Exemples
L’exemple de code suivant montre le rendu de l’effet Stroke avec Color Fill.
[C#]
// Implémenter le rendu de l'effet Stroke avec Color Fill pour l'exportation
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;
}
// Enregistrer le psd
im.Save(exportPath, new PsdOptions());
// Enregistrer png
im.Save(exportPathPng, new PngOptions()
{
ColorType = PngColorType.TruecolorWithAlpha
});
}
