This is quite hard to do, we use the PHP extension Image to do the text to image conversion. Unfortunately the extension is quite limited with what you can do with the text. The only way to get this is done is to fix the ImageGD library AND the Image extension, something which is outside of the scope of eZ publish.
The function that we use in eZ publish is.

Thanks.
What I need is a way to determin the pictures width and if it is over a given width, return it as two images (i don't know if I need a <br/> inbetween the pictures.)
My problem is that if editors enter a too large heading, it destroys my design (table based)... Is this possible from tpl programming? Frode

I think, you can limit your header text to "n" characters, before sending it to "texttoimage".
There is an operator in ez for that (shorten, see http://ez.no/developer/ez_publish_3/documentation/development/libraries/ez_template/operators/string_handling#shorten)
See, your template would be something like
{$header|shorten(20)|texttoimage('arial')}
Maybe you could even "wrap" your header (will insert \n ) and then send it to imagetotext. I don't know, if imagetotext is able to create multi-line-images.
(see http://ez.no/developer/ez_publish_3/documentation/development/libraries/ez_template/operators/string_handling#wrap )

You can use wrap operator on texttoimage : {$node.name|wrap(20)|texttoimage( 'arial',,20,,,'#064D95',,,,5 )} or use a special character (like '$') to introduce a word wrap at a specific place in the string :
{if $node.name.content|contains('$')}
{def $wrappedTitleArr = $node.name.content|explode( '$' )}
<h2>
{for 0 to $wrappedTitleArr|count|dec as $counter}
{$wrappedTitleArr[$counter]|texttoimage( 'arial',,20,,,'#064D95',,,,5 )}
{delimiter}<br />{/delimiter}
{/for}
</h2>
{undef $wrappedTitleArr}
{/if}
