How to draw Markup with CMetaFileDC?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I want to draw Markup with CMetaFileDC in CDocObjectServerItem::OnDraw(CDC* pDC, CSize& rSize), but it fails to render.
BOOL CMySrvrItem::OnDraw(CDC* pDC, CSize& rSize)
{
 if (!pDC)
  return FALSE;
 // Remove this if you use rSize
 UNREFERENCED_PARAMETER(rSize);
 // TODO: set mapping mode and extent
 //  (The extent is usually the same as the size returned from OnGetExtent)
 pDC->SetMapMode(MM_ANISOTROPIC);
 pDC->SetWindowOrg(0,0);
 pDC->SetWindowExt(3000, 3000);
 // TODO: add drawing code here.  Optionally, fill in the HIMETRIC extent.
 //  All drawing takes place in the metafile device context (pDC).
 if (m_pUIElement)
 {
  CXTPMarkupDrawingContext dc(pDC->m_hDC);
  CRect rc(0, 0, 3000, 3000);
  m_pUIElement->Measure(&dc, rc.Size());
  m_pUIElement->Arrange(rc);
  m_pUIElement->Render(&dc);
 }
 return TRUE;
}

Please help me.

	Hi, You can Render it to Buffer DC and then stretch to pDC: BOOL CDocSrvrItem::OnDraw(CDC* pDC, CSize& rSize) { // Remove this if you use rSize UNREFERENCED_PARAMETER(rSize); CDocDoc* pDoc = GetDocument(); ASSERT_VALID(pDoc); // TODO: set mapping mode and extent // (The extent is usually the same as the size returned from OnGetExtent) pDC->SetMapMode(MM_TEXT); pDC->SetWindowOrg(0,0); pDC->SetWindowExt(3000, 3000); CXTPMarkupContext* pContext = XTPMarkupCreateContext(0); CXTPMarkupUIElement* pElement = XTPMarkupParseText(pContext, _T("<Ellipse Stroke='Yellow' StrokeThickness='3' Fill='Blue' Width='100' Height='100'/>")); XTPMarkupMeasureElement(pElement, 100, 100); CWindowDC dcWindow(0); CDC dc; dc.CreateCompatibleDC(&dcWindow); CBitmap bmp; bmp.CreateCompatibleBitmap(&dcWindow, 100, 100); CBitmap* pOldBitmap = dc.SelectObject(&bmp); dc.FillSolidRect(0, 0, 100, 100, 0xFF); if (pElement) { XTPMarkupRenderElement(pElement, dc, CRect(0, 0, 100, 100)); XTPMarkupReleaseElement(pElement); } pDC->StretchBlt(0, 0, 100, 100, &dc, 0, 0, 100, 100, SRCCOPY); dc.SelectObject(pOldBitmap); XTPMarkupReleaseContext(pContext); return TRUE; }
