Esempi

L’esempio di codice seguente mostra il rendering dell’effetto Stroke con Color Fill.

[C#]

// Implementa il rendering dell'effetto Stroke con Color Fill per l'esportazione
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;
    }

    // Salva psd
    im.Save(exportPath, new PsdOptions());
    // Salva png
    im.Save(exportPathPng, new PngOptions()
    {
        ColorType = PngColorType.TruecolorWithAlpha
    });
}

    fillSettings.Color = Color.Yellow;

    colorStroke.Opacity = 127;
    colorStroke.BlendMode = BlendMode.Color;
    im.Save(exportPath);
}

// Prova il file dopo la modifica
using (var im = (PsdImage)Image.Load(exportPath, loadOptions))
