How to reduce memory usage while merging PDF documents

How to reduce memory usage while merging the PDF documents?

The memory usage can be reduced by using EnableMemoryOptimization property. Please find the code example and sample below for the same.

C#:

 

//Input PDF documents.

string[] inputDocuments = Directory.GetFiles(@"..\..\Data\","*.pdf");

//Create a new instance.

PdfDocument document = new PdfDocument();

//Optimize memory while merging PDF documents.

document.EnableMemoryOptimization = true;

//Iterate input PDF documents.

foreach (string inputDocument in inputDocuments)

{

//Loads PDF document in order to merge.

PdfLoadedDocument loadedDocument = new PdfLoadedDocument(inputDocument);

loadedDocument.EnableMemoryOptimization = true;

//Merge loaded document contents to the parent PDF document.

document.ImportPageRange(loadedDocument, 0, loadedDocument.Pages.Count - 1);

//Close the document.

loadedDocument.Close(true);

}

//Save and close the document.

document.Save("Output.pdf");

document.Close(true);
