تأثيرات البصرية في PowerPoint Presentations with 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 المملوء

كل شكل يحتوي على تنسيق ملء يتوفر من خلال getFillFormat() يسيطر على كيفية رسم الداخلي.تغطي أنواع التعبئة الخمسة مجموعة كاملة من لوحة التصميم في PowerPoint.

ملء صلب

أسهل ملء، 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");
}

خطية Gradient Fill

توقف الجرادين يسمح لك لخلط من لون إلى آخر 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

    );
    shape.addTextFrame("Drop Shadow");

    // 3D bevel
