Member Function Documentation

ClearImage()

void DdtMagnificationWidget::ClearImage

(

)

Clears the imae display

DrawCenterRectangle()

void DdtMagnificationWidget::DrawCenterRectangle

(

QPixmap *const

image

)

const

Draw a rectangle around the center of the image Size depends on environment of the widget. For widget and dialog the size should be 10 x 10 pixels, for the Pick Object dialog, it depends on the position of the pixel-slider

Parameters

image

QPixmap onto which the rectangle is drawn

DrawMarker()

void DdtMagnificationWidget::DrawMarker	(	double	fwhm_x,
		double	fwhm_y,
		const double	angle_x_axis
	)		const

Draws a marker for a given position with given parameters

Parameters

fwhm_x	Full width at half maximum x
fwhm_y	Full width at half maximum y
angle_x_axis	Angle of marker

get_default_magnification_factors()

(

)

Retrieve the list of magnification scales

Returns

the list of scale factors

get_region_size()

int DdtMagnificationWidget::get_region_size

(

)

Retrieve the value region size
