Photoshop activeDocument.gradients屬性

Question

我使用Photoshop CS4，當我使用Adobe腳本來檢查此屬性時，我得到未定義。我如何訪問Photoshop中文檔的加載漸變以通過腳本操作它們（例如，修改漸變停止，刪除漸變...）？

Answer 1

我知道這是一個古老的職位，而且不會出現上在Photoshop refrence guide.However梯度性質的任何信息......

與上一個空白640x640圖像的使用scriptlistner簡單前景到背景的梯度，我們得到這樣的：

executeAction(id148, desc24, DialogModes.NO); 

不幸的是，它不是隻喊你需要通過名稱梯度一樣容易，你可能會更好使用與scriptlistner所需的梯度記錄。
