		float *	array,
		float *	previousmarks,
		float *	newmarks,
		float	minvalue,
		float	maxvalue,
		float	index2mark
	)

This function creates a mask where it marks pixels with the same number based on a defined range of values.

void operaMarkPixbyCountRange(unsigned npixels, float *array, float *previousmark, float *newmark, float minvalue, float maxvalue, unsigned index2mark)

Note:

It keeps the previous mark mask values.

Parameters:

npixels	is an unsigned for the number of elements in the array
array	is a float pointer with the data
previousmarks	is a float pointer with the input badpixel mask data
newmarks	is a float pointer for the output mask
minvalue	is a float that defines the minimum data value to keep mask on (value=1)
maxvalue	is a float that defines the maximum data value to keep mask on (value=1)
index2mark	is an unsigned to mark values on the selected elements

Returns:

void
