is it possible to Load PDF page wise

[sterlingfordev]

Hi

we are using spire pdf to apply the watermark in microservice.
I have loaded a large pdf file (more than 1GB) and applied a watermark on all pages.
It is consuming more memory when loading and apply watermark

Is it possible to load and apply watermark batch by batch on single large file?

Note : input document is passing in stream format so i am using the LoadAsStream method

Hi，

Thank you for your inquiry.

For your requirements, I suggest a solution where you split your large PDF document into multiple PDF documents, add the watermark to each PDF document separately, and finally merge all the PDF documents into one document.

Here is the help documentation for splitting and merging PDF documents.
