GDI-我可以使用新的Windows10SegoeUIEmoji彩色字体和DrawText吗？

输出结果在符号方面听起来不错,但它们以黑白绘制,没有颜色,如下面的屏幕截图所示:

我找不到任何其他选项可能允许使用彩色符号而不是黑白绘制文本.有没有办法在GDI DrawText()函数中激活颜色的支持,如果是的话,怎么做？或者只有Direct2D可以绘制彩色表情符号？

由于GDI无法完成这项工作(不幸的是,正如我所想),我在这里发布了上述代码的Direct2D版本,这对我有用.

const std::wstring text = L"Test        ";

HDC hDC = ::GetDC(Handle);

std::auto_ptr pGDICanvas(new TCanvas());
pGDICanvas->Handle = hDC;

pGDICanvas->Brush->Color = clWhite;
pGDICanvas->Brush->Style = bsSolid;
pGDICanvas->FillRect(TRect(0, 0, ClientWidth, ClientHeight));

::D2D1_RECT_F textRect;
textRect.left   = 10;
textRect.top    = 10;
textRect.right  = ClientWidth  - 10;
textRect.bottom = ClientHeight - 10;

std::auto_ptr pCanvas(new TDirect2DCanvas(hDC, TRect(0, 0, ClientWidth, ClientHeight)));

// configure Direct2D font
pCanvas->Font->Size        = 40;
pCanvas->Font->Name        = L"Segoe UI Emoji";
pCanvas->Font->Orientation = 0;
pCanvas->Font->Pitch       = System::Uitypes::TFontPitch::fpVariable;
pCanvas->Font->Style       = TFontStyles();

// get DirectWrite text format object
_di_IDWriteTextFormat pFormat = pCanvas->Font->Handle;

if (!pFormat)
    return;

pCanvas->RenderTarget->SetTextAntialiasMode(D2D1_TEXT_ANTIALIAS_MODE_CLEARTYPE);

::D2D1_COLOR_F color;
color.r = 0.0f;
color.g = 0.0f;
color.b = 0.0f;
color.a = 1.0f;

::ID2D1SolidColorBrush* pBrush = NULL;

// create solid color brush, use pen color if rect is completely filled with outline
pCanvas->RenderTarget->CreateSolidColorBrush(color, &pBrush);

if (!pBrush)
    return;

// set horiz alignment
pFormat->SetTextAlignment(DWRITE_TEXT_ALIGNMENT_LEADING);

// set vert alignment
pFormat->SetParagraphAlignment(DWRITE_PARAGRAPH_ALIGNMENT_NEAR);

// set reading direction
pFormat->SetReadingDirection(DWRITE_READING_DIRECTION_LEFT_TO_RIGHT);

// set word wrapping mode
pFormat->SetWordWrapping(DWRITE_WORD_WRAPPING_NO_WRAP);

IDWriteInlineObject* pInlineObject = NULL;

::DWRITE_TRIMMING trimming;
trimming.delimiter      = 0;
trimming.delimiterCount = 0;
trimming.granularity    = DWRITE_TRIMMING_GRANULARITY_NONE;

// set text trimming
pFormat->SetTrimming(&trimming, pInlineObject);

pCanvas->BeginDraw();

pCanvas->RenderTarget->DrawText(text.c_str(), text.length(), pFormat, textRect, pBrush,
            D2D1_DRAW_TEXT_OPTIONS_ENABLE_COLOR_FONT);

pCanvas->EndDraw();
