Public API Changes

ISaveOptions::set_DefaultRegularFont() and ISaveOptions::get_DefaultRegularFont() methods have been added

A new methods set_DefaultRegularFont()  and get_DefaultRegularFont() have been added to ISaveOptions interface and SaveOptions abstract class. These methods allow to get or set the default font used instead of all missing fonts during saving presentations to different formats without reloading the presentations with different LoadOptions.

The code snippet below demonstrates saving presentation to Html and Pdf with different default regular font.

System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>(u"SomePresentation.pptx");

System::SharedPtr<HtmlOptions> htmlOpts = System::MakeObject<HtmlOptions>();
htmlOpts->set_DefaultRegularFont(u"Arial Black");
pres->Save(u"SomePresentation-out-ArialBlack.html", Aspose::Slides::Export::SaveFormat::Html, htmlOpts);
htmlOpts->set_DefaultRegularFont(u"Lucida Console");
pres->Save(u"Somepresentation-out-LucidaConsole.html", Aspose::Slides::Export::SaveFormat::Html, htmlOpts);

System::SharedPtr<PdfOptions> pdfOpts = System::MakeObject<PdfOptions>();
pdfOpts->set_DefaultRegularFont(u"Arial Black");
pres->Save(u"SomePresentation-out-ArialBlack.pdf", Aspose::Slides::Export::SaveFormat::Pdf, pdfOpts);
