Extract text with rectangle, the result has lots of break line

Aspose.PDF Product Family

Hi,
I want to copy the select text from pdf.
First I choose a Rectangle area and using its coordinates to init TextAbosrber.TextSearchOptions.Rectangle. and then I selected a page to accept this textAbsorber.
Finally, I found that the textAbsorber.Text has lots of break lines in the end. sometime it also will be displayed between each line.
here is sample code:

     var absorber = new TextAbsorber();
     absorber.TextSearchOptions.LimitToPageBounds = true;
     var ltPoint = CalculateSelectedAreaOnPage(SelectRectLeftTopPoint);
     var rbPoint = CalculateSelectedAreaOnPage(SelectRectRightBottomPoint);
     absorber.TextSearchOptions.Rectangle = (new Aspose.Pdf.Rectangle(ltPoint.X, ltPoint.Y, >rbPoint.X, rbPoint.Y));
     CurPreviewPage.Accept(absorber);
     string extractedText = absorber.Text;

Please ingore the function CalculateSelectedAreaOnpage(), it just a function to convert point.
Please help me check the extract text result. thanks.

Thanks for your replay,
Here.pdf (95.8 KB)
and a select the rectange such as SelectedRect.png (55.5 KB)
and the extracted text result is extractedTextResult.png (12.2 KB)
you can see I have selected all the text, so that you can see the extra breakline
sometimes linebreak will appear in line space, please check it.

Please try to use the code snippet as below in order to extract text without spaces:

Document doc = new Document(dataDir + "extractTextTextPDF.pdf");
TextAbsorber ta = new TextAbsorber();
ta.TextSearchOptions.Rectangle = (new Aspose.Pdf.Rectangle(71.250475, 485.250638, 543.749519, 425.250763));
ta.ExtractionOptions = new TextExtractionOptions(TextExtractionOptions.TextFormattingMode.Raw);
doc.Pages.Accept(ta);
string text = ta.Text;
