Detailed Description

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

Aim: Export a 2D and a 3D Image using the Netpbm PGM formats (ASCII mode).

Description of template struct 'PGMWriter'

• PGM: grayscale
• PGM3D: 3D variant of PGM

A functor can be specified to convert image values to PGM values (unsigned char).

Usage example:

...
typedef SpaceND<int,2> TSpace;
typedef TSpace::Point Point;
typedef HyperRectDomain<TSpace> Domain;
typedef ImageSelector<Domain, unsigned char>::Type Image;
...
Point a ( 1, 1);
Point b ( 16, 16);
Image image(a,b);
... //Do something in image
PGMWriter<Image>::exportPPM("export.pgm",image);

Template Parameters

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

static

Export an Image with PGM format.

Parameters

filename	name of the output file
aImage	the image to export
aFunctor	functor used to cast image values
saveASCII	used to save image with ASCII pixel value and with white space. (default= false since ASCII mode is not efficient).
topbotomOrder	'true' if the image scan should start from the top.

Returns

true if no errors occur.

static

Export an Image with PGM3D format.

Parameters

filename	name of the output file
aImage	the image to export
aFunctor	functor used to cast image values
saveASCII	used to save image with ASCII pixel value and with white space. (default= false since ASCII mode is not efficient).

Returns
