Question

Hi, currently I want to use the cv.warpAffine(img, transformMatrix, (224, 224), ...). I have the transformMatrix as an Array2d, my question is to convert the transformMatrix from Array2d and then can pass it into the cv.warpAffine function. Can you give me the solution for my problem. Thank you in advance.
