer shadow effect ([EffectFormat.getOuterShadowEffect](https://reference.aspose.com/slides/python-java/aspose.slides/effectformat/#getOuterShadowEffect)) to a rectangle:

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Presentation, SaveFormat, ShapeType
from java.awt import Color

presentation = Presentation()
try:
    shape = presentation.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)

    presentation.save("output.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

## **Apply a Reflection Effect**

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

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Presentation, RectangleAlignment, SaveFormat, ShapeType

presentation = Presentation()
try:
    shape = presentation.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)

    presentation.save("reflection.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

## **Apply a Glow Effect**

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

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Presentation, SaveFormat, ShapeType
from java.awt import Color

presentation = Presentation()
try:
    shape = presentation.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)

    presentation.save("glow.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

## **Apply a Soft Edges Effect**

This Python code shows you how to apply a soft edges effect to a shape:

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Presentation, SaveFormat, ShapeType

presentation = Presentation()
try:
    shape = presentation.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.RoundCornerRectangle, 20, 20, 200, 150)

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

    presentation.save("softEdges.pptx", SaveFormat.Pptx)
finally:
    presentation.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.
