Examples

Shows operating system-dependent font config substitution.

auto fontSettings = System::MakeObject<Aspose::Words::Fonts::FontSettings>();
System::SharedPtr<Aspose::Words::Fonts::FontConfigSubstitutionRule> fontConfigSubstitution = fontSettings->get_SubstitutionSettings()->get_FontConfigSubstitution();

bool isWindows = System::MakeArray<System::PlatformID>({System::PlatformID::Win32NT, System::PlatformID::Win32S, System::PlatformID::Win32Windows, System::PlatformID::WinCE})->LINQ_Any(static_cast<System::Func<System::PlatformID, bool>>(static_cast<std::function<bool(System::PlatformID p)>>([](System::PlatformID p) -> bool
{
    return System::Environment::get_OSVersion().get_Platform() == p;
})));

// The FontConfigSubstitutionRule object works differently on Windows/non-Windows platforms.
// On Windows, it is unavailable.
if (isWindows)
{
    ASSERT_FALSE(fontConfigSubstitution->get_Enabled());
    ASSERT_FALSE(fontConfigSubstitution->IsFontConfigAvailable());
}

bool isLinuxOrMac = System::MakeArray<System::PlatformID>({System::PlatformID::Unix, System::PlatformID::MacOSX})->LINQ_Any(static_cast<System::Func<System::PlatformID, bool>>(static_cast<std::function<bool(System::PlatformID p)>>([](System::PlatformID p) -> bool
{
    return System::Environment::get_OSVersion().get_Platform() == p;
})));

// On Linux/Mac, we will have access to it, and will be able to perform operations.
if (isLinuxOrMac)
{
    ASSERT_TRUE(fontConfigSubstitution->get_Enabled());
    ASSERT_TRUE(fontConfigSubstitution->IsFontConfigAvailable());

    fontConfigSubstitution->ResetCache();
}
