示例1: RenderLabel

void LocationView::RenderLabel()
{
	if(!GetLabelBindToChart() && m_label->IsVisible() && !App::Inst().GetMouseDragging())
	{
		// get screen coordinates for location
		Point3D winPos = App::Inst().GetMapController()->ProjectToScreen(GetPosition());

		Box2D bb = m_label->GetBoundingBox();

		float size = m_size * App::Inst().GetResolutionFactor();

		// compensate for perspective projection
		float angle = sin(App::Inst().GetViewport()->GetCamera()->GetPitch()*DEG_TO_RAD);
		float perspectiveSize = size * angle;
		float perspectiveTextHeight = bb.Height()*angle;

		// calculate screen position of label
		uint offset = 2 * App::Inst().GetResolutionFactor();

		if(m_label->GetLabelPosition() == _T("Right"))
			m_label->SetScreenPosition(Point3D(winPos.x+size+offset, winPos.y-bb.Height()/3, LABEL_LAYER));
		else if(m_label->GetLabelPosition() == _T("Left"))
			m_label->SetScreenPosition(Point3D(winPos.x-bb.Width()-size-offset, winPos.y-bb.Height()/3, LABEL_LAYER));
		else if(m_label->GetLabelPosition() == _T("Top"))
			m_label->SetScreenPosition(Point3D(winPos.x-bb.Width()/2, winPos.y+perspectiveSize+offset, LABEL_LAYER));
		else if(m_label->GetLabelPosition() == _T("Bottom"))
			m_label->SetScreenPosition(Point3D(winPos.x-bb.Width()/2, winPos.y-perspectiveTextHeight-perspectiveSize, LABEL_LAYER));

		m_label->Render();
	}
