How to generate text into an image?

Question

PHP

You need to create a canvas 230px by 100px and add text there right in the center of the canvas with automatic line wrapping. In this case, words can be highlighted in bold.
All clambered, I can not find a solution on imagick.
I would do it manually, but I need to generate 5000 images. I thought either to do it on the fly using php and imagemagick, or maybe the program is what it is.

Answer 1

Only bold does not highlight individual words.
