2.3.2 Raising Layers
The order of layers in the Layers Palette controls how the layers are
perceived in the image. The Raise Layer entry, shown in Figure
2.5(c), shifts
the active layer up by one, if possible, in the layer stack. The
function Layer to Top puts the
active layer at the top of the stack.
Raise Layer and Layer to Top are also available from the
button bar. The upward-pointing arrow icon provides these
functions. Clicking on this button raises the active layer, and
Shift-clicking raises the layer to the top of the stack. Note that if
the lowest layer of the stack does not have an alpha channel, it cannot
be raised.
