  Поведінка параметра <code class="parameter">bestfit</code> змінилася в Imagick 3.0.0.
  Раніше він не діяв на зображення розмірів 400x400 та 200x150. Починаючи з
  Imagick 3.0.0, такі зображення отримають розмір 400x300, оскільки це &quot;найкраще
  підходить&quot; для заданих розмірів. Якщо параметр <code class="parameter">bestfit</code>
  використовується, необхідно вказати як висоту, так і ширину.
