Member Function Documentation

DiMonoModality* DiMonoPixel::addReferenceToModality ( )

add a reference to the internally managed modality transform object

Returns:: pointer to modality transform object (might be NULL)

double DiMonoPixel::getAbsMaximum ( ) const [inline]

get absolute maximum pixel value.

The result depends on former transforms.

Returns:: absolute maximum value

double DiMonoPixel::getAbsMaxRange ( ) const [inline]

get absolute pixel range

Returns:: absolute pixel range

double DiMonoPixel::getAbsMinimum ( ) const [inline]

get absolute minimum pixel value.

The result depends on former transforms.

Returns:: absolute minimum value

unsigned int DiMonoPixel::getBits ( ) const [inline]

get number of bits per pixel

Returns:: number of bits

virtual int DiMonoPixel::getHistogramWindow	(	const double	thresh,
		double &	center,
		double &	width
	)		`[pure virtual]`

get automatically computed histogram window (abstract)

Parameters:

thresh	ignore certain percentage of pixels at lower and upper boundaries
center	reference to storage area for window center value
width	reference to storage area for window width value

Returns:: status, true if successful, false otherwise

Implemented in DiMonoPixelTemplate< T >, and DiMonoPixelTemplate< T3 >.

virtual int DiMonoPixel::getMinMaxValues	(	double &	min,
		double &	max
	)		const `[pure virtual]`

get minimum and maximum pixel values (abstract)

Parameters:

min	reference to storage area for minimum pixel value
max	reference to storage area for maximum pixel value

Returns:: status, true if successful, false otherwise

Implemented in DiMonoPixelTemplate< T >, and DiMonoPixelTemplate< T3 >.

virtual int DiMonoPixel::getMinMaxWindow	(	const int	idx,
		double &	center,
		double &	width
	)		`[pure virtual]`

get automatically computed min-max window (abstract)

Parameters:

idx	ignore global min/max pixel values if > 0
center	reference to storage area for window center value
width	reference to storage area for window width value

Returns:: status, true if successful, false otherwise

Implemented in DiMonoPixelTemplate< T >, and DiMonoPixelTemplate< T3 >.

const char* DiMonoPixel::getModalityLutExplanation ( ) const [inline]

get modality LUT explanation string

Returns:: modality LUT explanation

int DiMonoPixel::getPlanes ( ) const [inline, virtual]

get number of planes

Returns:: number of planes (here 1, monochrome)

Implements DiPixel.

virtual int DiMonoPixel::getRoiWindow	(	const unsigned long	left_pos,
		const unsigned long	top_pos,
		const unsigned long	width,
		const unsigned long	height,
		const unsigned long	columns,
		const unsigned long	rows,
		const unsigned long	frame,
		double &	voiCenter,
		double &	voiWidth
	)		`[pure virtual]`

get automatically computed Region of Interest (ROI) window (abstract)

Parameters:

left_pos	x-coordinate of the top left-hand corner of the ROI (starting from 0)
top_pos	y-coordinate of the top left-hand corner of the ROI (starting from 0)
width	width in pixels of the rectangular ROI (minimum: 1)
height	height in pixels of the rectangular ROI (minimum: 1)
columns	number of columns (width) of the associated image
rows	number of rows (height) of the associated image
frame	index of the frame to be used for the calculation
voiCenter	reference to storage area for window center value
voiWidth	reference to storage area for window width value

Returns:: status, true if successful, false otherwise

Implemented in DiMonoPixelTemplate< T >, and DiMonoPixelTemplate< T3 >.

int DiMonoPixel::isPotentiallySigned ( ) const [inline]

check whether pixel data is 'potentially' signed.

This check is necessary to interpret possibly folowing LUT descriptors correctly (see supplement 33)

Returns:: true if pixel data is potentially signed, false otherwise
