高手帮忙看下GetGlyphOutline函数问题
DWORD nLen=::GetGlyphOutline(pdc->GetSafeHdc(),chartemp,GGO_BITMAP,&glpm,0,NULL,&mmat2);
（signed)nLen = -1;
请问高手，这是怎么回事呢？？？？
------解决方案--------------------
If GGO_BITMAP, GGO_GRAY2_BITMAP, GGO_GRAY4_BITMAP, GGO_GRAY8_BITMAP, or GGO_NATIVE is specified and the function succeeds, the return value is greater than zero; otherwise, the return value is GDI_ERROR. If one of these flags is specified and the buffer size or address is zero, the return value specifies the required buffer size, in bytes.
If GGO_METRICS is specified and the function fails, the return value is GDI_ERROR.
