??PS是一款柵格圖像編輯軟件，具有許多強大的功能，本文演示如何通過腳本實現(xiàn)秋色效果相關(guān)功能，展示從互聯(lián)網(wǎng)收集而來的一個小插件，供大家學(xué)習(xí)交流，請勿用于商業(yè)用途。

1.插件界面

??本文界面是一系列功能的一部分，將逐步展示，但是功能界面是共同的，如下圖所示：

2.關(guān)鍵代碼-秋色效果

??大家可通過源代碼閱讀，來掌握相關(guān)技巧，源代碼如下：

cTID = function(s) { return app.charIDToTypeID(s); };
sTID = function(s) { return app.stringIDToTypeID(s); };

//
