Spacing changes after changing case

Often but less often than not, when changing the case of letter, the spacing spacing after the new now lower case letter is shrunk and the right letter almost touches the previous letter.

Does the entire text fragment need to be replaced with a new textfragment to recalculate the appropriate spacing? If so I don’t see a TextFragment.Remove function or anything in the Page document.

Thank you for contacting support.

Please note that the text fragments with keywords contain some other text and for replacing only the keywords without related text, we should set TextReplaceOptions.ReplaceAdjustment.None as under:

TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber("XYZ");
TextReplaceOptions objTextReplaceOptions = new TextReplaceOptions(TextReplaceOptions.ReplaceAdjustment.None)
{
    ReplaceAdjustmentAction = TextReplaceOptions.ReplaceAdjustment.None
};
textFragmentAbsorber.TextReplaceOptions = objTextReplaceOptions;

If you still face the problem while using Aspose.PDF for .NET 19.3 then please share narrowed down code snippet along with source and generated files so that we may investigate further to help you out.

I made the chance and noticed some difference in my modified docs however I still see my lower case t smashed up against the next letter.

Here’s the basics:

TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber();
TextReplaceOptions objTextReplaceOptions = new TextReplaceOptions(TextReplaceOptions.ReplaceAdjustment.None)
{
ReplaceAdjustmentAction = TextReplaceOptions.ReplaceAdjustment.None
};
textFragmentAbsorber.TextReplaceOptions = objTextReplaceOptions;

        document.Pages.Accept(textFragmentAbsorber);
        TextFragmentCollection textFragmentCollection = textFragmentAbsorber.TextFragments;

        foreach (TextFragment textFragment in textFragmentCollection)
        {
            textFragment,Text.Replace("Trade", "trade");
        }

Would you please share source and generated files so that we may try to reproduce and investigate it further.

Here are the files. Notice the lower case ‘t’ is kissing the next letter. Also the annotations are using the rectangles for each character in the modified TextFragment. It seems the rectangle is off. Sometimes it overlaps the next character.

We have noticed the difference in your PDF documents but shared data is not reproducing the issue in our environment. The code snippet generates identical PDF document so kindly review the code and ensure sharing SSCCE code so that we may proceed to assist you accordingly. We appreciate your cooperation in this regard.

Farhan, please try with the code below using this file:

You will notice the lower case t is now kissing the r.
