## Document::get_FontSettings method


Gets or sets document font settings.

```cpp
System::SharedPtr<Aspose::Words::Fonts::FontSettings> Aspose::Words::Document::get_FontSettings() const
```

## Remarks


This property allows to specify font settings per document. If set to **null**, default static font settings [DefaultInstance](../../../aspose.words.fonts/fontsettings/get_defaultinstance/) will be used.

The default value is **null**.

## Examples



Shows how set font substitution rules. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>();
auto builder = System::MakeObject<Aspose::Words::DocumentBuilder>(doc);

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

System::ArrayPtr<System::SharedPtr<Aspose::Words::Fonts::FontSourceBase>> fontSources = FontSettings::get_DefaultInstance()->GetFontsSources();

// The default font sources contain the first font that the document uses.
ASSERT_EQ(1, fontSources->get_Length());
ASSERT_TRUE(fontSources[0]->GetAvailableFonts()->LINQ_Any(static_cast<System::Func<System::SharedPtr<Aspose::Words::Fonts::PhysicalFontInfo>, bool>>(static_cast<std::function<bool(System::SharedPtr<Aspose::Words::Fonts::PhysicalFontInfo> f)>>([](System::SharedPtr<Aspose::Words::Fonts::PhysicalFontInfo> f) -> bool
{
    return f->get_FullFontName() == u"Arial";
}))));

// The second font, "Amethysta", is unavailable.
ASSERT_FALSE(fontSources[0]->GetAvailableFonts()->LINQ_Any(static_cast<System::Func<System::SharedPtr<Aspose::Words::Fonts::PhysicalFontInfo>, bool>>(static_cast<std::function<bool(System::SharedPtr<Aspose::Words::Fonts::PhysicalFontInfo> f)>>([](System::SharedPtr<Aspose::Words::Fonts::PhysicalFontInfo> f) -> bool
{
    return f->get_FullFontName() == u"Amethysta";
}))));

// We can configure a font substitution table which determines
// which fonts Aspose.Words will use as substitutes for unavailable fonts.
// Set two substitution fonts for "Amethysta": "Arvo", and "Courier New".
// If the first substitute is unavailable, Aspose.Words attempts to use the second substitute, and so on.
doc->set_FontSettings(System::MakeObject<Aspose::Words::Fonts::FontSettings>());
doc->get_FontSettings()->get_SubstitutionSettings()->get_TableSubstitution()->SetSubstitutes(u"Amethysta", System::MakeArray<System::String>({
    u"Arvo", u"Courier New"}));

// "Amethysta" is unavailable, and the substitution rule states that the first font to use as a substitute is "Arvo".
ASSERT_FALSE(fontSources[0]->GetAvailableFonts()->LINQ_Any(static_cast<System::Func<System::SharedPtr<Aspose::Words::Fonts::PhysicalFontInfo>, bool>>(static_cast<std::function<bool(System::SharedPtr<Aspose::Words::Fonts::PhysicalFontInfo> f)>>([](System::SharedPtr<Aspose::Words::Fonts::PhysicalFontInfo> f) -> bool
{
    return f->get_FullFontName() == u"Arvo";
}))));

// "Arvo" is also unavailable, but "Courier New" is.
ASSERT_TRUE(fontSources[0]->GetAvailableFonts()->LINQ_Any(static_cast<System::Func<System::SharedPtr<Aspose::Words::Fonts::PhysicalFontInfo>, bool>>(static_cast<std::function<bool(System::SharedPtr<Aspose::Words::Fonts::PhysicalFontInfo> f)>>([](System::SharedPtr<Aspose::Words::Fonts::PhysicalFontInfo> f) -> bool
{
    return f->get_FullFontName() == u"Courier New";
}))));

// The output document will display the text that uses the "Amethysta" font formatted with "Courier New".
doc->Save(get_ArtifactsDir() + u"FontSettings.TableSubstitution.pdf");
```
