يوضح مثال الكود التالي تجسيد تأثير Stroke مع Color Fill.

[C#]

// تنفيذ عرض تأثير Stroke باستخدام Color Fill للتصدير
string sourceFileName = "StrokeComplex.psd";
string exportPath = "StrokeComplexRendering.psd";
string exportPathPng = "StrokeComplexRendering.png";
var loadOptions = new PsdLoadOptions()
{
    LoadEffectsResource = true
};
using (var im = (PsdImage)Image.Load(sourceFileName, loadOptions))
{
    for (int i = 0; i < im.Layers.Length; i++)
    {
        var effect = (StrokeEffect)im.Layers[i].BlendingOptions.Effects[0];
        var settings = (ColorFillSettings)effect.FillSettings;
        settings.Color = Color.DeepPink;
    }

    // حفظ مديرية الأمن العام

    // حفظ png
