Cannot open attachments embeded using GDPicture

[Halla602]

Hi, I recently encountered this weird problem.
When I embed random files into pdf, sometimes I cannot open the first file when displaying the .pdf using Adobe Acrobat.

What's weird, when I change the names of attachments (since acrobat shows the attachment list alphabetically ordered), the same file that couldn't be opened has no problems at all. Files I use stay the same, just names change.

So, in this example when I name the files named thusly, I get no errors:

Code: Select all

Plain text only.eml
test.rtf
zchilipepper.jpg

But when I name them this way, the image file cannot be opened:

Code: Select all

chilipepper.jpg
Plain text only.eml
test.rtf

My code for embeding files into pdf

Code: Select all

              Output_PDF.LoadFromStream(new MemoryStream(Input_PDF_Data));
              string[] Files = Directory.GetFiles(Temp_Attachements_Dir);
              for (int i = 0; i < Files.Length; i++)
              {
                Output_PDF.EmbedFile(Files[i], Path.GetFileName(Files[i]), "");
                File.Delete(Files[i]);
              }
              Stream stm = (Stream)new MemoryStream();
              Output_PDF.SaveToStream(stm);
              Output_PDF_Data = ((MemoryStream)stm).ToArray();

Thank you for your response,

Hi,

The problem has been reproduced.
Inside the PDF the names should have been sorted but were not. The problem has been fixed and will be available in the next minor release, until then, a work around consists of adding the files in Alhabetical order. something like:

Code: Select all

string[] Files = Directory.GetFiles(Temp_Attachements_Dir);
Array.Sort(Files , StringComparer.Ordinal); 
for (int i = 0; i < Files.Length; i++)

Hope this help,
Jean-Luc
