剪贴蒙版和透明度继承

The exception is when using pass-through mode, meaning that alpha inheritance won’t work right when turning on pass-through on the layer.

当我们对图层打开透明度继承时，该图层与在它之下的图层保持相同的透明度。

Here we have an image with line art and a layer for each flat of colors. We want to add complicated multi-layered shading to this, while keeping the neatness of the existing color flats. To get a clipping mask working, you first need to put layers into a group. You can do this by making a group layer and drag-and-dropping the layers into it, or by selecting the layers you want grouped and pressing the Ctrl + G shortcut. Here we do that with the iris and the eye-white layers.

We add a layer for the highlight above the other two layers, and add some white scribbles.

Now there’s an easier way to set up alpha inheritance. If you select a layer or set of layers and press the Ctrl + Shift + G shortcut, you create a quick clipping group. That is, you group the layers, and a ‘mask layer’ set with alpha inheritance is added on top.

The fact that alpha inheritance can use the composited transparency from a combination of layers means that you can have a layer with the erase-blending mode in between, and have that affect the area that the layer above is clipped to. Above, the lower image is exactly the same as the upper one, except with the erase-layer hidden. Filters can also affect the alpha inheritance:
