ConvertSvgToEmf

HtmlLoadOptions.ConvertSvgToEmf property

Gets or sets a value indicating whether to convert loaded SVG images to the EMF format. Default value is false and, if possible, loaded SVG images are stored as is without conversion.

public bool ConvertSvgToEmf { get; set; }

Remarks

Newer versions of MS Word support SVG images natively. If the MS Word version specified in load options supports SVG, Aspose.Words will store SVG images as is without conversion. If SVG is not supported, loaded SVG images will be converted to the EMF format.

If, however, this option is set to true, Aspose.Words will convert loaded SVG images to EMF even if SVG images are supported by the specified version of MS Word.

Examples

Shows how to convert SVG objects to a different format when saving HTML documents.

string html = 
    @"<html>
        <svg xmlns='http://www.w3.org/2000/svg' width='500' height='40' viewBox='0 0 500 40'>
            <text x='0' y='35' font-family='Verdana' font-size='35'>Hello world!</text>
        </svg>
    </html>";

// Use 'ConvertSvgToEmf' to turn back the legacy behavior
// where all SVG images loaded from an HTML document were converted to EMF.
// Now SVG images are loaded without conversion
// if the MS Word version specified in load options supports SVG images natively.
HtmlLoadOptions loadOptions = new HtmlLoadOptions { ConvertSvgToEmf = true };

Document doc = new Document(new MemoryStream(Encoding.UTF8.GetBytes(html)), loadOptions);

// This document contains a <svg> element in the form of text.
// When we save the document to HTML, we can pass a SaveOptions object
// to determine how the saving operation handles this object.
// Setting the "MetafileFormat" property to "HtmlMetafileFormat.Png" to convert it to a PNG image.
// Setting the "MetafileFormat" property to "HtmlMetafileFormat.Svg" preserve it as a SVG object.
// Setting the "MetafileFormat" property to "HtmlMetafileFormat.EmfOrWmf" to convert it to a metafile.
HtmlSaveOptions options = new HtmlSaveOptions { MetafileFormat = htmlMetafileFormat };

doc.Save(ArtifactsDir + "HtmlSaveOptions.MetafileFormat.html", options);

string outDocContents = File.ReadAllText(ArtifactsDir + "HtmlSaveOptions.MetafileFormat.html");

switch (htmlMetafileFormat)
{
    case HtmlMetafileFormat.Png:
