Pixel selections from layers

You can create pixel selections based on layers (or layer groups) or layer luminance.

If the layer or layer group contains areas which have an opacity lower than 100%, these are partially selected. This partial selection is based on the percentage of their opacity (i.e. areas of 20% opacity will be selected by 20%). Transparent areas will not be included in the selection.
