Reading text and highlighting a text by cordinates

Aspose.PDF Product Family
1

Hi,

I am trying to highlight and get text using x, y coordinates. I can get the highlight working but i cannot seem to retrieve text.

var document = new Aspose.Pdf.Document(pdfStream);
var contentEditor = new Aspose.Pdf.Facades.PdfContentEditor();
contentEditor.BindPdf(document);
contentEditor.CreateMarkup(new System.Drawing.Rectangle(520, 714, 40, 10), “”, 0, 1, System.Drawing.Color.Yellow);
var absorber = new Aspose.Pdf.Text.TextAbsorber();
absorber.TextSearchOptions.LimitToPageBounds = true;
absorber.TextSearchOptions.Rectangle = new Aspose.Pdf.Rectangle(520, 714, 560, 715);
document.Pages[1].Accept(absorber);
string invoiceNumber = absorber.Text;

What am i doing wrong?

Thanks

We have investigated the issue and found an error in the source code:

new System.Drawing.Rectangle(520, 714, 40, 10) - correct rectangle 40x10 new Aspose.Pdf.Rectangle(520, 714, 560, 715) - incorrect rectangle 40x1 (with height of 1 pt)

We used the following code for testing:

var document = new Aspose.Pdf.Document(dataDir + "invoice_sample.pdf");
var contentEditor = new Aspose.Pdf.Facades.PdfContentEditor();
contentEditor.BindPdf(document);
contentEditor.CreateMarkup(new System.Drawing.Rectangle(520, 714, 40, 10), "", 0, 1, System.Drawing.Color.Yellow);
var absorber = new Aspose.Pdf.Text.TextAbsorber();
absorber.TextSearchOptions.LimitToPageBounds = true;
absorber.TextSearchOptions.Rectangle = new Aspose.Pdf.Rectangle(520, 714, 560, 724);
document.Pages[1].Accept(absorber);
string invoiceNumber = absorber.Text;
Console.WriteLine(absorber.Text);
document.Save(dataDir + "invoice_sample_out.pdf");

It finds the expected ‘13473’ text.
