Follow-up Comment #6, patch #9722 (project octave):
Two comments:
Matlab:
>> R = imref2d([100 200], 0.1, 0.4)
R =
imref2d with properties:
XWorldLimits: [0.0500 20.0500]
YWorldLimits: [0.2000 40.2000]
ImageSize: [100 200]
PixelExtentInWorldX: 0.1000
PixelExtentInWorldY: 0.4000
ImageExtentInWorldX: 20
ImageExtentInWorldY: 40
XIntrinsicLimits: [0.5000 200.5000]
YIntrinsicLimits: [0.5000 100.5000]
Octave:
>> R = imref2d([100 200], 0.1, 0.4)
R =
imref2d with properties:
XWorldLimits: [0.05 10.05]
YWorldLimits: [0.2 80.2]
ImageSize: [100 200]
PixelExtentInWorldX: 0.1
PixelExtentInWorldY: 0.4
ImageExtentInWorldX: 10
ImageExtentInWorldY: 80
XIntrinsicLimits: [0.5 200.5]
YIntrinsicLimits: [0.5 100.5]
it seems that m and n have swapped places in lines 111-112.
>> R = imref2d([100 200], [1.5 0.5], [2.5 0.5])
Matlab throws error because xWorldLimits(2) should be greater than
xWorldLimits(1) (and of course, the same for yWorldLimits)
