姓名描述

例子

以下代码演示了调整包含矢量路径的形状图层大小的能力。

[C#]

string sourceFileName = "vectorShapes.psd";
string outputFileName = "out_vectorShapes.psd";
string sourcePath = sourceFileName;
string outputPath = outputFileName;
string outputPathPng = Path.ChangeExtension(outputPath, ".png");
using (var psdImage = (PsdImage)Image.Load(sourcePath))
{
    foreach (var layer in psdImage.Layers)
    {
        layer.Resize(layer.Width * 5 / 4, layer.Height / 2);
    }

    psdImage.Save(outputPath);
    psdImage.Save(outputPathPng, new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha });
}

此示例说明如何在 PSD 文件中的 FillLayer 的 Vogk 资源中获取和设置 ShapeOriginSettings 的新 Transform 和 OriginBoxCorners 属性。
