int imgAbsMax	(	IMG *	img,
		float *	maxvalue
	)

Searches the max absolute pixel value in the IMG data. Sets maxvalue to the absolute max value with sign.

Parameters

img	image structure
maxvalue	pointer to output

Returns: 0 if ok, 1 invalid image status, 2 invalid output pointer, 3 invalid image dimensions

int imgFrameMinMax	(	IMG *	img,
		int	frame,
		float *	minvalue,
		float *	maxvalue
	)

Searches the min and max pixel value in one frame (1..dimt) of the IMG data.

Parameters

img	image structure
frame	frame number [1..number of frames]
minvalue	pointer to output of minimum
maxvalue	pointer to output of maximum

Returns: 0 if ok, 1 invalid image status, 2 invalid output pointer, 3 invalid image dimensions

int imgMinMax	(	IMG *	img,
		float *	minvalue,
		float *	maxvalue
	)

Searches the min and max pixel value in the IMG data.

Parameters

img	image structure
minvalue	pointer to output of minimum
maxvalue	pointer to output of maximum

Returns: 0 if ok, 1 invalid image status, 2 invalid output pointer, 3 invalid image dimensions

int imgReadMinMax	(	const char *	fname,
		float *	fmin,
		float *	fmax
	)

Read the calibrated maximum and minimum pixel values in the specified file in ECAT 7, ECAT 6.3, or Analyze 7.5 format. File is read frame-by-frame with normal IMG functions.

Parameters

fname	ECAT 7 or ECAT 6.3 filename, or Analyze 7.5 database
fmin	pointer to minimum pixel value that will be set by this function
fmax	pointer to maximum pixel value that will be set by this function

Returns: errstatus, which is STATUS_OK (0) when call was successful, and >0 in case of an error.

Here is the call graph for this function:

int imgSmoothMax	(	IMG *	img,
		float *	maxvalue
	)

Searches the spatially (3x3) smoothed max pixel value in the IMG data.

Parameters

img	image structure
maxvalue	pointer to output

Returns: 0 if ok, 1 invalid image status, 2 invalid output pointer, 3 invalid image dimensions
