+ * Minifies images.
+ *
+ * When the task is run without any specified minifier it will compress the
+ * images based on the extension.
+ *
+ * ```php
+ * $this->taskImageMinify('assets/images/*')
+ *     ->to('dist/images/')
+ *     ->run();
+ * ```
+ *
+ * This will use the following minifiers based in the extension:
+ *
+ * - PNG: optipng
+ * - GIF: gifsicle
+ * - JPG, JPEG: jpegtran
+ * - SVG: svgo
+ *
+ * When the required minifier is not installed on the system the task will try
+ * to download it from the [imagemin](https://github.com/imagemin) repository
+ * into a local directory.
+ * This directory is `vendor/bin/` by default and may be changed:
+ *
+ * ```php
+ * $this->taskImageMinify('assets/images/*')
+ *     ->setExecutableDir('/tmp/imagemin/bin/)
+ *     ->to('dist/images/')
+ *     ->run();
+ * ```
+ *
+ * When the minifier is specified the task will use that for all the input
+ * files. In that case it is useful to filter the files with the extension:
+ *
+ * ```php
+ * $this->taskImageMinify('assets/images/*.png')
+ *     ->to('dist/images/')
+ *     ->minifier('pngcrush');
+ *     ->run();
+ * ```
+ *
+ * The task supports the following minifiers:
+ *
+ * - optipng
+ * - pngquant
+ * - advpng
+ * - pngout
+ * - zopflipng
+ * - pngcrush
+ * - gifsicle
+ * - jpegoptim
+ * - jpeg-recompress
+ * - jpegtran
+ * - svgo (only minification, no downloading)
+ *
+ * You can also specifiy extra options for the minifiers:
+ *
+ * ```php
+ * $this->taskImageMinify('assets/images/*.jpg')
+ *     ->to('dist/images/')
+ *     ->minifier('jpegtran', ['-progressive' => null, '-copy' => 'none'])
+ *     ->run();
+ * ```
+ *
+ * This will execute as:
+ * `jpegtran -copy none -progressive -optimize -outfile "dist/images/test.jpg" "/var/www/test/assets/images/test.jpg"`
