The code below illustrates the problem I am having. A rectangle is drawn in
the center of the display. Text is suppose to be drawn at a 270 degree
angle and centered in the middle of the rectangle. Instead, the text is
always drawn to the far to the left of the rectangle. If I change text
escapement to 0 degrees then the text is correctly centered. Can someone
suggest what mistake I am making? Thanks in advance.

CMyView::OnDraw( CDC *pDC )
{
    // create font
    CFont oFont;
    LOGFONT oLF;
    memset( &oLF, 0, sizeof(oLF) );
    oLF.lfHeight = 25;
    oLF.lfOrientation = 2700; // 270 degrees
    oLF.lfEscapement = 2700;
    VERIFY( oFont.CreateFontIndirect( &oLF ) );
    CFont *pOldFont = pDC->SelectObject( &oFont );
    ASSERT( pOldFont );

    // set drawing rectangle
    CRect oCR;
    GetClientRect( &oCR );
    CRect oR(
        oCR.CenterPoint().x-30, oCR.top,
        oCR.CenterPoint().x+30, oCR.bottom
    );
    pDC->DPtoLP( &oR );

    // draw rectangle
    CBrush oBrush( RGB(0,0,0) );
    pDC->FrameRect( &oR, &oBrush );

    // draw text
    pDC->SetTextColor( RGB(0,0,0) );
    UINT uFormat = DT_SINGLELINE | DT_TOP | DT_CENTER | DT_NOCLIP;
    pDC->DrawTextEx( _T("sample text"), &oR, uFormat, NULL );

    // clean up
    pDC->SelectObject( pOldFont );
}
