In plain english could someone explain each maketform, makresampler, and imtransform and how they work. If I am trying to make some transformation to an image, what can I do to obtain certain paramters. clear clc black = [0 0 0]'; a = .15; T = maketform('affine', [1 0 0; a 1 0; 0 0 1] ); A = imread('SI3_LAOSub_3600kx_Map_HAADF.tif'); h1 = figure; imshow(A); title('Original Image') R = makeresampler({'cubic','nearest'},'fill'); B = imtransform(A,T,R,'FillValues',orange); h2 = figure; imshow(B); title('Sheared Image');
This code works to effectively shear a lattice from not parallel to parallel. But im not sure why.

if true
% code
end
clc
black = [0 0 0]';
a = .15;
T = maketform('affine', [1 0 0; a 1 0; 0 0 1] );
A = imread('SI3_LAOSub_3600kx_Map_HAADF.tif');
h1 = figure; imshow(A); title('Original Image')
R = makeresampler({'cubic','nearest'},'fill');
B = imtransform(A,T,R,'FillValues',orange);
h2 = figure; imshow(B);
title('Sheared Image');
end
