| ===== Примеры запуска ==== | ===== Примеры запуска ==== | ||
| - | ===== Обзор параметров ===== | + | Вот список из нескольких примеров конвертирования, который показывает насколько полезна и легка в использовании утилита. Давайте для начала сконвертируем изображение из JPEG в формат PNG: |
| + | <code bash>$ convert rose.jpg rose.png</code> | ||
| + | Теперь, мы уменьшим размер изображения перед тем, как записать его в формате PNG: | ||
| + | <code bash>$ convert rose.jpg -resize 50% rose.png</code> | ||
| + | <колонки 100% 40% ><новаяколонка> | ||
