VC++ Codes: Draw text along line and draw rotate text


draw text along line or draw rotate text

void CAestheticLinesView::OnLButtonUp(UINT nFlags, CPoint point)

    // the mouse if it's currently captured, erase the last rubber-band
    // line, and draw a thick red line in its place.

		CFont fnt;
		fnt.CreateFontIndirect(&lf);//Create a Font object for the current Font
		dc.SetBkMode(TRANSPARENT);//To see that there's no clutter incase of overlap 
		dc.SelectObject(fnt);//Select the font for drawing text

		CString str;
		str=0x96;//0x5A ; //0xCB;//0x5E;//0x5D;//0xCB;//0x5c;//Hexadecimal value of the desired character/symbol from Character Map

		CSize sz=dc.GetTextExtent(str);//Do not use strlen() function

		//Length of line segement

		dc.TextOut(m_ptFrom.x,m_ptFrom.y,str);//Voila !! , Here's is the Line Pattern


		CView::OnLButtonUp(nFlags, point);
