Merge Pages

[Safder]

How do i merge different PDF pages into one PDF file. in Spire.PDF for java.

Hi,

Thanks for your inquiry.
Do you want to merge selected pages from one PDF file or merge selected pages form multiple PDF files into one?

For case one, please refer to the code below.

Code: Select all

//merge selected pages from one PDF file
PdfDocument doc=new PdfDocument();
doc.loadFromFile("……\\……\\……\\filename.pdf");
PdfDocument doc1 = new PdfDocument();
doc1.insertPage(doc,0);
doc1.insertPage(doc,1);
doc1.saveToFile("output.pdf");

For case two, here is the code for your reference.

Code: Select all

//Merge selected pages from multiple PDF files into one
String[] files = new String[]
      {
              "……\\……\\……\\filename1.pdf",
              "……\\……\\……\\filename2.pdf",
              "……\\……\\……\\filename3.pdf",
};

PdfDocument[] docs = new PdfDocument[files.length];
for (int i = 0; i < files.length; i++)
{
    docs[i] = new PdfDocument(files[i]);
}

PdfDocument doc = new PdfDocument();
doc.insertPage(docs[0],0);
doc.insertPage(docs[1],1);
doc.insertPage(docs[2],3);

doc.saveToFile("output.pdf");
doc.close();

If my code couldn’t solve your issue, please offer us your input PDF files and describe your requirement in detail.

Hi,

Thanks for your reply.
You could merge your developed pages by creating templates then drawing these pages on them.
Below is the code for your reference.

Code: Select all

//get the pages you want to merge
PdfPageBase page1 = doc1.getPages().get(1);
Dimension2D size1=page1.getSize();

PdfPageBase page2=doc2.getPages().get(1);
Dimension2D size2=page2.getSize();

//Create templates then draw these pages on them
PdfPageBase newpage = doc.getPages().add(size1);
newpage.getCanvas().drawTemplate(page1.createTemplate(), new Point(0,0));

PdfPageBase newpage2=doc.getPages().add(size2);
newpage2.getCanvas().drawTemplate(page2.createTemplate(),new Point(0,0) );

If my code couldn’t solve your issue, please offer us your input PDF files(if any) and the complete code you were using for further investigation.
