将图像转换为矢量 – C#

using Aspose.Svg.ImageVectorization;
using Aspose.Svg.Saving;
...

// Initialize an instance of the ImageVectorizer class
ImageVectorizer vectorizer = new ImageVectorizer
{
    // Optionally set a configuration
    Configuration =
    {
        // Optionally create an instance of the PathBuilder class
        PathBuilder = new SplinePathBuilder
        {
            TraceSmoother = new ImageTraceSmoother(1),
            TraceSimplifier = new ImageTraceSimplifier(0.3f)
        },
        ColorsLimit = 25,
        LineWidth = 1
    }
};

// Vectorize image from a specified file
using (SVGDocument document = vectorizer.Vectorize(Path.Combine(DataDir, "horses.jpg")))
{
    // Save the vectorized image as SVG
    document.Save(Path.Combine(OutputDir, "horses-new.svg"));
}

将 SVG 合并为 PDF – C#

using Aspose.Svg;
using Aspose.Svg.Rendering;
using Aspose.Svg.Rendering.Pdf;
...

// Initialize SVG documents from files to merge later
using (SVGDocument document1 = new SVGDocument("input1.svg"))
using (SVGDocument document2 = new SVGDocument("input2.svg"))
using (SVGDocument document3 = new SVGDocument("input3.svg"))
{
    // Create an instance of SvgRenderer
    using (SvgRenderer renderer = new SvgRenderer())
    {
        // Create an instance of PdfDevice
        using (PdfDevice device = new PdfDevice("output.pdf"))
        {
            // Merge all SVG documents into a single PDF file
            renderer.Render(device, document1, document2, document3);
        }
    }
