如何生成带抗锯齿字体渲染的位图输出？

调整正确的 DC

使用以下屏幕 DC 来创建带抗锯齿选项的字体渲染（按屏幕调整）：

HDC dc = CreateDC(TEXT("DISPLAY"),NULL,NULL,NULL);
eCode = BCSaveImageEx(m_pbarCode, dc, file, imageType, 100, widthPx, heightPx, dpi, dpi );

if (dc)
    DeleteDC(dc);

调整正确的字体（LOGFONT）

使用 Windows 标准字体对话框，或使用以下函数从 Windows GDI 获取一个预初始化的 LOGFONT 结构：

HFONT hSystemVariableFont = (HFONT ) GetStockObject( ANSI_VAR_FONT );
LOGFONT lfSystemVariableFont;
GetObject ( hSystemVariableFont, sizeof(LOGFONT), &lfSystemVariableFont );

// Make sure that the following flags are set in the LOGFONT structure passed to BCSetLogFont():

lfOutPrecision (e.g. set to 3)
lfClipPrecision (e.g. set to 2)
lfQuality (e.g. set to 1)
lfWeight (e.g. set to 400)

lfFaceName should be set to a True Type font (e.g. “Arial”)

// Calculate the font height as follows:
lfHeight = = -MulDiv( 10 /*PointSize*/, GetDeviceCaps(hDC, LOGPIXELSY), 72);
