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.
How little memory must this fit in?
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?
How far in to 600 do you get?
I'm not sure but to save each hundred slides would be to write a new
workbook. You would then have to merge those into a single workbook via
poi unless you are prepared to merge the underlying xml files? That
approach would certainly be more memory efficient but more a xerces
problem than a poi problem.

Since no one really wants to sit through 600 slides, break the total up in
“chapters” and see where that gets you?
How much memory does you machine have, which version of java are you using.

Hello
I'm trying to generate a pptx file using the poi library.
The XMLSlideShow class contains about 600 XSLFSlides.
Each XSLFSlide object uses about 3mb of memory. 1.8gb of memory is required to
create one pptx file.
It uses out too much memory, causing an out of memory error.
And I can't increase the heap memory size.
Is there a way to save slides in multiple times in one pptx file?
Is there a way to reduce memory usage?
Thanks in advance.
