We did a rethink on channels, selections and masks last summer.
|
|
|
|
Traditionally, a mask is seen as an extra channel for an image, analogous
|
|
to the alpha channel. We want to do away with that idea.
|
|
|
|
A layer can have a number of permanent selections associated with it.
|
|
Such a selection can handle a composite method (determining the composition method
|
|
for the selected pixels) or a filter (making it an adjustment layer).
|
|
|
|
Of course, a selection is just an 8-bit per pixel single channel layer that
|
|
belongs to a layer, so all filters can work automatically on a selection,
|
|
except that we don't have the ui for that yet.
