تحويل TTF إلى WOFF2 باستخدام واجهة برمجة التطبيقات C++

using namespace System;
    using namespace Aspose::Font::Sources;
    using namespace Aspose::Font::Ttf;
    using namespace Aspose::Font;

    // Open TTF font
    SharedPtr fontFileDefinition = MakeObject(MakeObject(u"Montserrat-Regular.ttf"));
    SharedPtr fontDefinition = MakeObject(FontType::TTF, fontFileDefinition);
    SharedPtr font = Font::Open(fontDefinition);

    // WOFF2 output settings
    SharedPtr outStream = IO::File::Create(u"Montserrat-Regular.woff2");

    // Convert TTF to WOFF2
    font->SaveToFormat(outStream, FontSavingFormats::WOFF2);

كيفية تحميل واستخراج البيانات من خطوط Type1 باستخدام واجهة برمجة التطبيقات C++؟

System::String fileName = dataDir + u"courier.pfb";
//Font file name with full path
    
System::SharedPtr fd = System::MakeObject(Aspose::Font::FontType::Type1, System::MakeObject(u"pfb", System::MakeObject(fileName)));
System::SharedPtr font = System::DynamicCast_noexcept(Aspose::Font::Font::Open(fd));

كيف يتم عرض النص مع الحروف في تطبيقات C++؟
