I'm trying to print an IE CWebBrowser2 control to a Metafile.
I'm using IViewObject::Draw method.
In order to fit the IE control to the page size I'm using the
lprcBounds parameter of IViewObject::Draw.
Unfortunately, stretching don't work properly: only the top-left
corner is stretched and the e rest of the IE control is ignored by the
metafile.
Adjusting lprcWBounds has no effect.
Is it a bug in the Microsoft IE control?
I don't use StretchBlt method because it's distorting fonts.
How can I stretch and draw the whole IE control to a metafile?

Would it be possible for you to post a short code snippet to look at?

Here you have some code  
if(!mpWeb) return; //mpWeb is a CDialog holding IE control
 CWebBrowser2* pWB = &mpWeb->m_web;
 IViewObject2* pViewObject = NULL;
 HRESULT   hr = pWB->GetDocument()->QueryInterface(IID_IViewObject2,
(void**)             &pViewObject);
 if (FAILED(hr)) return;
 //get size of control 
 CRect rect;
 pWB->GetWindowRect(&rect);
 int srcWidth = rect.Width(),  srcHeight = rect.Height();
 float factor = mStretch;//2;   //the  strectch factor is a member of
this class
 if(factor <= 0) factor = 1;
 
 RECTL rcOrig = { 0,0, srcWidth,srcHeight };
 RECTL rcBounds = { 0,0, (int)(srcWidth*factor),(int)(
srcHeight*factor)};
 RECTL rcWBounds = { 0,0, (int)(srcWidth*factor)*2,(int)(
srcHeight*factor)*2};
 
 // good quality but there is a bug: top-left corner only is stretched
 
      hr = pViewObject->Draw(DVASPECT_CONTENT, //DOCPRINT,
           -1, NULL, NULL,pWB->GetDC()->m_hDC ,
((CMetaFileDC*)pDC)->m_hDC, //hdcMem,
           &rcBounds, &rcWBounds, NULL, 0);
          if (!SUCCEEDED(hr)) ASSERT(0);
 
 
 pViewObject->Release();
