SVG Vectorization and Optimization

• Image Vectorization: Convert raster images like PNG, JPG, BMP into scalable vector graphics using the ImageVectorizer class.
• Text Vectorization: Convert text within SVG into vectorized paths to protect against modifications and ensure high-quality rendering.
• SVG Optimization: Reduce the file size and clean up the SVG by removing unnecessary elements and attributes.

SVG Document Merging and Transformation

• Merge Multiple SVGs: Combine multiple SVG documents into a single file using the Render() method.
• Apply SVG Transformations: Perform transformations like rotation, scaling, and skewing on SVG elements.
• Apply Filters and Gradients: Use SVG filters like Gaussian blur, drop shadow, and more to enhance graphical content.

Environment Configuration

• Custom Configuration: Create and apply custom configuration settings for runtime services, web requests, and more.
• Logging and Message Handlers: Set up logging of network requests and errors using LogMessageHandler.

Advanced SVG Features

• SVG Filters: Apply SVG filters like Gaussian blur and color saturation through code.
• SVG Gradients: Create and apply gradients (linear, radial) within SVG files.
• SVG Transformations: Perform and combine transformations like rotation, scaling, and skewing on SVG elements.
• SVG Text and Fonts: Manipulate text using SVG-specific tags like <text>, <tspan>, and apply glyphs and fonts.

SVG Builder API

• SVGElementBuilder: Create new SVG elements through a fluent API.
• Path Builder: Customize SVG paths programmatically for accurate rendering.
• Paint Builder: Apply stroke and fill attributes to SVG elements efficiently.

Supported File Formats

System Requirements

To build and manipulate SVG documents, the machine running Aspose.SVG for .NET does not require modeling and rendering software installed. Aspose.SVG for .NET includes a document generation engine.

Create Custom SVG Paths Programmatically

Learn how to create SVG paths using the Aspose.SVG for .NET API. Add and customize path elements with attributes for precision in rendering vector graphics.

// Create an SVG path element using Aspose.SVG for .NET
var pathElement = (SVGPathElement)document.CreateElementNS(SvgNamespace, "path");

// Create and configure SVG path segments
SVGPathSeg pathSeg1 = pathElement.CreateSVGPathSegMovetoAbs(10, 200);
SVGPathSeg pathSeg2 = pathElement.CreateSVGPathSegCurvetoQuadraticAbs(180, 200, 25, 210);
SVGPathSeg pathSeg3 = pathElement.CreateSVGPathSegCurvetoQuadraticSmoothAbs(300, 250);
SVGPathSeg pathSeg4 = pathElement.CreateSVGPathSegCurvetoQuadraticSmoothAbs(420, 250);
SVGPathSeg pathSeg5 = pathElement.CreateSVGPathSegCurvetoQuadraticSmoothAbs(490, 150);

// Append segments to the path
pathElement.PathSegList.AppendItem(pathSeg1);
pathElement.PathSegList.AppendItem(pathSeg2);
pathElement.PathSegList.AppendItem(pathSeg3);
pathElement.PathSegList.AppendItem(pathSeg4);
pathElement.PathSegList.AppendItem(pathSeg5);

// Set stroke and fill attributes for the path
pathElement.SetAttribute("stroke", "magenta");
pathElement.SetAttribute("fill", "none");
pathElement.SetAttribute("stroke-width", "4");

// Insert the path element into the SVG document
svgElement.InsertBefore(pathElement, svgElement.FirstChild);

Convert SVG to PNG Easily Using Aspose.SVG for .NET

Quickly convert SVG files to PNG images using the Aspose.SVG for .NET API. A simple solution for rendering high-quality PNGs from SVG documents.

// Load the SVG document from a file
using (var document = new SVGDocument(Path.Combine(DataDir, "owl.svg")))
{
    // Initialize the SvgRenderer to render the document
    using (var renderer = new SvgRenderer())
    {
        // Create an ImageDevice to save the rendered output as PNG
        using (var device = new ImageDevice(Path.Combine(OutputDir, "owl.png")))
        {
            // Render the SVG document to PNG format
            renderer.Render(device, document);
        }
    }
}

Merge Multiple SVG Documents into a Single PDF

Combine multiple SVG files into a single PDF with the Aspose.SVG for .NET API. This guide shows how to render multiple SVG documents into one PDF file.

// Load multiple SVG documents from files
using (var document1 = new SVGDocument(Path.Combine(DataDir, "circle.svg")))
using (var document2 = new SVGDocument(Path.Combine(DataDir, "flower.svg")))
using (var document3 = new SVGDocument(Path.Combine(DataDir, "lineto.svg")))
{
    // Initialize the SvgRenderer for rendering multiple SVGs
    using (var renderer = new SvgRenderer())
    {
        // Create a PdfDevice to save the output as a PDF
        using (var device = new PdfDevice(Path.Combine(OutputDir, "result.pdf")))
        {
            // Render and merge all SVG documents into a single PDF
            renderer.Render(device, document1, document2, document3);
        }
    }
}
