PsdImage.AddShapeLayer

PsdImage.AddShapeLayer method

Add empty Shape layer. Without paths. They should be added to shape layer before save.

public ShapeLayer AddShapeLayer()

Return Value

ShapeLayer instance.

Examples

The following code demonstrates how to add ShapeLayer.

[C#]

    newShapes.Add(newShape);
    layer.Path.SetItems(newShapes.ToArray());

    layer.Update();

    newPsd.Save(outputFile);
}

using (PsdImage image = (PsdImage)Image.Load(outputFile))
{
    AssertAreEqual(2, image.Layers.Length);

    AssertAreEqual(1, shapeLayer.Path.GetItems().Length); // 1 Shape
    AssertAreEqual(3, shapeLayer.Path.GetItems()[0].GetItems().Length); // 3 knots in a shape

    AssertAreEqual(-16127182, internalFill.Color.ToArgb()); // ff09eb32
