Initializes a new instance of this class that can be used to save a document in the Pdf format.

Aspose::Words::Saving::PdfSaveOptions::PdfSaveOptions()

Examples

Shows how to enable or disable subsetting when embedding fonts while rendering a document to PDF.

auto doc = MakeObject<Document>();
auto builder = MakeObject<DocumentBuilder>(doc);

builder->get_Font()->set_Name(u"Arial");
builder->Writeln(u"Hello world!");
builder->get_Font()->set_Name(u"Arvo");
builder->Writeln(u"The quick brown fox jumps over the lazy dog.");

// Configure our font sources to ensure that we have access to both the fonts in this document.
ArrayPtr<SharedPtr<FontSourceBase>> originalFontsSources = FontSettings::get_DefaultInstance()->GetFontsSources();
auto folderFontSource = MakeObject<FolderFontSource>(FontsDir, true);
FontSettings::get_DefaultInstance()->SetFontsSources(MakeArray<SharedPtr<FontSourceBase>>({originalFontsSources[0], folderFontSource}));

ArrayPtr<SharedPtr<FontSourceBase>> fontSources = FontSettings::get_DefaultInstance()->GetFontsSources();
ASSERT_TRUE(fontSources[0]->GetAvailableFonts()->LINQ_Any([](SharedPtr<PhysicalFontInfo> f) { return f->get_FullFontName() == u"Arial"; }));
ASSERT_TRUE(fontSources[1]->GetAvailableFonts()->LINQ_Any([](SharedPtr<PhysicalFontInfo> f) { return f->get_FullFontName() == u"Arvo"; }));

// Create a "PdfSaveOptions" object that we can pass to the document's "Save" method
// to modify how that method converts the document to .PDF.
auto options = MakeObject<PdfSaveOptions>();

// Since our document contains a custom font, embedding in the output document may be desirable.
// Set the "EmbedFullFonts" property to "true" to embed every glyph of every embedded font in the output PDF.
// The document's size may become very large, but we will have full use of all fonts if we edit the PDF.
// Set the "EmbedFullFonts" property to "false" to apply subsetting to fonts, saving only the glyphs
// that the document is using. The file will be considerably smaller,
// but we may need access to any custom fonts if we edit the document.
options->set_EmbedFullFonts(embedFullFonts);

doc->Save(ArtifactsDir + u"PdfSaveOptions.EmbedFullFonts.pdf", options);

if (embedFullFonts)
{
    ASSERT_LT(500000, MakeObject<System::IO::FileInfo>(ArtifactsDir + u"PdfSaveOptions.EmbedFullFonts.pdf")->get_Length());
}
else
{
    ASSERT_GE(25000, MakeObject<System::IO::FileInfo>(ArtifactsDir + u"PdfSaveOptions.EmbedFullFonts.pdf")->get_Length());
}

// Restore the original font sources.
FontSettings::get_DefaultInstance()->SetFontsSources(originalFontsSources);
