แปลง TTF เป็น WOFF2 ด้วย C++ API

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);

วิธีโหลดและดึงข้อมูลจากฟอนต์ Type1 ด้วย C++ API?

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));

วิธีการเรนเดอร์ข้อความด้วย Glyphs ในแอปพลิเคชัน C++?

 using Aspose::Font::Glyphs;
using Aspose::Font::Rendering;
using Aspose::Font::RenderingPath;

class GlyphOutlinePainter: IGlyphOutlinePainter
    RenderingText::GlyphOutlinePainter::GlyphOutlinePainter(System::SharedPtr path)
    {
        _path = path;
    }
    void RenderingText::GlyphOutlinePainter::MoveTo(System::SharedPtr moveTo)
    {
        _path->CloseFigure();
        _currentPoint.set_X((float)moveTo->get_X());
        _currentPoint.set_Y((float)moveTo->get_Y());
    }

    void RenderingText::GlyphOutlinePainter::LineTo(System::SharedPtr lineTo)
    {
        float x = (float)lineTo->get_X();
        float y = (float)lineTo->get_Y();
        _path->AddLine(_currentPoint.get_X(), _currentPoint.get_Y(), x, y);
        _currentPoint.set_X(x);
        _currentPoint.set_Y(y);
    }

    void RenderingText::GlyphOutlinePainter::CurveTo(System::SharedPtr curveTo)
    {
        float x3 = (float)curveTo->get_X3();
        float y3 = (float)curveTo->get_Y3();
    
        _path->AddBezier(_currentPoint.get_X(), _currentPoint.get_Y(), (float)curveTo->get_X1(), (float)curveTo->get_Y1(), (float)curveTo->get_X2(), (float)curveTo->get_Y2(), x3, y3);
    
        _currentPoint.set_X(x3);
        _currentPoint.set_Y(y3);
    }

    void RenderingText::GlyphOutlinePainter::ClosePath()
    {
        _path->CloseFigure();
    }

    System::Object::shared_members_type Aspose::Font::Examples::WorkingWithTrueTypeAndOpenTypeFonts::RenderingText::GlyphOutlinePainter::GetSharedMembers()
    {
        auto result = System::Object::GetSharedMembers();
    
        result.Add("Aspose::Font::Examples::WorkingWithTrueTypeAndOpenTypeFonts::RenderingText::GlyphOutlinePainter::_path", this->_path);      result.Add("Aspose::Font::Examples::WorkingWithTrueTypeAndOpenTypeFonts::RenderingText::GlyphOutlinePainter::_currentPoint", this->_currentPoint);
    
        return result;
