3D and Visual Effects

Darbas su 3D efektais ir vizualiniais efektais — Aspose.Slides FOSS for Java

Aspose.Slides FOSS for Java provides two separate effect systems accessible on every shape:

EffectFormat (shape.getEffectFormat()): 2D vizualiniai efektai: šešėlis, švytėjimas, minkštas kraštas, išsklaida, atspindys
ThreeDFormat (shape.getThreeDFormat()): 3D išvaizda: briaunavimas, kameros projekcija, apšvietimo įranga, medžiaga, išspaudimo gylis

Abu išlieka per išsaugojimo/persikrovimo ciklus.

Vizualiniai efektai (EffectFormat)

Išorinis kritimo šešėlis

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.drawing.Color;
import org.aspose.slides.foss.export.SaveFormat;

try (Presentation prs = new Presentation()) {
    var shape = prs.getSlides().get(0).getShapes().addAutoShape(ShapeType.RECTANGLE, 100, 100, 300, 120);
    shape.addTextFrame("Shadowed Text");

    var ef = shape.getEffectFormat();
    ef.enableOuterShadowEffect();
    ef.getOuterShadowEffect().setBlurRadius(10);      // softness in points
    ef.getOuterShadowEffect().setDirection(315);       // angle: 315 = upper-left cast
    ef.getOuterShadowEffect().setDistance(8);          // offset in points
    ef.getOuterShadowEffect().getShadowColor().setColor(Color.fromArgb(128, 0, 0, 0));  // semi-transparent black

    prs.save("shadow.pptx", SaveFormat.PPTX);
}

Bendra direction reikšmės: 0 = dešinė, 45 = apatinė dešinė, 90 = žemyn, 270 = aukštyn, 315 = viršutinė kairė.

Švytėjimo efektas

import org.aspose.slides.foss.Presentation;

import org.aspose.slides.foss.drawing.Color;
import org.aspose.slides.foss.export.SaveFormat;

try (Presentation prs = new Presentation()) {
    var shape = prs.getSlides().get(0).getShapes().addAutoShape(ShapeType.ELLIPSE, 150, 100, 200, 200);

    var ef = shape.getEffectFormat();
    ef.enableGlowEffect();
    ef.getGlowEffect().setRadius(15);
    ef.getGlowEffect().getColor().setColor(Color.fromArgb(255, 255, 215, 0));  // gold

    prs.save("glow.pptx", SaveFormat.PPTX);
}

Minkšta kraštinė (plaukuota riba)

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.export.SaveFormat;

try (Presentation prs = new Presentation()) {
    var shape = prs.getSlides().get(0).getShapes().addAutoShape(ShapeType.RECTANGLE, 100, 100, 350, 180);

    var ef = shape.getEffectFormat();
    ef.enableSoftEdgeEffect();
    ef.getSoftEdgeEffect().setRadius(12);   // feather radius in points

    prs.save("soft-edge.pptx", SaveFormat.PPTX);
}

Blyksnis

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.export.SaveFormat;

try (Presentation prs = new Presentation()) {
    var shape = prs.getSlides().get(0).getShapes().addAutoShape(ShapeType.RECTANGLE, 100, 100, 350, 180);

    shape.getEffectFormat().setBlurEffect(8, true);

    prs.save("blur.pptx", SaveFormat.PPTX);
}

Efektų tikrinimas ir šalinimas

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ShapeType;

try (Presentation prs = new Presentation()) {
    var shape = prs.getSlides().get(0).getShapes().addAutoShape(ShapeType.RECTANGLE, 100, 100, 200, 100);
    var ef = shape.getEffectFormat();

    ef.enableOuterShadowEffect();
    ef.enableGlowEffect();
    System.out.println("Has effects: " + !ef.isNoEffects());  // true

    ef.disableOuterShadowEffect();
    ef.disableGlowEffect();
    System.out.println("Has effects: " + !ef.isNoEffects());  // false
}

3D Formatting (ThreeDFormat)

    var shape = prs.getSlides().get(0).getShapes().addAutoShape(ShapeType.RECTANGLE, 150, 150, 250, 120);
    shape.addTextFrame("3D Button");

    var tdf = shape.getThreeDFormat();
    tdf.getBevelTop().setBevelType(BevelPresetType.CIRCLE);

    // Solid fill
    shape.getFillFormat().setFillType(FillType.SOLID);
