Hi Tilal,

I too facing the same problem when trying to extract the pages from the PDF

Below is the sample code

static void Main(string[] args)
{
// load existing PDF file
Document pdfDocument = new Document(“sample5.pdf”);
// Create TableAbsorber object to find tables

TableAbsorber absorber = new TableAbsorber(); // Index out of range error occurring here

absorber.Visit(pdfDocument.Pages[2]);

foreach (var table in absorber.TableList)
{
foreach (var row in table.RowList)
foreach (var cell in row.CellList)
foreach (var txt in cell.TextFragments)
Console.WriteLine(txt.ToString());
}

}

Sample5.pdf is a multi page PDF with tables embedded

Thanks in Advance

Ravi

Hi Ravi,

Thanks for contacting support.

The Index Out Of Range exception occurs when you try to access the resource/page which does not exist in PDF document. During my my testing when I have tried accessing second page of PDF file which only had single page, similar error message is displayed. However from your above statement, the input/source file is multi-page, so it appears to be a document specific issue.

Can you please share the resource/input file which you are using, so that we can again test the scenario in our environment. We are really sorry for this inconvenience.

Hi Nayyer,

Thanks for your reply.

The below code which am using to visit the pages
// load existing PDF file
Document pdfDocument = new Document(“sample4.pdf”);
// Create TableAbsorber object to find tables

TableAbsorber absorber = new TableAbsorber();

absorber.Visit(pdfDocument.Pages[2]);

Am able to visit all the pages when am using Textfragmentabsorber. The issue is only when am using Tableabsorber.

Please find the attached pdf that i used for extracting the pages

Also please find the stack track below which i observed

Hi Ravi,

When using same code snippet with one of my sample files with simple Table instance, I am unable to notice any issue. However the issue appears when trying to extract table from complex PDF document. Nevertheless, the team will investigate the earlier reported issue and as soon as we have some further updates, we will let you know.
