Insert page from other doc at specified index

Sat Dec 05, 2015 6:43 pm

Hello,

I have the following situation:
1 PDF with 1 page -> disclaimer, call it Y
1 PDF with different number of pages (1, 2, ... 10) -> invoice, call it X

I would like to insert the page from the first PDF (disclaimer) into the second PDF (invoice) at a specified index (index 1). I can only find a method to Append the page at the end of bigger PDF.
I did find a rearrange method, but I can't handle the possible different number of pages?

In short:
disclaimer: Y
invoice: X X X X X X
final doc: X Y X X X X X <- what to do to have this resulting doc?

Any easy method for this?

I thank you a lot in advance for your kind help.

Kind regards,

Hi,

Thanks for your inquiry.
Share sample code:

Code: Select all: PdfDocument doc1 = new PdfDocument(); doc1.LoadFromFile("..\\..\\disclaimer.pdf"); PdfDocument doc2 = new PdfDocument(); doc2.LoadFromFile("..\\..\\invoice.pdf"); PdfPageBase page = doc1.Pages[0]; SizeF size = page.Size; PdfPageBase newPage = doc2.Pages.Insert(1, size); newPage.Canvas.DrawTemplate(page.CreateTemplate(),new PointF(0,0)); doc2.SaveToFile(output);

Hello,

Thanks for your input! But it doesn't work.
I have the following code now:

Code: Select all: PdfDocument doc = new PdfDocument(); doc.LoadFromFile(filename); PdfDocument voorwaarden = new PdfDocument(); voorwaarden.LoadFromFile(filename_voorwaarden); /*****************************************/ /**** append disclaimer on page 2 *******/ /*****************************************/ PdfPageBase page = voorwaarden.Pages[0]; SizeF size = page.Size; PdfPageBase newPage = doc.Pages.Insert(1, size); newPage.Canvas.DrawTemplate(page.CreateTemplate(), new PointF(0, 0)); doc.SaveToFile("D:\\test.pdf");

If I have an invoice of 2 pages, it still adds the disclaimer (voorwaarden in Dutch) at the end of the document.
I really must oversee something...

Hi,

I tested your code and it worked, attached test files. I was using Spire.PDF Pack(Hot Fix) Version:3.5.143. Please try the version.

Code: Select all: PdfDocument invoiceD = new PdfDocument(); invoiceD.LoadFromFile(invoice); PdfDocument disclaimerD = new PdfDocument(); disclaimerD.LoadFromFile(disclaimer); /*****************************************/ /**** append disclaimer on page 2 *******/ /*****************************************/ PdfPageBase page = disclaimerD.Pages[0]; SizeF size = page.Size; PdfPageBase newPage = invoiceD.Pages.Insert(1, size); newPage.Canvas.DrawTemplate(page.CreateTemplate(), new PointF(0, 0)); invoiceD.SaveToFile(output);

If the issue still exists, please share your pdf files.

Hello,

I'm using FreeSpire.PDF v3.2. Found in the MS VS 2015 Nuget Package Manager. Should that work too?

Thanks for your response.

Hi,

Sorry that Free Spire.PDF v3.2 has some limitations on the function. Spire.PDF Pack(Hot Fix) Version:3.5.143 works fine in the case.

Except it isn't free or it shows a red text on top of the page?

Coding the logic for page reordering can be a bit of a headache, especially with complex document structures. While you're debugging your implementation, I've found https://www.thetoolapp.com/rearrange-pdf-pages/ really helpful for quickly verifying what the final output should look like or for fixing a small batch manually without having to re-run the whole script. It's a nice little shortcut to have in the toolkit.
