I am having trouble getting a text field to auto size on a form I'm creating. I am setting the textSize of the properties to 0 in the properties of the TextField but it seems to just use the font set for the document. Here is the code I am using to create the TextField.

```
$pdf->TextField('description', 195, 32, array('multiline'=>true, 'lineWidth'=>0, 'borderStyle'=>'none', 'textSize'=>0), array('v'=>$description));

```
