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 Python code shows you how to apply the outer shadow effect (outer_shadow_effect) to a rectangle:

import aspose.slides as slides
import aspose.pydrawing as draw

with slides.Presentation() as pres:
    shape = pres.slides[0].shapes.add_auto_shape(slides.ShapeType.ROUND_CORNER_RECTANGLE, 20, 20, 200, 150)

    shape.effect_format.enable_outer_shadow_effect()
    shape.effect_format.outer_shadow_effect.shadow_color.color = draw.Color.dark_gray
    shape.effect_format.outer_shadow_effect.distance = 10
    shape.effect_format.outer_shadow_effect.direction = 45

    pres.save("output.pptx", slides.export.SaveFormat.PPTX)

Apply Reflection Effect

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

import aspose.slides as slides
import aspose.pydrawing as draw

with slides.Presentation() as pres:
    shape = pres.slides[0].shapes.add_auto_shape(slides.ShapeType.ROUND_CORNER_RECTANGLE, 20, 20, 200, 150)

    shape.effect_format.enable_reflection_effect()
    shape.effect_format.reflection_effect.rectangle_align = slides.RectangleAlignment.BOTTOM
    shape.effect_format.reflection_effect.direction = 90
    shape.effect_format.reflection_effect.distance = 55
    shape.effect_format.reflection_effect.blur_radius = 4

    pres.save("reflection.pptx", slides.export.SaveFormat.PPTX)

Apply Glow Effect

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

import aspose.slides as slides
import aspose.pydrawing as draw

with slides.Presentation() as pres:
    shape = pres.slides[0].shapes.add_auto_shape(slides.ShapeType.ROUND_CORNER_RECTANGLE, 20, 20, 200, 150)

    shape.effect_format.enable_glow_effect()
    shape.effect_format.glow_effect.color.color = draw.Color.magenta
    shape.effect_format.glow_effect.radius = 15

    pres.save("glow.pptx", slides.export.SaveFormat.PPTX)

Apply Soft Edges Effect

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

import aspose.slides as slides
import aspose.pydrawing as draw

with slides.Presentation() as pres:
    shape = pres.slides[0].shapes.add_auto_shape(slides.ShapeType.ROUND_CORNER_RECTANGLE, 20, 20, 200, 150)

    shape.effect_format.enable_soft_edge_effect()
    shape.effect_format.soft_edge_effect.radius = 15

    pres.save("softEdges.pptx", slides.export.SaveFormat.PPTX)
