Hi,

I am trying to change the text of PDF files using TextFragment.
textFragment.Text = “new text”;

Text gets replaced but I also want to retain its formatting like if the original text is Bold , new text should also be in bold. ( Or any other such cases like color and text styles. )

Hi Ruchi,


Thanks for contacting support.

In order to accomplish your requirement, you need to perform following steps.

  1. First search the particular text string which you need to replace.
  2. Get the current formatting information of TextFragment.
  3. Replace text string and use previously obtained formatting information for newly replaced string.

In case you still face any issue, please share the resource PDF file.

Hii,

I checked the links. This links contains information about setting the formatting.
But How to get this formatting information first ?
If I use same properties to get the information before replacing text, it says these properties lacks the get accessors.

Hi Ruchi,


Thanks for your feedback, In first link we are getting and printing text formatting of TextFragment. You may store the properties in some variables and can apply these to replaced text as stated in second link.

…<o:p></o:p>

float font=textFragment.TextState.FontSize;<o:p></o:p>

…<o:p></o:p>

…<o:p></o:p>

textFragment.TextState.FontSize = font;<o:p></o:p>

…<o:p></o:p>


Please feel free to contact us for any further assistance.

Font and FontSize properties are having getter and setter both , But FontStyle is having only setter.

Similarly forgroundColor property is having getter and setter both but backgroundColor have only setter.
Underline is also having only setter.
Is this done purposefully or you may fix this issue in next version.
