本人用以下代碼獲取TTF字符輪廓，用vc6運行成功，但是獲得的點數太少。造成字體不太圓滑。求大神指點怎樣增多獲取的點數？
HDC hDC = pDC->GetSafeHdc();
//創建字體
CFont font;
VERIFY(font.CreateFont(m_iFontHeight, 0, 0, 0,FW_NORMAL, FALSE, FALSE, 0, ANSI_CHARSET,OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY, DEFAULT_PITCH | FF_SWISS,m_sFontFaceName));
CFont *pOldFont = pDC->SelectObject(&font);
//定義并初始化變換矩陣
MAT2 mat2;
memset(&mat2, 0, sizeof(mat2));
mat2.eM11 = 1;
mat2.eM22 = 1;
GLYPHMETRICS metrics; //保存字符相關資訊
DWORD dwDataSize = 0; //初始化字符資料緩沖區大小
//……
//通過函式GetGlyphOutline()確定存盤字符結構的空間
dwDataSize = pDC->GetGlyphOutline(nChar, GGO_NATIVE, &metrics, 0, NULL, &mat2);
if ((dwDataSize != 0) && (dwDataSize != GDI_ERROR))
{
//創建保存字符資料緩沖區大小
LPBYTE pPixels = new BYTE[dwDataSize];
ASSERT( pPixels != NULL );
TTPOLYGONHEADER *pHeader = (TTPOLYGONHEADER*)pPixels;
dwDataSize = pDC->GetGlyphOutline(nChar,GGO_NATIVE,&metrics, dwDataSize, pPixels, &mat2);
while(dwDataSize > 0)
{
//計算字符輪廓的起點，轉換坐標
int xOld = MapFXY(pHeader->pfxStart.x);
int yOld = MapFXY(pHeader->pfxStart.y);
//根據TTF字體結構獲取字符輪廓
::MoveToEx(hDC,iXpos + xOld,iYpos - yOld,NULL);
TTPOLYCURVE *pCurrentCurve = (TTPOLYCURVE*)(pHeader + 1);
int remainByte = pHeader->cb - sizeof(TTPOLYGONHEADER);
while (remainByte > 0)
{
CPoint lpPoint[1000];
CPoint bezi[2];
int index;
for (index = 0; index < pCurrentCurve->cpfx; ++index)
{
lpPoint[index].x = iXpos + MapFXY(pCurrentCurve->apfx[index].x);
lpPoint[index].y = iYpos - MapFXY(pCurrentCurve->apfx[index].y);
}
switch (pCurrentCurve->wType)
{
case TT_PRIM_LINE:
case TT_PRIM_QSPLINE:
for (index =0; index < pCurrentCurve->cpfx; index++)
{
::LineTo(hDC,lpPoint[index].x,lpPoint[index].y);
}
break;
default:
MessageBox(_T("字體不支持"));
break;
}
int count = sizeof(TTPOLYCURVE) + (pCurrentCurve->cpfx -1)*sizeof(POINTFX);
pCurrentCurve = (TTPOLYCURVE*)((char*)pCurrentCurve + count);
remainByte -= count;
}
::LineTo(hDC,iXpos + xOld, iYpos - yOld);
dwDataSize -= pHeader->cb;
pHeader = (TTPOLYGONHEADER*)((char*)pHeader + pHeader->cb);
}
delete [] pPixels;
}
}
