%RESIZEM Mapping for resizing object images in datasets and datafiles
%(outdated, replaced by im_resize)
%
% B = RESIZEM(A,SIZE,METHOD)
% B = A*RESIZEM([],SIZE,METHOD)
%
% INPUT
% A Dataset or datafile
% SIZE Desired size
% METHOD Method, see IMRESIZE
%
% OUTPUT
% B Dataset or datafile
%
% DESCRIPTION
% The objects stored as images in the dataset or datafile A are resized
% using the IMRESIZE command. Default METHOD is 'nearest' (nearest neighbor
% interpolation. In SIZE the desired output size has to be stored. Note
% that for proper use in PRTools third size parameter of multi-band images,
% e.g. 3 for RGB images, has to be supplied.
