Table Absorber - Absorbed table rows are merged in one

Aspose.PDF Product Family
1

Hi Team,

We recently purchased an Aspose.total license and are experiencing an issue with the Table absorber functionality. Despite having enough space between rows, all rows are merged into a single row. Please check this issue and provide a solution as soon as possible.

Could you share code you using to achieve described result?

Hi ilya,

Please see the attached document and c# code file that we used for the PDF table absorber. Please assist me in extracting the table from the document, with proper row separation.

Could you describe what result you expect from Table absorber output?
It seems that TableAbsorber extracts multiple rows as small tables and it doesn’t look like single row merge
coordinates of extracted TextFragments also seem correct

Hi @ilyazhuykov ,

Please see the attached document for the expected rows to extract from the document.

and write you as soon as there will be any news

@parthiveera
For now unfortunately I can’t exactly say when this issue will be resolved
I added it with maximum priority and mark of paid customer, so it should be prioritized by development team
If I found some workaround or there will be any news I’ll contact you as soon as possible

@parthiveera
I found workaround that could resolve your problem
Try the following code:

Aspose.Pdf.Text.TableAbsorber absorber = new Aspose.Pdf.Text.TableAbsorber();
absorber.UseFlowEngine = true;
absorber.Visit(page);

The output seems close to what you expected to get

Hi ilya.zhuykov,

We have already attempted this workaround, however we are not getting the intended results; all rows are coming in separately row by row. Please see my attached result from the table absorber.

Could you share version of Aspose.PDF you are using?
I tried on latest version the following code

var input = InputFolder + "table_sample.pdf";
Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(input);
foreach (Page page in pdfDocument.Pages)
{
    Aspose.Pdf.Text.TableAbsorber absorber = new Aspose.Pdf.Text.TableAbsorber();
    absorber.UseFlowEngine = true;
    absorber.Visit(page);
    foreach (AbsorbedTable table in absorber.TableList)
    {
        foreach (AbsorbedRow row in table.RowList)
        {
            Console.WriteLine("Row");
            Console.WriteLine();
            foreach (AbsorbedCell cell in row.CellList)
            {
                var fragments = cell.TextFragments.OrderBy(x => x.Position.XIndent);
                foreach (TextFragment fragment in fragments)
                {
                    string txt = "";
                    foreach (TextSegment seg in fragment.Segments)
                    {
                        txt += seg.Text;
                    }
                    Console.Write(txt);
                    Console.Write(" ");
                }
            }
            Console.Write(" ");
            Console.WriteLine();
        }
    }
}

and result differs from your version

Maybe it could be resolved by upgrading version
