레이어 벡터 마스크

레이어 벡터 마스크 개요

벡터 마스크는 레이어의 내용을 자르는 해상도에 독립적인 경로입니다. 벡터 마스크는 일반적으로 픽셀 기반 도구로 생성된 것보다 정확합니다. 핀 또는 모양 도구를 사용하여 벡터 마스크를 생성합니다.

Aspose.PSD는 벡터 마스크의 렌더링 및 적용을 지원합니다. 벡터 마스크를 편집하는 방법은 벡터 경로를 편집함으로써 이루어집니다.

Aspose.PSD의 벡터 경로

Aspose.PSD에서 벡터 경로에 액세스하려면 VsmsResouce 및 VmskResouce 자원을 통해 제공되며, 이들은 VectorPathDataResource의 하위 클래스입니다.

벡터 경로 편집 방법

벡터 경로 구조

경로를 조작하기 위한 기본 구조는 VectorPathRecord입니다. 그러나 편리성을 위해 다음 솔루션이 제안됩니다.

벡터 경로의 쉬운 편집을 위해 VectorPath 클래스를 사용해야 하며, 이 클래스에는 VectorPathDataResource에서 파생된 자원의 벡터 데이터를 편리하게 편집하는 메서드가 포함되어 있습니다.

VectorPath 유형의 개체를 만들어 시작합니다.

편리를 위해, VectorDataProvider.CreateVectorPathForLayer 정적 메서드를 사용하면 입력 레이어에서 벡터 리소스를 찾아 그를 기반으로 한 VectorPath 개체를 만들 수 있습니다.

모든 편집을 마친 후, 변경된 VectorPath 개체를 VectorDataProvider.UpdateLayerFromVectorPath 정적 메서드를 사용하여 레이어에 적용할 수 있습니다.

// For complete examples and data files, please go to https://github.com/aspose-psd/Aspose.PSD-for-.NET

string fileName = "PathExample.psd";

using (var psdImage = (PsdImage)Image.Load(fileName))
{
    // Choose a layer with vector data that you want to edit.
    Layer layer = psdImage.Layers[1];

    // Now we can use VectorPath instance and manipulate path data.
    VectorPath vectorPath = VectorDataProvider.CreateVectorPathForLayer(layer);

    // Apply changes from 'vectorPath' field to the layer.
    VectorDataProvider.UpdateLayerFromVectorPath(layer, vectorPath);
}

VectorPath 유형에는 PathShape 요소 목록이 포함되어 있으며, 하나 이상의 모양으로 구성된 전체 벡터 이미지를 설명합니다.

각 PathShape은 별도의 베지어 점(점) 세트로 구성된 벡터 도형입니다.

점은 도형을 구성하는 포인트로서 BezierKnot 유형의 객체입니다.

다음 코드 예제에서 도형과 점에 액세스하는 방법을 보여줍니다.

// Accessing a figure and points.
PathShape pathShape = vectorPath.Shapes[0];
BezierKnot firstKnot = pathShape.Points[0];

모양을 만드는 방법

모양을 편집하려면 VectorPath.Shapes 목록에서 기존 모양을 가져오거나 PathShape 인스턴스를 생성하고 해당 목록에 추가하여 새로운 모양을 추가해야 합니다.

// Adds new one shape
vectorPath.Shapes.Add(new PathShape());
// or gets an existing
PathShape pathShape = vectorPath.Shapes[0];

점(포인트)을 추가하는 방법

PathShape.Points 속성을 사용하여 모양의 포인트를 일반 List의 요소로 조작할 수 있으며, 예를 들어 모양 포인트를 추가할 수 있습니다:

// Add new shape with points
PathShape newShape = new PathShape();
newShape.Points.Add(new BezierKnot(new PointF(65, 175), true));
newShape.Points.Add(new BezierKnot(new PointF(65, 210), true));
newShape.Points.Add(new BezierKnot(new PointF(190, 210), true));
newShape.Points.Add(new BezierKnot(new PointF(190, 175), true));
vectorPath.Shapes.Add(newShape);

베지어 점에는 앵커 포인트와 두 개의 제어 포인트가 포함됩니다.

앵커 포인트와 제어 포인트가 동일한 값인 경우 해당 노드는 예각을 가집니다.

Photoshop에서 발생하는 것과 유사하게 앵커 포인트 위치를 변경하려면 BezierKnot에 Shift 메서드가 있습니다.

다음 코드 예제는 전체 베지어 점을 Y 좌표를 통해 수직으로 이동하는 방법을 보여줍니다:

PathShape.Points 속성을 사용하여 모양의 포인트를 일반 List의 요소로 조작할 수 있으며, 예를 들어 모양 포인트를 추가할 수 있습니다:

pathShape.Points[0].Shift(0, 25);

PathShape 속성

PathShape 편집은 노드 편집으로 제한되지 않으며, 이 유형에는 다른 속성도 있습니다.

경로 작업(부울 작업)

PathOperations 속성은 여러 모양이 어떻게 혼합되는지를 정의하는 부울 연산이라고 불립니다.

다음과 같은 가능한 값이 있습니다:

• 0 = 중첩된 모양 제외(XOR 연산).
• 1 = 모양 결합(OR 연산).
• 2 = 앞 모양 뺌(NOT 연산).
• 3 = 모양 영역 교차(AND 연산).

IsClosed 속성

또한 PathShape.IsClosed 속성을 사용하여 모양의 첫 번째와 마지막 점이 연결되었는지를 확인할 수 있습니다.

닫힌 모양	열린 모양

FillColor 속성

어떤 도형도 고유한 색상을 가질 수 있으므로 VectorPath.FillColor 속성을 사용하여 전체 벡터 경로의 색상을 변경할 수 있습니다.

PathShape.Points 속성을 사용하여 모양의 포인트를 일반 List의 요소로 조작할 수 있으며, 예를 들어 모양 포인트를 추가할 수 있습니다:

vectorPath.FillColor = Color.Violet;
