Detailed Description

CHistogramView is a holder for the renderer, calculates histograms, and takes care of window resizes and mouse/limit bar movements.

Definition at line 21 of file HistogramView.h.

Constructor & Destructor Documentation

scope::gui::CHistogramView::CHistogramView	(	const uint32_t &	_area,
		const uint32_t &	_channels,
		uint16_t	_range
	)

Initialize everything.

Member Function Documentation

void scope::gui::CHistogramView::SetLimits ( )

protected

Set limits in renderer and scope_controller.

Definition at line 123 of file HistogramView.cpp.

void scope::gui::CHistogramView::UpdateHistogramFrame ( )

protected

Update Histogram with current parameters.

Definition at line 138 of file HistogramView.cpp.

scope::gui::CHistogramView::DECLARE_WND_CLASS_EX	(	nullptr	,
		CS_HREDRAW\|	CS_VREDRAW,
		-	1
	)

Set background brush to -1, avoids erasure of background (similar effect as OnEraseBkgnd below...)

void scope::gui::CHistogramView::OnFinalMessage ( HWND )

virtual

Do not do 'delete this;' because view is a member of frame and gets destroyed when frame is destroyed.

Definition at line 26 of file HistogramView.cpp.

void scope::gui::CHistogramView::OnShowWindow	(	BOOL	bShow,
		UINT	nStatus
	)

Create the renderer only now, because now the window is shown.

Definition at line 73 of file HistogramView.cpp.

void scope::gui::CHistogramView::OnLButtonDown	(	UINT	nFlags,
		CPoint	point
	)

Ask renderer for hit test and set click state.

Definition at line 29 of file HistogramView.cpp.

void scope::gui::CHistogramView::OnLButtonUp	(	UINT	nFlags,
		CPoint	point
	)

Releases click state.

Definition at line 44 of file HistogramView.cpp.

void scope::gui::CHistogramView::OnMouseMove	(	UINT	nFlags,
		CPoint	point
	)

If moving with left mouse button down, give position to Renderer and render limit bars.

Definition at line 50 of file HistogramView.cpp.

LRESULT scope::gui::CHistogramView::OnEraseBkgnd ( HDC wParam )

inline

avoids flickering during resize

Definition at line 112 of file HistogramView.h.

void scope::gui::CHistogramView::OnPaint ( CDCHandle )

Render the histogram and the limit bars (both via Renderer)

Definition at line 83 of file HistogramView.cpp.

void scope::gui::CHistogramView::OnSize	(	UINT	,
		CSize	_size
	)

Resize the Renderer accordingly, be careful not to resize to 0.

Definition at line 91 of file HistogramView.cpp.

void scope::gui::CHistogramView::Optimize ( )

Set lower limit to the first value with count >0 and the upper limit to the last value with count >0.

Optimizes dynamic range for display.

Definition at line 101 of file HistogramView.cpp.

void scope::gui::CHistogramView::FullRange ( )

Set lower and upper limits to full range.

Definition at line 113 of file HistogramView.cpp.

void scope::gui::CHistogramView::SetCurrentFrame	(	scope::SCOPE_MULTIIMAGECPTR_T const	_multi,
		const bool &	_loghisto
	)

Sets the current frame and calculates its histogram (either with regular count or with logarithmic counts)

Definition at line 145 of file HistogramView.cpp.

uint16_t scope::gui::CHistogramView::LowerLimit ( const uint32_t & _ch ) const

inline

Render histogram and limit bars.

Definition at line 136 of file HistogramView.h.
