Error : warpingFourPoints method

[fridezlucas]

Hi !

I use image-js to compute a warping 4 points image transformation. When I used this method, I always receive the error "pts muste be an array of 4 elements".

How to fix it

I check in the sources and I see that the param pts is an object like this :

pts: {
    pts: [[0,0], [100,0], [0, 100], [100, 100]]
};

You'll need to unwrap pts in an object and method will work !

Seems to me the parameter pts is an array of 4 XY as in this testcase

Not sure I understand what is the problem.
