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

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

Parameters
filenamename of the output file
aImagethe image to export
compressedboolean to decide wether the vol must be compressed or not
aFunctorfunctor used to cast image values
Returns
true if no errors occur.

)
inlinestaticprivate

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

Parameters
outsoutput stream.
valuevalue to write.
Returns
modified stream.
