LoadFromFile memory efficient options

[aellawaai]

Hi,

In our application we regularly have to load large files (> 500 MB) and I'm investigating memory efficient options in Spire.PDF.

Currently we use the LoadFromFile function.

Could you please recommend how to avoid that we need to hold the document wholly in memory?
Is there a method for loading single pages rather than the full document for example?
Or an option to specify if the file will be loaded into memory or not?

Thank you in advance!

Cheers

Hello,

Thanks for your inquiry!

Kindly note that we need the entire data of the PDF document to analyze it when loading the PDF through Spire.PDF. Sorry that it is impossible to load a single page, and we do not have an option to specify if the file will be loaded into memory when using our Spire.PDF. Hope you can understand.

But after you finished all operation about the PDF, you can use PdfDocument.Dispose() to release the memory that cost for loading.

Sincerely,
Marcia
