Examples

This example shows how to load a WMF image from a file and convert it to SVG using WmfRasterizationOptions.

[C#]

string dir = "c:\\temp\\";

// Using Aspose.Imaging.Image.Load is a unified way to load all types of images including WMF.
using (Aspose.Imaging.FileFormats.Wmf.WmfImage wmfImage = (Aspose.Imaging.FileFormats.Wmf.WmfImage)Aspose.Imaging.Image.Load(dir + "test.wmf"))
{
    Aspose.Imaging.ImageOptions.SvgOptions saveOptions = new Aspose.Imaging.ImageOptions.SvgOptions();
        
    // Text will be converted to shapes.
    saveOptions.TextAsShapes = true;

    Aspose.Imaging.ImageOptions.WmfRasterizationOptions rasterizationOptions = new Aspose.Imaging.ImageOptions.WmfRasterizationOptions();

    // The background color of the drawing surface.
    rasterizationOptions.BackgroundColor = Aspose.Imaging.Color.WhiteSmoke;

    // The page size.
    rasterizationOptions.PageSize = wmfImage.Size;

    // If embedded emf exists, then render emf; otherwise render wmf.
    rasterizationOptions.RenderMode = Aspose.Imaging.FileFormats.Wmf.WmfRenderMode.Auto;

    saveOptions.VectorRasterizationOptions = rasterizationOptions;

    wmfImage.Save(dir + "test.output.svg", saveOptions);
}

This example shows how to load a EMF image from a file and convert it to SVG using EmfRasterizationOptions.

[C#]

string dir = "c:\\temp\\";

// Using Aspose.Imaging.Image.Load is a unified way to load all types of images including EMF.
using (Aspose.Imaging.FileFormats.Emf.EmfImage emfImage = (Aspose.Imaging.FileFormats.Emf.EmfImage)Aspose.Imaging.Image.Load(dir + "test.emf"))
{
    Aspose.Imaging.ImageOptions.SvgOptions saveOptions = new Aspose.Imaging.ImageOptions.SvgOptions();

    // Text will be converted to shapes.
    saveOptions.TextAsShapes = true;

    Aspose.Imaging.ImageOptions.EmfRasterizationOptions rasterizationOptions = new Aspose.Imaging.ImageOptions.EmfRasterizationOptions();

    // The background color of the drawing surface.
    rasterizationOptions.BackgroundColor = Aspose.Imaging.Color.WhiteSmoke;

    // The page size.
    rasterizationOptions.PageSize = emfImage.Size;

    // If embedded emf exists, then render emf; otherwise render wmf.
    rasterizationOptions.RenderMode = Aspose.Imaging.FileFormats.Emf.EmfRenderMode.Auto;

    // Set the horizontal margin
    rasterizationOptions.BorderX = 50;

    // Set the vertical margin
    rasterizationOptions.BorderY = 50;

    saveOptions.VectorRasterizationOptions = rasterizationOptions;

    emfImage.Save(dir + "test.output.svg", saveOptions);
}

This example shows how to load an SVG image from a file and rasterize it to PNG using various options.

[C#]

string dir = "c:\\temp\\";

// Using Aspose.Imaging.Image.Load is a unified way to load image.
using (Aspose.Imaging.FileFormats.Svg.SvgImage svgImage = (Aspose.Imaging.FileFormats.Svg.SvgImage)Aspose.Imaging.Image.Load(dir + "test.svg"))
{
    // In order to rasterize SVG we need to specify rasterization options.
    Aspose.Imaging.ImageOptions.SvgRasterizationOptions rasterizationOptions = new Aspose.Imaging.ImageOptions.SvgRasterizationOptions();

    // Set default color of a background for an image. Default value is white.
    rasterizationOptions.BackgroundColor = Aspose.Imaging.Color.Gray;

    // Set the page size
    rasterizationOptions.PageSize = svgImage.Size;

    // Antialiasing is applied to lines and curves and the edges of filled areas.
    rasterizationOptions.SmoothingMode = Aspose.Imaging.SmoothingMode.AntiAlias;

    // Each character is drawn using its antialiased glyph bitmap without hinting.
    rasterizationOptions.TextRenderingHint = Aspose.Imaging.TextRenderingHint.AntiAlias;

    // Reduce the image size 10 times, i.e. the output size will be 10% of the original size.
    rasterizationOptions.ScaleX = 0.1f;
    rasterizationOptions.ScaleY = 0.1f;

    Aspose.Imaging.ImageOptions.PngOptions saveOptions = new Aspose.Imaging.ImageOptions.PngOptions();
    saveOptions.VectorRasterizationOptions = rasterizationOptions;

    // Save to a PNG file
    svgImage.Save(dir + "test.output.png", saveOptions);
}
