What is the maximum image size that OpenCV can read when using:

img=cv2.imread('image.jpg')

P.S. Suppose I have enough RAM

So have a look in opencv code. I think memory is allocated at line 417 of matrix.cpp. After debugging I find everything is done in alloc.cpp. There are many #if in this file. In my configuration I use CV_USE_SYSTEM_MALLOC and memory allocation is done using malloc in function fastMalloc. There is two fastMalloc function .

In my configuration memory is limited by malloc If I want to know this limit I have to read VS 2013 doc and windows 10.

There is another limit height and width are of type Size.

Thank you for the effort. I will need to dive deeper into the hints you gave me
