Kesan Visual dalam Pembentangan PowerPoint dengan Java | File Format Processing Plugins for C# .NET Core

Aspose.Slides FOSS untuk Java membolehkan anda menerapkan kesan visual berkualiti profesional pada bentuk PowerPoint sepenuhnya dalam Java, tanpa Microsoft Office dan tanpa kunci API. Kiriman ini menunjukkan sistem pengisian, kesan 2D, dan pemformatan 3D yang tersedia dalam perpustakaan.

Sistem Pengisian

Setiap bentuk mempunyai format isi yang diakses melalui getFillFormat() yang mengawal bagaimana bahagian dalamnya dicat. Lima jenis isi meliputi keseluruhan rangkaian palet reka bentuk PowerPoint.

Isian Pepejal

Isian paling mudah, warna rata dengan kebolehan kelegapan pilihan:

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;

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");
}

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");
}

Kesan Visual 2D

        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();

Pemformatan 3D

Bevel dan Bahan

Kaedah getThreeDFormat() memberikan sebarang bentuk rata penampilan tiga dimensi. Gabungkan bevel dengan preset kamera dan bahan untuk hasil yang paling kaya:

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");
}

Menggabungkan Kesan pada Bentuk yang Sama

Bayang dan pemformatan 3D boleh wujud bersama pada satu bentuk, membolehkan reka bentuk “kad” yang dipoles:

    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");
}
