合并图层
在往期我们讲解我们讲解了图层的分类，主要为矢量图层，位图图层，智能对象图层，包括路径，锚点等等，今天让我们来学习如何合并图层。
在设计的时候，很多图形分布在多个图层上，而对这些已确定的图形不会再修改了，就可以将它们合并在一起便于图像管理。相应的合并后的图层不能进行单一细致的修改，因此合并图层需要慎重小心。
In the past, we explained the classification of layers, mainly vector layers, bitmap layers, intelligent object layers, including paths, anchors, etc. Today, let’s learn how to merge layers.
During design, many drawings are distributed on multiple layers, and these determined drawings can be merged together for image management without modification. The corresponding merged layers cannot be modified in a single and detailed way, so the merged layers need to be careful.
二、合并图层展示
合并图层快捷键：ctrl+E；接下来我们来看看不同类型的图层合并后的图层类型有何变化。
首先分别新建一个智能对象图层，一个位图图层，一个矢量图层。要注意图层合并的方式都是向上合并，智能对象图层和位图合并后的图层是位图图层。
同理，将矢量图层和位图图层合并后的图层为位图图层。
由此可知，除了矢量图以外，任何类型的图层合并后都会变成位图。另一种情况为，矢量图层与矢量图层合并后为矢量图层。注意：矢量图层只能有一种颜色，合并图层为向上合并，因此哪矢量一图层在最上方，合并后的图层颜色就和最上方的矢量图层一致。
合并后的矢量图层可以使用路径选择工具或者直接选择工具进行移动。

2、 Merge layer display
Shortcut key for merging layers: ctrl+E; Next, let’s look at the changes of layer types after merging different types of layers.
First, create an intelligent object layer, a bitmap layer, and a vector layer respectively. Note that the method of layer merging is upward merging. The merged layer of smart object layer and bitmap is a bitmap layer.
Similarly, the merged layer of vector layer and bitmap layer is a bitmap layer.
It can be seen from this that, except for the vector map, any type of layer will become a bitmap after merging. Another case is that the vector layer and the vector layer are merged into a vector layer. Note: Vector layers can only have one color. Merged layers are merged upward, so which vector layer is at the top, the color of the merged layer will be consistent with that of the vector layer at the top.
The merged vector layer can be moved using the path selection tool or the direct selection tool.
