Thank you for your reply. I am using oracle jdk1.8. But I do not want to increase heap memory. I want to find a solution in another way.
What does "chpaters" you mean? For example, does it mean to divide into 100 slides and save each file? I do not want to save as multiple files. I want to save all slides in one file. For example, I'm considering flushing slides to a file every 100 slides created. Is this possible using the poi library?
