3D and Visual Effects

Lucrul cu efecte 3D și efecte vizuale — Aspose.Slides FOSS pentru .NET

Aspose.Slides FOSS for .NET oferă două sisteme de efecte separate accesibile pe fiecare formă:

EffectFormat (shape.EffectFormat): efecte vizuale 2D: umbră, strălucire, muchie moale, estompare, reflexie
ThreeDFormat (shape.ThreeDFormat): aspect 3D: teșitură, proiecție de cameră, sistem de iluminare, material, adâncime de extrudare

Ambele persistă prin ciclurile de salvare/reîncărcare.

Efecte vizuale (EffectFormat)

Umbră exterioară

using Aspose.Slides.Foss;
using Aspose.Slides.Foss.Drawing;
using Aspose.Slides.Foss.Export;

using var prs = new Presentation();
var shape = prs.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle, 100, 100, 300, 120);
shape.AddTextFrame("Shadowed Text");

var ef = shape.EffectFormat;
ef.EnableOuterShadowEffect();
ef.OuterShadowEffect.BlurRadius = 10;      // softness in points
ef.OuterShadowEffect.Direction = 315;       // angle: 315 = upper-left cast
ef.OuterShadowEffect.Distance = 8;          // offset in points
ef.OuterShadowEffect.ShadowColor.Color = Color.FromArgb(128, 0, 0, 0);  // semi-transparent black

prs.Save("shadow.pptx", SaveFormat.Pptx);

Valorile comune Direction: 0 = dreapta, 45 = dreapta-jos, 90 = jos, 270 = sus, 315 = stânga-sus.

using Aspose.Slides.Foss.Export;

using var prs = new Presentation();
var shape = prs.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle, 100, 100, 350, 180);

var ef = shape.EffectFormat;
ef.EnableSoftEdgeEffect();
ef.SoftEdgeEffect.Radius = 12;   // feather radius in points

prs.Save("soft-edge.pptx", SaveFormat.Pptx);

Estompare

using Aspose.Slides.Foss;
using Aspose.Slides.Foss.Export;

using var prs = new Presentation();
var shape = prs.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle, 100, 100, 350, 180);

shape.EffectFormat.SetBlurEffect(8, true);

prs.Save("blur.pptx", SaveFormat.Pptx);

Verificarea și eliminarea efectelor

using Aspose.Slides.Foss;

using var prs = new Presentation();
var shape = prs.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle, 100, 100, 200, 100);
var ef = shape.EffectFormat;

ef.EnableOuterShadowEffect();
ef.EnableGlowEffect();
Console.WriteLine($"Has effects: {!ef.IsNoEffects}");  // True

ef.DisableOuterShadowEffect();
ef.DisableGlowEffect();
Console.WriteLine($"Has effects: {!ef.IsNoEffects}");  // False

Formatare 3D (ThreeDFormat)

Efect de bisel

using Aspose.Slides.Foss;
using Aspose.Slides.Foss.Export;

var tdf = shape.ThreeDFormat;
tdf.BevelTop.BevelType = BevelPresetType.Circle;

Combinarea efectelor 2D și 3D

Poți aplica ambele EffectFormat și ThreeDFormat pe aceeași formă:

using Aspose.Slides.Foss;
using Aspose.Slides.Foss.Drawing;
using Aspose.Slides.Foss.Export;

using var prs = new Presentation();
var shape = prs.Slides[0].Shapes.AddAutoShape(ShapeType.RoundCornerRectangle, 150, 150, 300, 120);
shape.AddTextFrame("Premium Card");

// Solid fill
shape.FillFormat.FillType = FillType.Solid;
shape.FillFormat.SolidFillColor.Color = Color.FromArgb(255, 30, 80, 180);

// 3D bevel
var tdf = shape.ThreeDFormat;
tdf.BevelTop.BevelType = BevelPresetType.Circle;
tdf.BevelTop.Width = 8;
tdf.Camera.CameraType = CameraPresetType.PerspectiveAbove;
tdf.Material = MaterialPresetType.Plastic;

// Drop shadow
var ef = shape.EffectFormat;
ef.EnableOuterShadowEffect();
ef.OuterShadowEffect.BlurRadius = 12;
ef.OuterShadowEffect.Direction = 270;
ef.OuterShadowEffect.Distance = 6;
ef.OuterShadowEffect.ShadowColor.Color = Color.FromArgb(80, 0, 0, 0);

prs.Save("premium-card.pptx", SaveFormat.Pptx);
