Detailed Description

template<typename TImage, typename TFunctor = functors::Identity>
struct DGtal::LongvolWriter< TImage, TFunctor >

Aim: Export a 3D Image using the Longvol formats (volumetric image with DGtal::uint64_t value type).

Description of template struct 'LongvolWriter'

A functor can be specified to convert image values to LongVol values (DGtal::uint64_t).

Template Parameters

TImage	the Image type.
TFunctor	the type of functor used in the export.

static

Export an Image with the Longvol format. A DGtal::IOException is thrown in case of io problems.

Parameters

filename	name of the output file
aImage	the image to export
compressed	boolean to decide wether the vol must be compressed or not
aFunctor	functor used to cast image values

Returns

true if no errors occur.

template<typename Word>

std::ostream & DGtal::LongvolWriter< TImage, TFunctor >::write_word ( std::ostream & outs, Word value )

inlinestaticprivate

Generic write word (binary mode) in little-endian.

Parameters

outs	output stream.
value	value to write.

Returns

modified stream.
