Visuelle Effekte in PowerPoint-Präsentationen mit Java | File Format Processing Plugins for C# .NET Core

Aspose.Slides FOSS for Java lets you apply professional-quality visual effects to PowerPoint shapes entirely in Java, with no Microsoft Office and no API keys. This post demonstrates the fill system, 2D effects, and 3D formatting available in the library.

Das Füllsystem

Jede Form hat ein Füllformat, das über getFillFormat() das steuert, wie ihr Inneres gemalt wird. Die fünf Fülltypen decken das gesamte Spektrum der Designpalette von PowerPoint ab.

Einfarbige Füllung

Die einfachste Füllung, eine einheitliche Farbe mit optionaler Transparenz:

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IAutoShape;
import org.aspose.slides.foss.IFillFormat;
import org.aspose.slides.foss.IGradientFormat;
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.GradientShape;
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()) {
    IAutoShape shape = prs.getSlides().get(0).getShapes().addAutoShape(
        ShapeType.ROUND_CORNER_RECTANGLE, 100, 100, 400, 150
    );
    shape.addTextFrame("Solid Fill");

    shape.getFillFormat().setFillType(FillType.SOLID);
    shape.getFillFormat().getSolidFillColor().setColor(new Color(30, 80, 180));

    prs.save("solid.pptx");
}

Linearer Farbverlauf

Verlaufsstopps ermöglichen das Mischen von einer Farbe zur anderen über die Form hinweg:

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IAutoShape;
import org.aspose.slides.foss.IFillFormat;
import org.aspose.slides.foss.IGradientFormat;
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.GradientShape;
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()) {
    IAutoShape shape = prs.getSlides().get(0).getShapes().addAutoShape(
        ShapeType.RECTANGLE, 100, 100, 400, 150
    );

    IFillFormat ff = shape.getFillFormat();
    ff.setFillType(FillType.GRADIENT);
    IGradientFormat gf = ff.getGradientFormat();
    gf.setGradientShape(GradientShape.LINEAR);
    gf.setLinearGradientAngle(90);   // top-to-bottom

    gf.getGradientStops().add(0.0f, new Color(30, 80, 180));   // top: blue
    gf.getGradientStops().add(1.0f, new Color(0, 200, 160));   // bottom: teal

    prs.save("gradient.pptx");
}

2D Visual Effects

Äußerer Drop‑Shadow

Fügen Sie einer beliebigen Form einen halbtransparenten Drop‑Shadow hinzu:

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IAutoShape;
import org.aspose.slides.foss.IFillFormat;
import org.aspose.slides.foss.IGradientFormat;
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.GradientShape;
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()) {
    IAutoShape shape = prs.getSlides().get(0).getShapes().addAutoShape(
        ShapeType.ROUND_CORNER_RECTANGLE, 100, 100, 350, 150
    );
    shape.addTextFrame("Drop Shadow");

    shape.getFillFormat().setFillType(FillType.SOLID);
    shape.getFillFormat().getSolidFillColor().setColor(Color.WHITE);

    IEffectFormat ef = shape.getEffectFormat();
    ef.enableOuterShadowEffect();
    ef.getOuterShadowEffect().setBlurRadius(12);
    ef.getOuterShadowEffect().setDirection(315);   // upper-left
    ef.getOuterShadowEffect().setDistance(8);
    ef.getOuterShadowEffect().getShadowColor().setColor(new Color(100, 0, 0, 0));

    prs.save("shadow.pptx");
}

Leuchteffekt

Ein farbiger Halo um die Formkante:

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IAutoShape;
import org.aspose.slides.foss.IFillFormat;
import org.aspose.slides.foss.IGradientFormat;
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.GradientShape;
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()) {
    IAutoShape shape = prs.getSlides().get(0).getShapes().addAutoShape(
        ShapeType.ELLIPSE, 150, 100, 250, 250
    );
    shape.getFillFormat().setFillType(FillType.SOLID);
    shape.getFillFormat().getSolidFillColor().setColor(new Color(20, 60, 140));

    IEffectFormat ef = shape.getEffectFormat();
    ef.enableGlowEffect();
    ef.getGlowEffect().setRadius(20);
    ef.getGlowEffect().getColor().setColor(new Color(200, 0, 180, 255));

    prs.save("glow.pptx");
}

3D Formatting

Abrundung und Material

Die getThreeDFormat() Methode verleiht jeder flachen Form ein dreidimensionales Aussehen. Kombinieren Sie eine Abschrägung mit einer Kamera‑Voreinstellung und einem Material für das reichste Ergebnis:

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IAutoShape;
import org.aspose.slides.foss.IFillFormat;
import org.aspose.slides.foss.IGradientFormat;
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.GradientShape;
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()) {
    IAutoShape shape = prs.getSlides().get(0).getShapes().addAutoShape(
        ShapeType.RECTANGLE, 150, 150, 300, 130
    );
    shape.addTextFrame("Metal Button");

    // Blue solid fill
    shape.getFillFormat().setFillType(FillType.SOLID);
    shape.getFillFormat().getSolidFillColor().setColor(new Color(20, 70, 160));

    // 3D bevel + camera + light + material
    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("metal-button.pptx");
}

Kombinieren von Effekten auf derselben Form

Schatten und 3D‑Formatierung können auf einer einzigen Form koexistieren und ermöglichen polierte „Karten“-Designs:

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IAutoShape;
import org.aspose.slides.foss.IFillFormat;
import org.aspose.slides.foss.IGradientFormat;
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.GradientShape;
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()) {
    IAutoShape shape = prs.getSlides().get(0).getShapes().addAutoShape(
        ShapeType.ROUND_CORNER_RECTANGLE, 120, 120, 360, 150
    );
    shape.addTextFrame("Premium Card");

    // Fill
    shape.getFillFormat().setFillType(FillType.SOLID);
    shape.getFillFormat().getSolidFillColor().setColor(new Color(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(14);
    ef.getOuterShadowEffect().setDirection(270);
    ef.getOuterShadowEffect().setDistance(8);
    ef.getOuterShadowEffect().getShadowColor().setColor(new Color(70, 0, 0, 0));

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