Merge Layer Down

合并图层下降

Merge Layer Down

合并图层下降

This command merges the active layer with the layer below to form a single layer. This frees RAM and simplifies the layer stack, hence you should merge layers once you have finished editing them.

这个命令将活动图层和下面的图层合并为一个图层。这样可以释放 RAM 并简化图层堆栈，因此一旦你完成编辑，你就应该合并图层。

You can select this command only if both the layers are visible. 只有当两个图层都可见时，才能选择此命令 You can also merge layer masks with this command. There are two outcomes depending on whether the layer or the layer mask is active: 你也可以用这个命令合并图层蒙版。根据图层或图层蒙版是否激活，有两个结果:

Layer Mask Active. The layer mask is merged with its layer — the masked areas in the layer become genuinely transparent rather than masked and the layer mask is deleted. 图层蒙版激活。图层蒙版与图层合并，图层中的蒙版区域由蒙版变为真正的透明区域，图层蒙版被删除
Layer Active. The layer mask is merged with the layer as described above. Next, the layer down is merged with its layer mask — again, as described above. Finally, the two layers are merged to form a single layer. 图层激活。图层蒙版与上面描述的图层合并。接下来，向下的图层与它的图层蒙版合并，如上所述。最后，将两个图层合并为一个图层
