## カスタム `PNGStreamingResponse` { #a-custom-pngstreamingresponse }

上記の例ではバイト列をストリームしましたが、レスポンスに `Content-Type` ヘッダがないため、クライアントは受け取るデータの種類を認識できませんでした。

`StreamingResponse` を継承したカスタムクラスを作成し、ストリームするデータに応じて `Content-Type` ヘッダを設定できます。

例えば、`media_type` 属性で `Content-Type` を `image/png` に設定する `PNGStreamingResponse` を作成できます:
