「marume」は、iPhone内の写真の「角を丸める」ことに特化した画像加工アプリです。複雑な編集ツールを省き、直感的なスライダー操作だけで、素早く思い通りの角丸画像を作成して保存できます。 【主な機能】 ・角丸サイズの無段階調整 スライダーを左右に動かすだけで、角の丸み(Radius)をリアルタイムに確認しながら変更できます。 ・アスペクト比(縦横比)の変更 1:1(正方形)、4:3、3:4など、用途に合わせて写真の比率を変更しながら切り抜くことが可能です。 ・丸める角の個別指定機能 4つの角(左上、右上、左下、右下)の中から、丸めたい角と丸めたくない角を個別にON/OFFで指定できます。 ・ダークモード完全対応 端末のシステム設定に連動し、暗い場所でも目に優しいダークモードUIで操作が可能です。 ・カメラロールへの高画質保存 加工した画像は画質を落とさず、そのままお使いのiPhoneのカメラロール(写真アプリ)へ保存されます。 【こんな用途におすすめ】 ・SNS(X、Instagram、LINEなど)のプロフィールアイコン画像の作成 ・ブログ記事やプレゼン資料に挿入する、柔らかい印象の画像素材の作成 ・ホーム画面のウィジェット用写真の加工
