How to split large PDF document into multiple different ranges.

We can split the PDF document into multiple different ranges by importing pages into the new document based on the specified range. Please find the code snippet and sample link below.

// Sets the different ranges to split the PDF document.
int[] SplitArray = new int[] { 3, 5, 4 };
 
// Loads the document.
PdfLoadedDocument ldoc = new PdfLoadedDocument("input.pdf");
int startIndex = 0;
int endIndex= 0;
for (int i = 0; i < SplitArray.Length; i++)
{
    endIndex += SplitArray[i];
     // Creates a new PDF document.
    PdfDocument doc = new PdfDocument();
     // Imports the pages into the new PDF document.
    doc.ImportPageRange(ldoc, startIndex, endIndex - 1);
     startIndex = endIndex;
     // Saves the document.
    doc.Save(i.ToString() + ".pdf");
     // Closes the document.
    doc.Close(true);
}
ldoc.Close(true);
