Detailed Description

Implementation of OutputFileFormat paradigm for the ECAT7 format.

Warning: Currently output always uses 2-byte signed integers in big-endian byte order.

Member Function Documentation

◆ set_type_of_numbers()

NumericType stir::ecat::ecat7::ECAT7OutputFileFormat::set_type_of_numbers	(	const NumericType &	new_type,
		const bool	warn = `false`
	)

virtual

Set type of numbers to be used for output.

Currently the return value will always be NumericType::SHORT

Reimplemented from stir::OutputFileFormat< DiscretisedDensity< 3, float > >.

References stir::warning().

◆ set_byte_order()

ByteOrder stir::ecat::ecat7::ECAT7OutputFileFormat::set_byte_order	(	const ByteOrder &	new_byte_order,
		const bool	warn = `false`
	)

virtual

Set byte order to be used for output.

Currently the return value will always be ByteOrder::BIGENDIAN

Reimplemented from stir::OutputFileFormat< DiscretisedDensity< 3, float > >.

References stir::warning().

◆ actual_write_to_file()

Succeeded stir::ecat::ecat7::ECAT7OutputFileFormat::actual_write_to_file	(	std::string &	filename,
		const DiscretisedDensity< 3, float > &	density
	)		const

protectedvirtual

virtual function called by write_to_file()

This function has to be overloaded by the derived class.

The reason we do not simply make write_to_file() virtual is that we have 2 versions of write_to_file. C++ rules are such that overloading the virtual function in a derived class means that the other version gets hidden. Having the non-virtual write_to_file() call the virtual actual_write_to_file() solves this problem.

Implements stir::OutputFileFormat< DiscretisedDensity< 3, float > >.

References stir::add_extension(), stir::ecat::ecat7::DiscretisedDensity_to_ECAT7(), stir::ecat::ecat7::make_ECAT7_main_header(), and stir::warning().

◆ post_processing()

bool stir::ecat::ecat7::ECAT7OutputFileFormat::post_processing ( )

protectedvirtual

This will be called at the end of the parsing.

Returns: false if everything OK, true if not

Reimplemented from stir::ParsingObject.
