Java ile PowerPoint Sunumlarında Görsel Efektler | File Format Processing Plugins for C# .NET Core

Aspose.Slides FOSS for Java, Microsoft Office ve API keys olmadan, tamamen Java içinde PowerPoint şekillerine profesyonel kalitede görsel efektler uygulamanızı sağlar. Bu gönderi, kütüphanede bulunan doldurma sistemi, 2D efektler ve 3D biçimlendirmeyi gösterir.

Doldurma Sistemi

Her şeklin, iç kısmının nasıl boyandığını kontrol eden bir doldurma biçimi vardır ve bu, getFillFormat() aracılığıyla erişilir. Beş doldurma türü, PowerPoint’in tasarım paletinin tam yelpazesini kapsar.

Katı Dolgu

En basit dolgu, isteğe bağlı şeffaflıkla düz bir renk:

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");
}

Doğrusal Degrade Doldurma

Renk geçiş durakları, şekil boyunca bir renkten diğerine karıştırmanıza olanak tanır:

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 Görsel Efektler

Dış Düşen Gölge

Herhangi bir şekle yarı saydam bir gölge ekleyin:

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");
}

        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 Biçimlendirme

Köşe Yuvarlama ve Malzeme

getThreeDFormat() yöntemi, herhangi bir düz şekle üç boyutlu bir görünüm kazandırır. En zengin sonuç için bir bevel’i bir kamera preset’i ve bir malzeme ile birleştirin:

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");
}

Aynı Şekilde Etkileri Birleştirme

Gölge ve 3D biçimlendirme tek bir şekil üzerinde bir arada bulunabilir, bu da cilalı “kart” tasarımlarını mümkün kılar:

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");
}
