Hi
Hi Don,
Thanks for contacting support and sorry for the delayed response.
Aspose.Pdf for .NET supports the feature to extract text from a particular page region and you can use the same text to replace contents of another file. Please try using the following code snippet to fulfill this requirement.
C#
// open document
Document doc = new Document("c:/pdftest/HTMLConversion.pdf");
// create TextAbsorber object to extract text
TextAbsorber absorber = new TextAbsorber();
absorber.TextSearchOptions.LimitToPageBounds = true;
absorber.TextSearchOptions.Rectangle = new Aspose.Pdf.Rectangle(200, 200, 450, 350);
// accept the absorber for the first page
doc.Pages[1].Accept(absorber);
// get the extracted text
string extractedText = absorber.Text;
