We are pleased to announce the release of GroupDocs.Viewer for .NET 18.10. The latest version allows setting the list of the fonts that should be excluded from the output HTML to decrease the size of the output files. Furthermore, the inclusion of 5 improvements and 6 bug fixes have made the API more promising. Below is the list of new features, improvements, and fixes added in v18.10.
Features Introduced
Setting List of the Fonts to be Excluded
Adding fonts into HTML ensures that the text from the original document will appear similar in HTML, regardless of whether fonts are installed on the viewer’s device or not. At the same time, this improvement comes with the cost of the increased size of the output file. Therefore, GroupDocs.Viewer API provides a new setting – HtmlOptions.ExcludeFontsList, that prevents adding specific fonts (that are commonly available on most of the devices). The code sample below shows how to prevent adding fonts into output HTML.// Setup GroupDocs.Viewer config
ViewerConfig config = new ViewerConfig();
config.StoragePath = @"C:\storage";
// Create html handler
ViewerHtmlHandler htmlHandler = new ViewerHtmlHandler(config);
string guid = "presentation.pptx";
HtmlOptions options = new HtmlOptions();
options.ExcludeFontsList.Add("Times New Roman");
options.ExcludeFontsList.Add("Arial");
List pages = htmlHandler.GetPages(guid, options);
foreach (PageHtml page in pages)
{
Console.WriteLine("Page number: {0}", page.PageNumber);
Console.WriteLine("Html content: {0}", page.HtmlContent);
}
