title: What is the difference between ImageMagick and libGD?
body: <p>I don't know anything about either library but I have to choose one of them.
  Which one whould you recommend?</p>
  
  <p>I'm using Perl. I need to generate images for weather site. The image is generated for a location and should contain temperature and a weather condition image inside. I guess this is a piece of cake for both libs. But I want to know which one is more powerful. I've read that libGD is not able to rotate text. Maybe there are some other drawbacks? Which one generates images faster? Whose API is easier to use? </p>
