void TFEditDialog::DoDataExchange

(

CDataExchange *

pDX

)

[protected, virtual]

void TFEditDialog::GetColorControlPos	(	CPoint	point,
		int &	xPos,
		double &	zoomFaktorX
	)			[private]

Returns the relative position of a point in the color control window. It is used to determine the position in the color control window on a mouse click, taking into account the current zoom factor and the current x offset

Parameters:

	point	Mouse position
	xPos	Relative x position in the color control window
	zoomFaktorX	current zoom Factor set for color control window

void TFEditDialog::GetOpacityControlPos	(	CPoint	point,
		int &	xPos,
		float &	yPos,
		double &	zoomFaktorX,
		double &	zoomFaktorY
	)			[private]

Returns the relative position of a point in the opacity control window. It is used to determine the position in the opacity control window on a mouse click, taking into account the current zoom factor and the current x and y offset

Parameters:

	point	Mouse position
	xPos	Relative x position in the opacity control window
	yPos	Relative y psoition in the opacity control window
	zoomFaktorX	X zoom factor set for opacity control window
	zoomFaktorY	Y zoom factor set for opacity control window

The position of the mouse cursor is converted into a density value (x direction) and a opacity value (y direction) depending on the relative position to the opacity control and on the current zoom settings

Parameters:

	point	Absolute position of mouse cursor
	xPos	Density (0-4095)
	yPos	Opacity (0-1.0)
	zoomFaktorX
	zoomFaktorY

void TFEditDialog::OnBnClickedButtonclose

(

)

Close Button. Hide Dialog

BOOL TFEditDialog::OnInitDialog

(

)

[protected, virtual]

void TFEditDialog::OnLButtonDblClk	(	UINT	nFlags,
		CPoint	point
	)

Left mouse button double click. Add a point to the transfer function

void TFEditDialog::OnLButtonDown	(	UINT	nFlags,
		CPoint	point
	)

Left mouse button click. Drag and Drop points

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

Left mouse button release. End of drag and drop

void TFEditDialog::OnMouseMove	(	UINT	nFlags,
		CPoint	point
	)

Mouse movement. Move transfer function point when left mouse button is pressed and mouse was on a transfer function point

void TFEditDialog::OnPaint

(

)

Redraw Transfer function

LRESULT TFEditDialog::OnRangeChange	(	WPARAM	wParam,
		LPARAM	lParam
	)

Callback function for zoom sliders.

void TFEditDialog::OnRButtonUp	(	UINT	nFlags,
		CPoint	point
	)

Right mouse button release. Remove point, when mouse is on a opacity or color transfer function point

void TFEditDialog::RedrawColorAndOpacity

(

)

[private]

Update the color and opacity transfer function window on main screen and redraw 2D and 3D views. This method should be called when the transfer function has been changed
