如何在 PSD 中更换智能对象,使用 Aspose.PSD 为 .NET

using Aspose.PSD;
using Aspose.PSD.FileFormats.Psd;
using Aspose.PSD.FileFormats.Psd.Layers.SmartObjects;

string inputFile = "./input/sample_with_smartobject.psd";
string replacementImage = "./input/replacement_logo.png";
string outputFile = "./output/sample_smartobject_replaced.psd";

var loadOptions = new PsdLoadOptions() { LoadEffectsResource = true };
PsdImage psdImage = (PsdImage)Image.Load(inputFile, loadOptions);

SmartObjectLayer smartLayer = null;
foreach (var layer in psdImage.Layers)
{
    if (layer is SmartObjectLayer s)
    {
        smartLayer = s;
        break;
    }
}
if (smartLayer == null)
{
    throw new InvalidOperationException("No smart object layer found in PSD.");
}

// The replacement image can be PNG, JPEG, or another PSD
using (var newImage = (RasterImage)Image.Load(replacementImage))
{
    smartLayer.ReplaceContents(newImage);
}

psdImage.Save(outputFile);
psdImage.Dispose();
