Como aplicar efeitos e sombras 3D para formas

Este guia mostra como aplicar efeitos visuais 2D e 3D para formas do PowerPoint usando Aspose.Slides FOSS for Java. Use shape.getEffectFormat() para efeitos 2D (sombra externa, brilho, desfoque, borda macia) e shape.getThreeDFormat() Para a aparência 3D (bevel, perspectiva da câmara, plataforma de iluminação, material, profundidade), ambos os sistemas de efeitos podem ser combinados na mesma forma.

Precondições

Adicione a seguinte dependência ao seu pom.xml incluir a biblioteca:

<dependency>
  <groupId>org.aspose</groupId>
  <artifactId>aspose-slides-foss</artifactId>
  <version>26.7.0</version>
</dependency>

Adicionar uma sombra de gota exterior

Ativar uma sombra de queda chamando ef.enableOuterShadowEffect() na forma do IEffectFormat, em seguida, definir raio de desfoque, direção e distância:

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IAutoShape;
import org.aspose.slides.foss.IEffectFormat;
import org.aspose.slides.foss.IThreeDFormat;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.FillType;
import org.aspose.slides.foss.BevelPresetType;
import org.aspose.slides.foss.CameraPresetType;
import org.aspose.slides.foss.LightRigPresetType;
import org.aspose.slides.foss.LightingDirection;
import org.aspose.slides.foss.MaterialPresetType;
import org.aspose.slides.foss.export.SaveFormat;
import org.aspose.slides.foss.drawing.Color;

try (Presentation prs = new Presentation()) {
    ISlideCollection slides = prs.getSlides();
    ISlide slide = slides.get(0);
    IAutoShape shape = slide.getShapes().addAutoShape(
        ShapeType.RECTANGLE, 100, 100, 300, 120
    );
    shape.addTextFrame("Shadowed Shape");

    IEffectFormat ef = shape.getEffectFormat();
    ef.enableOuterShadowEffect();
    ef.getOuterShadowEffect().setBlurRadius(10);       // softness in points
    ef.getOuterShadowEffect().setDirection(315);       // 315 degrees = upper-left
    ef.getOuterShadowEffect().setDistance(8);           // offset in points
    ef.getOuterShadowEffect().getShadowColor().setColor(
        Color.fromArgb(128, 0, 0, 0)
    );

    prs.save("shadow.pptx", SaveFormat.PPTX);
}

Comum direction valores de: 0- Certo, não., 45= inferior-direita, 90= para baixo, 180= à esquerda, 270- Para cima., 315- A esquerda.

Adicionar um efeito de brilho

Ativar um anel de brilho em torno da forma chamando ef.enableGlowEffect(), então configure o raio e a cor:

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IAutoShape;
import org.aspose.slides.foss.IEffectFormat;
import org.aspose.slides.foss.IThreeDFormat;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.FillType;
import org.aspose.slides.foss.BevelPresetType;
import org.aspose.slides.foss.CameraPresetType;
import org.aspose.slides.foss.LightRigPresetType;
import org.aspose.slides.foss.LightingDirection;
import org.aspose.slides.foss.MaterialPresetType;
import org.aspose.slides.foss.export.SaveFormat;
import org.aspose.slides.foss.drawing.Color;

try (Presentation prs = new Presentation()) {
    ISlideCollection slides = prs.getSlides();
    ISlide slide = slides.get(0);
    IAutoShape shape = slide.getShapes().addAutoShape(
        ShapeType.ELLIPSE, 150, 100, 250, 250
    );

    IEffectFormat ef = shape.getEffectFormat();
    ef.enableGlowEffect();
    ef.getGlowEffect().setRadius(20);
    ef.getGlowEffect().getColor().setColor(
        Color.fromArgb(255, 255, 215, 0)   // gold
    );

    prs.save("glow.pptx", SaveFormat.PPTX);
}

Aplicar um desfoque gaussiano

Aplicar um desfoque gaussiano a uma forma chamando shape.getEffectFormat().setBlurEffect(radius, grow):

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IAutoShape;
import org.aspose.slides.foss.IEffectFormat;
import org.aspose.slides.foss.IThreeDFormat;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.FillType;
import org.aspose.slides.foss.BevelPresetType;
import org.aspose.slides.foss.CameraPresetType;
import org.aspose.slides.foss.LightRigPresetType;
import org.aspose.slides.foss.LightingDirection;
import org.aspose.slides.foss.MaterialPresetType;
import org.aspose.slides.foss.export.SaveFormat;
import org.aspose.slides.foss.drawing.Color;

try (Presentation prs = new Presentation()) {
    ISlideCollection slides = prs.getSlides();
    ISlide slide = slides.get(0);
    IAutoShape shape = slide.getShapes().addAutoShape(
        ShapeType.RECTANGLE, 100, 100, 350, 180
    );
    shape.getEffectFormat().setBlurEffect(10, true);

    prs.save("blur.pptx", SaveFormat.PPTX);
}

grow=true expande a região de desfocamento para além do limite da forma; grow=false Clip a mancha dentro da forma.

Aplicar um Bevel 3D

Adicionar um bisel de borda elevada configurando shape.getThreeDFormat().getBevelTop() com um BevelPresetType constante, depois definir a largura e altura:

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IAutoShape;
import org.aspose.slides.foss.IEffectFormat;
import org.aspose.slides.foss.IThreeDFormat;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.FillType;
import org.aspose.slides.foss.BevelPresetType;
import org.aspose.slides.foss.CameraPresetType;
import org.aspose.slides.foss.LightRigPresetType;
import org.aspose.slides.foss.LightingDirection;
import org.aspose.slides.foss.MaterialPresetType;
import org.aspose.slides.foss.export.SaveFormat;
import org.aspose.slides.foss.drawing.Color;

try (Presentation prs = new Presentation()) {
    ISlideCollection slides = prs.getSlides();
    ISlide slide = slides.get(0);
    IAutoShape shape = slide.getShapes().addAutoShape(
        ShapeType.RECTANGLE, 150, 150, 280, 120
    );
    shape.addTextFrame("3D Button");

    IThreeDFormat tdf = shape.getThreeDFormat();
    tdf.getBevelTop().setBevelType(BevelPresetType.CIRCLE);
    tdf.getBevelTop().setWidth(12);
    tdf.getBevelTop().setHeight(6);

    prs.save("bevel.pptx", SaveFormat.PPTX);
}

BevelPresetType valores de: CIRCLE, RELAXED_INSET, COOL_SLANT, DIVOT, RIBLET, HARD_EDGE, SLOPE, CONVEX

3D Bevel with Camera and Light Rig

Combine um bisel com uma projeção de câmera e equipamento de iluminação para produzir uma aparência metálica totalmente tridimensional. tdf.getCamera().setCameraType(), tdf.getLightRig().setLightType(), tdf.getLightRig().setDirection(), e tdf.setMaterial():

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IAutoShape;
import org.aspose.slides.foss.IEffectFormat;
import org.aspose.slides.foss.IThreeDFormat;

import org.aspose.slides.foss.LightingDirection;
import org.aspose.slides.foss.MaterialPresetType;
import org.aspose.slides.foss.export.SaveFormat;
import org.aspose.slides.foss.drawing.Color;

try (Presentation prs = new Presentation()) {
    ISlideCollection slides = prs.getSlides();
    ISlide slide = slides.get(0);
    IAutoShape shape = slide.getShapes().addAutoShape(
        ShapeType.RECTANGLE, 150, 150, 280, 120
    );
    shape.addTextFrame("Metal Button");

    IThreeDFormat tdf = shape.getThreeDFormat();
    tdf.getBevelTop().setBevelType(BevelPresetType.CIRCLE);
    tdf.getBevelTop().setWidth(10);
    tdf.getBevelTop().setHeight(5);
    tdf.getCamera().setCameraType(CameraPresetType.PERSPECTIVE_ABOVE);
    tdf.getLightRig().setLightType(LightRigPresetType.BALANCED);
    tdf.getLightRig().setDirection(LightingDirection.TOP);
    tdf.setMaterial(MaterialPresetType.METAL);
    tdf.setDepth(20);

    prs.save("3d-metal.pptx", SaveFormat.PPTX);
}

Combina sombra e 3D Bevel

Os dois sistemas de efeito podem ser ativados simultaneamente na mesma forma:

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IAutoShape;
import org.aspose.slides.foss.IEffectFormat;
import org.aspose.slides.foss.IThreeDFormat;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.FillType;
import org.aspose.slides.foss.BevelPresetType;
import org.aspose.slides.foss.CameraPresetType;
import org.aspose.slides.foss.LightRigPresetType;
import org.aspose.slides.foss.LightingDirection;
import org.aspose.slides.foss.MaterialPresetType;
import org.aspose.slides.foss.export.SaveFormat;
import org.aspose.slides.foss.drawing.Color;

try (Presentation prs = new Presentation()) {
    ISlideCollection slides = prs.getSlides();
    ISlide slide = slides.get(0);
    IAutoShape shape = slide.getShapes().addAutoShape(
        ShapeType.ROUND_CORNER_RECTANGLE, 150, 150, 320, 130
    );
    shape.addTextFrame("Premium Card");

    // Solid fill
    shape.getFillFormat().setFillType(FillType.SOLID);
    shape.getFillFormat().getSolidFillColor().setColor(
        Color.fromArgb(255, 30, 80, 180)
    );

    // 3D bevel
    IThreeDFormat tdf = shape.getThreeDFormat();
    tdf.getBevelTop().setBevelType(BevelPresetType.CIRCLE);
    tdf.getBevelTop().setWidth(8);
    tdf.getCamera().setCameraType(CameraPresetType.PERSPECTIVE_ABOVE);
    tdf.setMaterial(MaterialPresetType.PLASTIC);

    // Drop shadow
    IEffectFormat ef = shape.getEffectFormat();
    ef.enableOuterShadowEffect();
    ef.getOuterShadowEffect().setBlurRadius(12);
    ef.getOuterShadowEffect().setDirection(270);
    ef.getOuterShadowEffect().setDistance(6);
    ef.getOuterShadowEffect().getShadowColor().setColor(
        Color.fromArgb(80, 0, 0, 0)
    );

    prs.save("premium-card.pptx", SaveFormat.PPTX);
}

Verificar e remover efeitos

Verifique se uma forma tem efeitos ativos usando: IEffectFormat.isNoEffects(), então desativar efeitos individuais com o disableOuterShadowEffect() ou a) disableGlowEffect():

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IAutoShape;
import org.aspose.slides.foss.IEffectFormat;
import org.aspose.slides.foss.IThreeDFormat;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.FillType;
import org.aspose.slides.foss.BevelPresetType;
import org.aspose.slides.foss.CameraPresetType;
import org.aspose.slides.foss.LightRigPresetType;
import org.aspose.slides.foss.LightingDirection;
import org.aspose.slides.foss.MaterialPresetType;
import org.aspose.slides.foss.export.SaveFormat;
import org.aspose.slides.foss.drawing.Color;

try (Presentation prs = new Presentation()) {
    ISlideCollection slides = prs.getSlides();
    ISlide slide = slides.get(0);
    IAutoShape shape = slide.getShapes().addAutoShape(
        ShapeType.RECTANGLE, 100, 100, 200, 100
    );
    IEffectFormat ef = shape.getEffectFormat();

    ef.enableOuterShadowEffect();
    ef.enableGlowEffect();
    System.out.println("Has effects: " + !ef.isNoEffects());  // true

    ef.disableOuterShadowEffect();
    ef.disableGlowEffect();
    System.out.println("Has effects: " + !ef.isNoEffects());  // false
}
