Работа с 3D ефекти и визуални ефекти — Aspose.Slides FOSS for Java

Aspose.Slides FOSS for Java предоставя две отделни системи за ефекти, достъпни за всяка форма:

  • EffectFormat (shape.getEffectFormat()): 2D визуални ефекти: сянка, сияние, мек ръб, размазване, отражение
  • ThreeDFormat (shape.getThreeDFormat()): 3D външен вид: фаска, проекция на камера, осветителна система, материал, дълбочина на екструзия

И двете се запазват през цикли на запазване/презареждане.

Визуални ефекти (EffectFormat)

Външна падаща сянка 

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);
}

Общи direction стойности: 0 = дясно, 45 = долно-дясно, 90 = надолу, 270 = нагоре, 315 = горно-ляво.

Сияен ефект 

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.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);
}

Мек ръб (перообразна граница) 

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);
}

Размъгване 

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);
}

Проверка и премахване на ефекти 

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 Форматиране (ThreeDFormat)

Ефект на фаска 

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

try (Presentation prs = new Presentation()) {
    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);
    tdf.getBevelTop().setWidth(12);
    tdf.getBevelTop().setHeight(6);

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

Комбиниране на 2D и 3D ефекти

Можете да приложите както getEffectFormat(), така и getThreeDFormat() към една и съща форма:

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.FillType;
import org.aspose.slides.foss.BevelPresetType;
import org.aspose.slides.foss.CameraPresetType;
import org.aspose.slides.foss.MaterialPresetType;
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.ROUND_CORNER_RECTANGLE, 150, 150, 300, 120);
    shape.addTextFrame("Premium Card");

    // Solid fill
    shape.getFillFormat().setFillType(FillType.SOLID);
    shape.getFillFormat().getSolidFillColor().setColor(Color.fromArgb(255, 30, 80, 180));

    // 3D bevel
    var tdf = shape.getThreeDFormat();
    tdf.getBevelTop().setBevelType(BevelPresetType.CIRCLE);
    tdf.getBevelTop().setWidth(8);
    tdf.getCamera().setCameraType(CameraPresetType.PERSPECTIVE_ABOVE);
    tdf.setMaterial(MaterialPresetType.PLASTIC);

    // Drop shadow
    var ef = shape.getEffectFormat();
    ef.enableOuterShadowEffect();
    ef.getOuterShadowEffect().setBlurRadius(12);
    ef.getOuterShadowEffect().setDirection(270);
    ef.getOuterShadowEffect().setDistance(6);
    ef.getOuterShadowEffect().getShadowColor().setColor(Color.fromArgb(80, 0, 0, 0));

    prs.save("premium-card.pptx", SaveFormat.PPTX);
}
