例子

此示例演示了使用不同类型的填充（如颜色、渐变或图案）添加描边效果的能力。

[C#]

using (var psdImage = (PsdImage)Image.Load(srcFile, new PsdLoadOptions() { LoadEffectsResource = true }))
{
    StrokeEffect strokeEffect;

    // 8. 在外部位置添加图案填充

    strokeEffect.Size = 10;
    strokeEffect.Position = StrokePosition.Outside;
    patternFillSettings = strokeEffect.FillSettings as IPatternFillSettings;
    patternFillSettings.Scale = 100;

    // 9. 在中心位置添加图案填充
    strokeEffect = psdImage.Layers[9].BlendingOptions.AddStroke(FillType.Pattern);
    strokeEffect.Size = 10;
    strokeEffect.Position = StrokePosition.Center;

    patternFillSettings.Scale = 75;

    psdImage.Save(outputFilePng, new PngOptions());
