Fill PDF Form

This Python script uses the Aspose.PDF library to manipulate a PDF file with form fields. Here’s a step-by-step breakdown:

• Import Aspose.PDF module: The code imports the Aspose.PDF library using the alias pdf.
• Load the license: It loads the licensing information required for Aspose.PDF operations.
• Load the PDF with form fields: The script loads a PDF file named “TextBox_out.pdf” that contains form fields.
• Access the target form field: It retrieves the first form field from the loaded PDF file.
• Set a new value for the form field: Updates the value of the retrieved form field with a new text.
• Adjust the appearance of the form field: Modifies the appearance properties of the form field, changing its text color to red and adjusting the vertical alignment to the bottom.
• Save the modified PDF with filled form fields: The script saves the modified PDF document with the updated form field values as “TextBoxUpdated.pdf”.
• Print a success message: Displays a message confirming that the form fields have been successfully filled in the PDF file.

Check out this code snippet to see it in action:

    import aspose.pdf as pdf

    # Load the license 
    license = pdf.License() 
    license.set_license("Aspose.Total.lic") 
    # Load the PDF 
    pdfWithFormFields = pdf.Document("TextBox_out.pdf") 
    # Get target field 
    formFieldTextBox = pdfWithFormFields.form.fields[0] 
    # Set new value 
    formFieldTextBox.value = "Here is the new value for the form field" 
    # Set the field appearance 
    formFieldTextBox.color = pdf.Color.red 
    formFieldTextBox.vertical_alignment=pdf.VerticalAlignment.BOTTOM 
    # Save the filled PDF 
    pdfWithFormFields.save("TextBoxUpdated.pdf")

In summary, this code uses Aspose.PDF in Python, loading the license and opening a PDF file named “TextBox_out.pdf” with form fields. It selects the first form field, updating its value and adjusting its appearance (color to red, vertical alignment to bottom). After filling in the form fields, it saves the modified PDF as “TextBoxUpdated.pdf” and prints a success message.
