Detailed Description

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

Aim: Raw binary export of an Image.

Description of template struct 'RawWriter'

The export methods exportRaw8, exportRaw16 and exportRaw32 write raw files (little-endian format) with unsigned integer values of, respectively, 8 bits, 16 bits and 32 bits width. The method exportRaw can write any type of values, signed integers, floating point types or even structures.

A functor can be specified to convert image values to raw values (e.g. unsigned char for exportRaw8).

Example usage:

...
typedef DGtal::SpaceND<int,3> Space;
typedef DGtal::HyperRectDomain<Space> Domain;
typedef Domain::Point Point;
//Default image container = STLVector
typedef DGtal::ImageSelector<TDomain, unsigned char>::Type Image;
Domain domain( Point::diagonal(0), Point::diagonal(10) );
Image image( domain );
... // Filling the image.
DGtal::RawWriter<Image> writer;
if ( writer.exportRaw8( "data.raw", image ) )
trace.info() << "Image successfully exported." << endl;
else
trace.info() << "Error while exporting image." << endl;
