Formatting Issues When Converting Text to JPEG

I am trying to utilize the information from your article "ASP.Net: Convert Text String to Image using C# and VB.Net" but ran into a formatting issue.  I am trying to create functionality that will allow a user to create a custom signature line (or two) and save it as a JPEG.  Using your code, I entered the following: ____________________________________     ____________

Guardian Signature                                          Date

However, when this gets save as a JPEG it is rendered:

___________________________________      _________

Guardian Signature                 Date

Is there any work around for this?

Thanks in advance.
