C++ (Cpp) GraphicsPath::AddCurve Examples

Example #1

File: CTransparentPen.cpp Project: lilingshui/code-refrence

void CTransparentPen::SetRegion()
{
	PointF* pPt = m_ptary.GetData();

	Pen penDraw(m_crColor);
	penDraw.SetStartCap(LineCapRound);
	penDraw.SetEndCap(LineCapRound);
	penDraw.SetLineJoin(LineJoinRound);
	penDraw.SetWidth(m_nWidth * m_fScale);

	GraphicsPath path;
	path.AddCurve(pPt,m_nPtCount,0.8f);
	path.Widen(&penDraw);
	path.Outline();

	m_Region.MakeEmpty();
	m_Region.Union(&path);
}

Example #2

File: CFlatBrushPen.cpp Project: chenboo/code-refrence

void CFlatBrushPen::SetRegion()
{
	ASSERT(m_bFinish);
	PointF* pPt = m_ptary.GetData();
	float fwidth = m_nWidth * m_fScale;

	Pen penDraw(m_crColor, fwidth);
	penDraw.ScaleTransform(1, 2.0f / fwidth, MatrixOrderAppend);
	penDraw.RotateTransform(m_ftransAngle, MatrixOrderAppend);

	GraphicsPath path;
	path.AddCurve(pPt, m_nPtCount);
	path.Widen(&penDraw);
	path.Outline();

	m_Region.MakeEmpty();
	m_Region.Union(&path);
}
