我在Flex项目中有一张照片:
<s:Image source="@Embed('images/photo.png')" />
但现在我想知道我是否可以将此图像设为下图,在Flex(4 / 4.5 / 4.6) (在MXML和/或 ActionScript 3中) ):
这可能吗?

这是您应该能够移植到Flex的feathering mask tutorial in flash。

是的,首先你需要使用AI或PS为圆角和内阴影创建一个遮罩层
现在为spark图像创建一个外观类,并在imageDisplay(BitmapImage)上方添加蒙版代码。

将此皮肤类应用于火花图像
<s:Image source="@Embed('assets/maskImg.png')" skinClass="MaskedImageSkin" width="200" height="200"/>
上面的代码只是屏蔽图像的一个例子,使用圆角矩形创建自己的蒙版。这将解决您的问题。
快乐的皮肤......
