ChromaPulse
One time purchase and 5 times trial.
“ChromaPulse” は塗りに画像が設定されたノードの
ドミナントカラー（支配色）やアクセントカラー（差し色）を抽出し、パレットを生成する
Figmaで動作する色調解析プラグインです。
マルチプロセス
同時に最大10個までの
画像解析を可能としています。
アルゴリズム
-
ドミナントカラー
画像を支配する色を満遍なく解析し、パレットの生成を行います。
color-thief が採用するメディアンカット量子化（MMCQ）アルゴリズムによる抽出方法です。
-
アクセントカラー
彩度や明度のターゲット値に基づいて色を選び、ドミナントカラーとはひと味違う鮮やかな結果を得ます。
node-vibrant によるアルゴリズムを採用した抽出方法です。
-
アベレージカラー
画像の平均色を得ます。
※パレット数の指定に関わらず、アベレージカラーの抽出で得られる結果は1色のみとなります。
スキャン粒度
画像解析時のスキャン粒度の指定です。
粒度を細かくすると解析用の画像を
強く縮小してから処理するため
高速になり、
粗くすると解像度を保ったまま
処理するため
やや低速になります。
粒度は結果の良し悪しを決めるものではなく、
パレットの色の近さ・バリエーションを
変化させるオプションとお考えください。
細かいほど似た色にまとまり、
粗いほどバリエーションに富んだ結果になります。
ドミナントカラー・アクセントカラーの
いずれにも同様に影響します。
