size_t rows, cols; // These get set to the size of the images.
arma::mat maximalInputs, parameters, output;
MaximalInputs(parameters, maximalInputs);
ColumnsToBlocks(maximalInputs, outputs, rows, cols, true /* do scaling */, 0, 255);
data::Save("file.pgm", output);
If you want to specify rows and cols, then we would need some sort of interpolation algorithms(ex : bilinearInterpolation)
