Deleting text from PDF - TextReplaceOptions.ReplaceAdjustment.None not working

Aspose.PDF Product Family
#1

Hello,

I have got trouble deleting text from pdf document.
This is problematic file: Plik.pdf (824.4 KB)
This file contain dwo annotations. When I deleted annotation text (and annotation), the remaining text in line has shifted. (TextReplaceOptions.ReplaceAdjustment = NONE).

This is sample code how I deleting text:

        // textFragmentsAsRectangles from annotation
        for (int i = textFragmentsAsRectangles.Count - 1; i >= 0; i--)
        {
            var rectangle = textFragmentsAsRectangles[i];

            TextSearchOptions textOptions = new TextSearchOptions(rectangle, false);
            TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber(phrase: null, textOptions);
            textFragmentAbsorber.TextReplaceOptions.ReplaceAdjustmentAction = TextReplaceOptions.ReplaceAdjustment.None;

            try
            {
                page.Accept(textFragmentAbsorber);
            }
            catch
            {
                continue;
            }

            foreach (var textFragment in textFragmentAbsorber.TextFragments)
            {
                // The property (textFragment.Text) contains good text (highlighted in document)
                textFragment.Text = string.Empty;
            }

Summary: in sample document “TextReplaceOptions.ReplaceAdjustment.None” option not working for all text in document (There are place where this option works well).

Hi there, we are having a very similar issue to this with the Aspose PDF library and have tried the most recent build (22.3.)

We have customers who are looking for this functionality and would like to know where this might be in the bug fix pipeline. We would consider going down the paid support route if that would resolve the issue more quickly.

Please advise.

Sometimes, issues are related to specific PDF document and are resolved only for that particular document. Can you please share any sample PDF document from your side along with the code snippet that you are trying and facing an issue? We will separately log a ticket for your case and share the ID with you. And sure, using the paid support option will definitely expedite the issue investigation and resolution process and you will receive updates quickly.

Hi Asad, thanks for your reply - the reason I was following up is because I received an email from Aspose support, offering tips to get started. I was concerned that my original comment and concerns were not picked up but you have now confirmed that this is not the case.

I look forward to hearing from you.

kind regards,

Greg.
