3D and Visual Effects

3D 효과 및 시각 효과 작업 — Aspose.Slides FOSS for .NET

Aspose.Slides FOSS for .NET은 모든 도형에서 액세스할 수 있는 두 개의 별도 효과 시스템을 제공합니다:

EffectFormat (shape.EffectFormat): 2D 시각 효과: 그림자, 글로우, 부드러운 가장자리, 블러, 반사
ThreeDFormat (shape.ThreeDFormat): 3D 외관: 베벨, 카메라 투영, 라이트 릭, 재질, 압출 깊이

두 경우 모두 저장/재로드 사이클에서 지속됩니다.

시각 효과 (EffectFormat)

외부 그림자

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);

공통 Direction 값: 0 = 오른쪽, 45 = 오른쪽 아래, 90 = 아래, 270 = 위, 315 = 왼쪽 위.

글로우 효과

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.Ellipse, 150, 100, 200, 200);

var ef = shape.EffectFormat;
ef.EnableGlowEffect();
ef.GlowEffect.Radius = 15;
ef.GlowEffect.Color.Color = Color.Gold;

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

소프트 엣지 (페더링 테두리)

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);

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

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

블러

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);

효과 확인 및 제거

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

3D 서식 (ThreeDFormat)

베벨 효과

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

using var prs = new Presentation();
var shape = prs.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle, 150, 150, 250, 120);
shape.AddTextFrame("3D Button");

var tdf = shape.ThreeDFormat;
tdf.BevelTop.BevelType = BevelPresetType.Circle;
tdf.BevelTop.Width = 12;
tdf.BevelTop.Height = 6;

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

BevelPresetType 값: Circle, RelaxedInset, CoolSlant, Divot, Riblet, HardEdge, Slope, Convex

카메라 프리셋

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

using var prs = new Presentation();
var shape = prs.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle, 150, 150, 250, 120);
var tdf = shape.ThreeDFormat;
tdf.BevelTop.BevelType = BevelPresetType.Circle;
tdf.BevelTop.Width = 10;
tdf.Camera.CameraType = CameraPresetType.PerspectiveAbove;
prs.Save("camera.pptx", SaveFormat.Pptx);

라이트 리그 및 재질

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

using var prs = new Presentation();
var shape = prs.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle, 150, 150, 250, 120);
shape.AddTextFrame("Metal Button");

var tdf = shape.ThreeDFormat;
tdf.BevelTop.BevelType = BevelPresetType.Circle;
tdf.BevelTop.Width = 10;
tdf.BevelTop.Height = 5;
tdf.Camera.CameraType = CameraPresetType.PerspectiveAbove;
tdf.LightRig.LightType = LightRigPresetType.Balanced;
tdf.LightRig.Direction = LightingDirection.Top;
tdf.Material = MaterialPresetType.Metal;
tdf.Depth = 20;

prs.Save("3d-metal.pptx", SaveFormat.Pptx);

MaterialPresetType 값: Standard, Warm, Cool, Plastic, Metal, Matte, WireFrame

2D 및 3D 효과 결합

같은 도형에 EffectFormat와 ThreeDFormat를 모두 적용할 수 있습니다:

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);
