## HtmlSaveOptions.metafileFormat property Specifies in what format metafiles are saved when exporting to HTML, MHTML, or EPUB. Default value is [HtmlMetafileFormat.Png](../../htmlmetafileformat/#Png), meaning that metafiles are rendered to raster PNG images. ```js get metafileFormat(): Aspose.Words.Saving.HtmlMetafileFormat ``` ### Remarks Metafiles are not natively displayed by HTML browsers. By default, Aspose.Words converts WMF and EMF images into PNG files when exporting to HTML. Other options are to convert metafiles to SVG images or to export them as is without conversion. Some image transforms, in particular image cropping, will not be applied to metafile images if they are exported to HTML without conversion. ### Examples Shows how to convert SVG objects to a different format when saving HTML documents. ```js let html = ` Hello world! ` // 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. let loadOptions = new aw.Loading.HtmlLoadOptions(); loadOptions.convertSvgToEmf = true; let doc = new aw.Document(Buffer.from(html, 'utf-8'), loadOptions); // This document contains a 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. let options = new aw.Saving.HtmlSaveOptions(); options.metafileFormat = htmlMetafileFormat; doc.save(base.artifactsDir + "HtmlSaveOptions.metafileFormat.html", options); let outDocContents = fs.readFileSync(base.artifactsDir + "HtmlSaveOptions.metafileFormat.html").toString(); switch (htmlMetafileFormat) { case aw.Saving.HtmlMetafileFormat.Png: expect(outDocContents.includes( "

" + "\"\"" + "

")).toEqual(true); break; case aw.Saving.HtmlMetafileFormat.Svg: expect(outDocContents.includes( "" + "")).toEqual(true); break; case aw.Saving.HtmlMetafileFormat.EmfOrWmf: expect(outDocContents.includes( "

" + "\"\"" + "

")).toEqual(true); break; } ``` ### See Also * module [Aspose.Words.Saving](../../) * class [HtmlSaveOptions](../) * property [HtmlSaveOptions.imageResolution](../imageResolution/) * property [HtmlSaveOptions.scaleImageToShapeSize](../scaleImageToShapeSize/)
