التأثيرات البصرية في عروض PowerPoint التقديمية باستخدام 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.

نظام التعبئة

كل شكل له تنسيق تعبئة يمكن الوصول إليه عبر getFillFormat() الذي يتحكم في كيفية طلاء داخله. تغطي الأنواع الخمسة للتعبئة كامل نطاق لوحة تصميم PowerPoint.

تعبئة صلبة

أبسط تعبئة، لون مسطح مع شفافية اختيارية:

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");
}

تعبئة تدرج خطي

نقاط التدرج تتيح لك دمج لون بآخر عبر الشكل:

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

ظل إسقاط خارجي

إرفاق ظل إسقاط شبه شفاف بأي شكل:

        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");
}

تأثير التوهج

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

3D Formatting

حد ثلاثي الأبعاد ومادة

ال getThreeDFormat() الطريقة تعطي أي شكل مسطح مظهرًا ثلاثي الأبعاد. اجمع بين الحافة وإعداد مسبق للكاميرا ومادة للحصول على أغنى نتيجة:

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");
}

دمج التأثيرات على الشكل نفسه

يمكن لتنسيق الظل وتنسيق ثلاثي الأبعاد أن يتعايشا على شكل واحد، مما يتيح تصاميم “بطاقة” مصقولة:

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.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");
}
