Expand contents of text field

Hi Team,

Can you please let me know how to manage the text flow for a Text field. I need a text field whose contents can be of any length . I want the Textfield to expand based on the content. The below TextField has a fixed size and If I enter more data the font size is getting reduced in the generated PDF. Please help me on this.

Document pdfDocument = new Document(@“C:\Users\wb541348\Desktop\IMP\POC\InteractivePdf\Output.pdf”);

        // Create a field
        TextBoxField textBoxField = new TextBoxField(pdfDocument.Pages[1], new Aspose.Pdf.Rectangle(100, 200, 300, 300));
        textBoxField.PartialName = "textbox1";
        textBoxField.Value = "Text Box";

        // TextBoxField.Border = new Border(
        Border border = new Border(textBoxField);
        border.Width = 5;
        border.Dash = new Dash(1, 1);
        textBoxField.Border = border;
        textBoxField.Multiline = true;
   


        // Add field to the document
        pdfDocument.Form.Add(textBoxField, 1);


        // Save modified PDF
        pdfDocument.Save(@"C:\Users\wb541348\Desktop\IMP\POC\InteractivePdf\Result.pdf");

Please note that Aspose.PDF mimics the behavior of Adobe Reader and based upon PDF specifications offered by it. We believe that this feature is not support in Adobe Reader neither in Aspose.PDF. Would you kindly share an expected PDF output which you want to create using Aspose.PDF. We will further check it and share our feedback with you.
