Photoshop activeDocument.gradients 属性

Question

我正在使用 Photoshop cs4，当我使用 adobe 脚本检查此属性时，我得到未定义。如何在 Photoshop 中访问已加载的文档渐变以通过脚本对其进行操作（例如修改渐变停止、删除渐变...）？

Answer 1

我知道这是一篇旧帖子，在 Photoshop 参考指南中似乎没有关于渐变属性的任何信息。但是...

使用scriptlistner 在空白的 640x640 图像上使用简单的前景到背景渐变，我们可以得到：

不幸的是，这并不像只通过名称调用您需要的渐变那么简单，您最好使用 scriptlistner 使用所需的渐变进行录制。
