如何在 PSD 文件中绘制和编辑格式,使用 Aspose.PSD 为 .NET

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

string inputFile = "./input/sample_with_shape.psd";
string outputFile = "./output/sample_shape_edited.psd";

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

ShapeLayer shapeLayer = null;
foreach (var layer in psdImage.Layers)
{
    if (layer is ShapeLayer s)
    {
        shapeLayer = s;
        break;
    }
}
if (shapeLayer == null)
{
    throw new InvalidOperationException("No shape layer found in PSD.");
}

// Change fill color
shapeLayer.Fill = new FillLayer(new GradientFillSettings());

// Edit the path (add a new bezier knot for example)
var pathShape = new PathShape();
pathShape.SetItems(
    new BezierKnotRecord[] {
        new BezierKnotRecord() {
            Points = new Point[] {
                new Point(5, 5),
                new Point(25, 45),
                new Point(32, 42) } } }
);
shapeLayer.Path.SetItems(new PathShape[] { pathShape });

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