template<class T >

SurveyPxbImage::count_t SurveyPxbImageReader< T >::read	(	std::ifstream &	infile,
		measurements_t &	measurements,
		SurveyPxbImage::count_t	reserve = 830
	)		[inline]

Reads a file, parses its content and fills the data vector All data after a hash sign (#) is treated as a comment and not read

Parameters:

filename	Filename of the file to be read
measurements	Vector containing the measurements, previous content will be deleted
reserve	Initial size of the vector, set with vector::reserve()

Returns:

number of succesfully read entries
