Follow-up Comment #10, bug #44794 (project octave):
The test fails in Matlab (R2010b)
>> im = rand (2);
>> tmat = [eye(2); 0 0];
>> T = maketform ('affine', tmat);
>> im2 = imtransform (im, T, 'xdata', [1 3]);
??? Error using ==> imtransform>parse_inputs at 454
If either 'XData' or 'YData' is specified, then both must be specified.
Error in ==> imtransform at 264
args = parse_inputs(varargin{:});
but If I set Ydata, then:
>> im2 = imtransform (im, T, 'xdata', [1 3], 'ydata', [1 3])
im2 =
0.8147 0.1270 0
0.9058 0.9134 0
0 0 0
>> im2 = imtransform (im, T, 'xdata', [1 3], 'ydata', [1 2])
im2 =
0.8147 0.1270 0
0.9058 0.9134 0
This sounds about right to me but you're more familiar with this function.
