Aspose.pdf Evaluation Version

Hi There,

I am using free trial version of to generate pdf. I have a template pdf document added with placeholders and am trying to replace those with simple text replace logic of aspose.pdf api. But the layout of template and generated pdf is differing.

If my placeholder is center aligned with value as @Test.Item.Value, then the replacement happens from ‘@’ keyword and the final pdf has this text wrongly aligned i.e. to the left.
Also if the replaced word is smaller than placeholder then it leaves space after the word.
If @Test.Item.Value gets replaced with ‘hello’ then it adds spaces for remaining letters in placeholders.

So is it with trial version only? will it work fine with licensed copy?


Thanks for contacting support.

The only limitation of API trial version is that you can process only 4 elements as per any collection, which can be avoid by applying temporary license. However, as far as the issue which you are facing, is concerned, please share your sample PDF document along with the code snippet which you are using. We will test the scenario in our environment and respond you accordingly.

Using below code to replace the pdf text-

PdfContentEditor pdfContentEditor = new PdfContentEditor();
TextReplaceOptions options = new TextReplaceOptions(TextReplaceOptions.ReplaceAdjustment.AdjustSpaceWidth);
pdfContentEditor.TextReplaceOptions = options;


pdfContentEditor.ReplaceText("@Data.Person.Id", “1”);
pdfContentEditor.ReplaceText("@Data.Person.Name.Firstname", “test”);
pdfContentEditor.ReplaceText("@Data.Person.EmpType", “C”);
pdfContentEditor.ReplaceText("@Data.Person.Birthdate", “01 August 1999”);
pdfContentEditor.ReplaceText("@Data.Person.Birthdate.Day", “2”);
pdfContentEditor.ReplaceText("@Data.Person.Birthdate.Month", “August”);

Thanks for sharing sample document and code snippet.

We have tested the scenario in our environment and managed to reproduce the issue which you have stated. We have also tried a DOM based code snippet to replace the text from PDF like following but did not get much success.

Document pdfdocument = new Document(dataDir + "TemplatePdf.pdf");
TextFragmentAbsorber tfa = new TextFragmentAbsorber();
tfa.TextReplaceOptions.ReplaceAdjustmentAction = TextReplaceOptions.ReplaceAdjustment.None;
foreach(TextFragment tf in tfa.TextFragments)
  case "@Data.Person.Id":
   tf.Text = "1";
  case "@Data.Name.Firstname":
   tf.Text = "test";
  case "@Data.Person.EmpType":
   tf.Text = "C";
  case "@Data.Person.Birthdate":
   tf.Text = "01 August 1999";
  case "@Data.Person.Birthdate.Day":
   tf.Text = "2";
  case "@Data.Person.Birthdate.Month":
   tf.Text = "August";
pdfdocument.Save(dataDir + "replacedtextw.pdf");
