Examples

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

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

# to determine how the saving operation handles this object.
# Setting the "metafile_format" property to "HtmlMetafileFormat.PNG" to convert it to a PNG image.
# Setting the "metafile_format" property to "HtmlMetafileFormat.SVG" preserve it as a SVG object.
# Setting the "metafile_format" property to "HtmlMetafileFormat.EMF_OR_WMF" to convert it to a metafile.
