| Post subject: | Copy and resize document and fit it into box | ||
Hi, I'm using PDFSharp to create PDF. Now I trying to copy other document/image (PDF format with A3 size) and paste it in the box (x,y) in the new document (A4 size). In the new document, there will be have image details box and image box. So, how do I copy the image from other PDF into the image box in the new document? I also attach the sample I need to create using PDFSharp. Thanks.

Hi! You can draw pages from other PDF files like you draw images - draw them anywhere at any angle and any size. You may have to do some calculations to maintain the aspect ratio. See the Two Pages on One sample: http://pdfsharp.net/wiki/TwoPagesOnOne-sample.ashx Lines 40 and 54 draw PDF pages. Check the lines above for prerequisites. |

Now I'm stuck at Line 21 Code: XPdfForm form = XPdfForm.FromFile(filename); I got below error. Code: ArgumentException: The specified file has no valid PDF file header. Parameter name: path I already check the pdf, it not set as read-only files. Even I follow straight away, copy the file and remove Read-Only attr, but still got the error. It should be okay to read the files.  Here below is my code: Code: var filename = "sample.pdf";
var file = Path.Combine(Directory.GetCurrentDirectory(), filename); File.Copy(Path.Combine("../MyPDFSourceFolder/", filename), file, true); File.SetAttributes(file, File.GetAttributes(file) & ~FileAttributes.ReadOnly); var form = XPdfForm.FromFile(file); |

Hi! PDF files start with a header like "%PDF-1.4%". These should be the first bytes in the file. It seems your file does not have this header. |

I already check my pdf, it got %PDF-1.3.% but got those error. Even I try other pdf got from ADOBE site, still got this error - %PDF-1.4.%. https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf |
