Wrapping text using imagettftext

[jtrechter]

I have this long blob of text that I'm passing in to display as png, but of course the text doesn't wrap and so it's cut off. Is there a way to fix it?

I tried imagettfbbox and imagecreatefromstring, but I can't seem to specify the font file to use or choose the text color. Any ideas?
Thanks.

There are a few ideas in the user comments for imagestring(), here, such as creating the text as an image first then resizing it and adding it to your original image, or wrapping the text to fit the image.
