I use Aspose.pdf.dll 11.0.0 (evalution) and this code.

Please tell me why adds a space and moves the text(see screen in attachment). Thank you!

private void button1_Click(object sender, EventArgs e)


// The path to the documents directory.

string dataDir = “c:\”;

//open document

Document pdfDocument = new Document(dataDir + “1.pdf”);

//create TextAbsorber object to find all instances of the input search phrase

TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber(“м3”);

//accept the absorber for all the pages


//get the extracted text fragments

TextFragmentCollection textFragmentCollection = textFragmentAbsorber.TextFragments;

//loop through the fragments

foreach (TextFragment textFragment in textFragmentCollection)


//update text and other properties

textFragment.Text = “м2”;


// Save resulting PDF document.

pdfDocument.Save(dataDir + “ReplaceTextAll_out.pdf”);

MessageBox.Show(“All GOOD!”, “END”);
