Thinkphp5.0 image class library, what is the maximum picture size that this class library can open?

as shown in the question, what is the maximum size of this picture that can be opened? If you exceed this limit, what should you do with this oversized picture?
currently this picture is a picture as big as

the size of the picture that can be opened depends on your memory. The larger the process memory configuration of PHP, the larger the files you can open. Go and see how big the memory_limit configuration is in your php.ini.
