理解和使用Photoshop的智能对象

作者：Johnson Koh　

In my opinion, Smart Object is one of the most useful feature in Photoshop. It allow us to save a lot of time in designing website and graphic user interfaces, where there are plenty of repetitive elements. If you have a good understanding on how a Smart Object behaves, it can also serve as a template for Photoshop effects.

在我看来,智能对象是Photoshop新增功能里最有用的项目之一.它可以让我们在网页设计和图像处理中节省很多的时间,比如需要有大量重复的效果时.如果你对智能对象的工作原理有一个很好的认识,它甚至可以作为模板批量应用一些图片特效.

What is a Smart Object?

Smart Objects are layers that contain image data from raster or vector images, such as Photoshop or Illustrator files. Smart Objects preserve an image’s source content with all its original characteristics, enabling you to perform nondestructive editing to the layer (quoted from Adobe ).

什么是智能对象?智能对象是包含栅格或矢量图像（如 Photoshop 或 Illustrator 文件）中的图像数据的图层。智能对象将保留图像的源内容及其所有原始特性，从而让您能够对图层执行非破坏性编辑。(摘自adobe的自述文档)

The image below demonstrates a nondestructive transformation done to a raster graphic. In normal conditions, a raster or bitmap image will turn blur after resizing for few times with the transformation tool (seen on left). By converting the raster image to a Smart Object, any transformations that come after will remain sharp like the original. All the pixels information are preserved upon the conversion (seen on right).
