WP Retina 2x

説明

This plugin does two things: it creates the image files required by the High-DPI devices and it displays them to your visitors accordingly. Your website will look beautiful and crisp on every device! The retina images will be generated for you automatically (though you can also do it manually) and served to the retina devices. The concept of retina images for full-size images is also a very unique feature which is only provided by this plugin (which is why it became unique). More information and tutorial available on the official website.

Retina Methods

It supports different methods to serve the images to your visitors. Why? Depending on the theme and plugins you are using (and also the way you use images in your website), not all the methods can work. Ideally, I would recommend using the Responsive Images method, then if it doesn’t work, the PictureFill method (which covers normally most cases). Retina.js should be the fallback method. There are more methods than this with their specific options.

Plug & Play

With a well-made theme and website, this plugin doesn’t require normally any specific set-up. All the defaults settings are fine. Works with multi-site and many kinds of installs.

Responsive Images

レスポンシブ画像。WP はレスポンシブ画像をサポートしています。このプラグインは WordPress が作成した src-set ディレクトリに retina 画像を追加することで、この機能を上手く利用できるようにします。WP 4.4 では処理されない画像の HTML (記事外のもの) も、このプラグインが適切に処理します (そのためには “Picturefill” メソッドを使用します)。このプラグインは、WordPress が生成した役に立たない ‘Medium Large’ 画像を無効にする便利な機能も提供します (基本的にこれはハックです)。

Optimized

The plugin is very fast and optimized. It doesn’t create anything in the database.

Pro Version

The Pro version adds support for Retina for full-size, support for lazy-loading for your responsive images and various options. And it supports my work 🙂

CSS & Background Images

The plugin cannot inject CSS to handles the images added through CSS, that’s both too dangerous and potentially very incorrect. However, in its Pro version and with PictureFill, you get an option to replace the inline CSS background image by their retina equivalent.

クイックスタート

  1. Set your option (for instance, you probably don’t need retina images for every sizes set-up in your WP).
  2. Retina 画像を生成する (初回のみ必要で、以降は自動的に画像が生成されるようになります)。
  3. プラグインが動作しているか確認してください!もし上手く動かない場合は、よくある質問やチュートリアルを読んだり、フォーラムをチェックしてみてください。

FAQ

ユーザーへ: よくある質問についてはこちらのページをご覧ください。 https://meowapps.com/wp-retina-2x/faq/

開発者へ: WP Retina 2x にはわずかな API があります。以下にフィルターとアクションを挙げます。

関数
  • wr2x_get_retina_from_url( $url ): return the URL of the retina image (empty string if not found)
  • wr2x_get_retina( $syspath ): return the system path of the retina image (null if not found)
アクション
  • wr2x_retina_file_added: called when a new retina file is created, 1st argument is $attachment_id (of the media) and second is the $retina_filepath
  • wr2x_retina_file_removed: called when a new retina file is removed, 1st argument is $attachment_id (of the media) and second is the $retina_filepath
フィルター
  • wr2x_img_url: you can check and potentially override the $wr2x_img_url (normal/original image from the src) that will be used in the srcset for 1x
  • wr2x_img_retina_url: $wr2x_img_retina_url (retina 画像) をチェックして上書きすることができます。2x に対する srcset として使用されます。
  • wr2x_img_src: $wr2x_img_src をチェックして上書きすることができます。この値は画像の src として使用されます (Pro バージョンのみ)。
  • wr2x_validate_src: 画像の src が渡されます。有効な場合にはその値を返します。null を返した場合は、処理がスキップされます。

評価

Makes life much simpler

Jordy is not only a programmer but a photographer. WP Retina takes away doubt about how to serve images in this high pixel density world. An absolute must plugin for photographers.

Perfect for me

Very well coded, works out of the box and is easy to understand. Also the translation works without issue. So for me it is software how they should be.
