Vizuálne efekty v prezentáciách PowerPoint s 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.

Systém výplní

Každý tvar má formát výplne, ktorý je prístupný cez getFillFormat() ktorý riadi, ako je jeho vnútro maľované. Päť typov výplní pokrýva celý rozsah dizajnového palety PowerPointu.

Plná výplň

Najjednoduchšia výplň, plochá farba s voliteľnou priehľadnosťou:

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");
}

Lineárna gradientová výplň

Zastávky gradientu vám umožňujú prechádzať z jednej farby do druhej po celom tvare:

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

Vonkajší vrhací tieň

Pripojte polopriehľadný vrhací tieň k akémukoľvek tvaru:

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");
}

Efekt žiary

Farebná aura okolo okraja tvaru:

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

Skosenie a materiál

Metóda getThreeDFormat() dáva akémukoľvek plochému tvaru trojrozmerný vzhľad. Spojte sklon s predvoľbou kamery a materiálom pre najbohatší výsledok:

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");
}

Kombinovanie efektov na rovnakom tvare

Tieň a 3D formátovanie môžu koexistovať na jednom tvare, čo umožňuje vylepšené “card” dizajny:

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");
}
