Thank you !

Hi,

You can only merge existing pdf creating output images content PDF mixing the gdviewer & the imaging classes of the GdPicture Pro SDK .


I give you a simple visual basic function to merge 2 pdf :

How can I get this to work with GdPicture.NET?

For GdPicture.NET see: viewtopic.php?t=1583

Hello, I am having an "Out of Memory" error when I try to open the resulting file in Acrobat X. What should I be looking at?
I work in PowerBuilder11.5 and this is my code:
//------------------------------------------
inv_imaging.PdfNewPdf (as_dst_pdf, "Title", "Creator", "Author", "Producer")
inv_imaging.PdfSetMeasurementUnits(2)

ll_font = inv_imaging.PdfAddFont("Arial")
ll_image = inv_imaging.PdfAddImageFromFile(as_pic_file)
ll_width = inv_imaging.PdfGetImageWidth(ll_image)
ll_height = inv_imaging.PdfGetImageHeight(ll_image)
inv_imaging.PdfSetPageDimensions(ll_width + 5, ll_height + 5)
rc = inv_imaging.PdfNewPage()
inv_imaging.PdfDrawText(5, 10, "Arial Text Size 7", ll_font, 7)
inv_imaging.PdfDrawImage(ll_image, 1, 1, ll_width, ll_height)
inv_imaging.PdfEndPage()

inv_imaging.PdfSavePdf()

//----------------------------------------

Actually, now I am getting the same problem when trying to use it with c#:
//--------------------------------------
using System;
using System.Collections.Generic;
using System.Text;
using System.Xml;
using System.Security;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string ls_src_pdf, ls_dst_pdf, ls_src_pic, ls_args;
int ll_image;
XmlDocument ls_xml = new XmlDocument();

ls_args = "<Root><SourcePDF></SourcePDF><SourcePic>.\\test.jpg</SourcePic>";
ls_args += "<DestPDF>.\\reg_card_78582_1_signed.pdf</DestPDF></Root>";
ls_xml.InnerXml = ls_args;

ls_src_pdf = ls_xml.DocumentElement.ChildNodes[0].InnerText;
ls_src_pic = ls_xml.DocumentElement.ChildNodes[1].InnerText;
ls_dst_pdf = ls_xml.DocumentElement.ChildNodes[2].InnerText;

GdPicturePro5.cImaging ln_imaging = new GdPicturePro5.cImaging();
ln_imaging.SetLicenseNumber("XXXXXX");
ln_imaging.PdfNewPdf(ls_dst_pdf);
ll_image = ln_imaging.PdfAddImageFromFile(ls_src_pic);
ln_imaging.PdfSetMeasurementUnits(1);

ln_imaging.PdfNewPage();
ln_imaging.PdfSetPageDimensions(200, 150);
if (ll_image != 0)
{
ln_imaging.PdfDrawImage(ll_image, 100, 100, 30, 25);
}
ln_imaging.PdfEndPage();

ln_imaging.PdfSavePdf();



}
}
}

Code: Select all

Sub Merge2PDF(sInPDFPath1 As String, sInPDFPath2 As String, sOutPDFpath As String)
  Dim nCpt As Long
  Dim nPDFID As Long
  Dim nImageCount As Long
  Dim GdViewer1 As Object, Imaging1 As Object
 
  Set GdViewer1 = CreateObject("gdpicturepro5.gdviewer")
  Set Imaging1 = CreateObject("gdpicturepro5.imaging")
 
  GdViewer1.SetLicenseNumber ("LICENSE KEY")
  Imaging1.SetLicenseNumber ("LICENSE KEY")
 
  Imaging1.PdfNewPdf (sOutPDFpath)
  GdViewer1.LockControl = True
  nImageCount = 0

  GdViewer1.DisplayFromPdfFile (sInPDFPath1)
  For nCpt = 1 To GdViewer1.PageCount
      GdViewer1.DisplayFrame (nCpt)
      If Imaging1.PdfAddImageFromGdPictureImage(GdViewer1.GetNativeImage) <> 0 Then
         nImageCount = nImageCount + 1
      End If
  Next nCpt
  GdViewer1.CloseImage
 
  GdViewer1.DisplayFromPdfFile (sInPDFPath2)
  For nCpt = 1 To GdViewer1.PageCount
      GdViewer1.DisplayFrame (nCpt)
      If Imaging1.PdfAddImageFromGdPictureImage(GdViewer1.GetNativeImage) <> 0 Then
         nImageCount = nImageCount + 1
      End If
  Next nCpt
  GdViewer1.CloseImage
 
  For nCpt = 1 To nImageCount
      Call Imaging1.PdfSetPageDimensions(Imaging1.PdfGetImageWidth(nCpt), Imaging1.PdfGetImageHeight(nCpt))
      Imaging1.PdfNewPage
      Call Imaging1.PdfDrawImage(nCpt, 0, 0, Imaging1.PdfGetImageWidth(nCpt), Imaging1.PdfGetImageHeight(nCpt))
      Imaging1.PdfEndPage
  Next nCpt
 
  Imaging1.PdfSavePdf
 
  Set GdViewer1 = Nothing
  Set Imaging1 = Nothing
End Sub

If you need to merge two PDF files, here are some handy tips: First, check out online tools like Smallpdf or PDF Merge – they're super easy to use and don't require any software downloads. Before you merge, make sure your files are in the right order so everything flows smoothly. If you want more control over the process, you can try software like Adobe Acrobat for extra features. With these tips, merging PDFs should be a breeze!
