iTextSharp中的PDF大小上限

Question

i have encountered a problem maximum page size allowed in iTextsharp, so when i try to generate a document with size superior to 14 400 , i get an message error the.page.size.must.be.smaller.than.14400.by.14400.its.1.by.2 , i tried to play with userunits like described here , but i have not found a solution.

i generate the PDF by merging file in one page using AddTemplate() , i think to scale the pdf dimensions by 1/4 for eg, and set userunits to 4, but i think that i should scale the imported pages too , any help in this way because i don't know how to scale imported pages, i not sure if this the right solution.

 PdfImportedPage imp1 = wr.GetImportedPage(r1, 1); 
 wr.DirectContent.AddTemplate(imp1,(float)(x*cm),(float)(y*cm));

Any help please or any suggestion

Answer 1

As you make clear in your comment that your problem in testing your solution ( DirectContent.AddTemplate applied to a PdfImportedPage ) actually is that you don't know how to scale imported page , here a pointer to an example that shows how to do right that.

Have a look at the sample NUpTool.cs translated from the matching Java sample NUpTool from chapter 6 of iText in Action — 2nd Edition . The variable factor here describes the scaling factor.
