2.6.1.1 Moving Layers
Moving a layer is accomplished using the Move
tool. This tool is invoked by clicking on the Toolbox button
displaying the four-way arrow icon. Clicking on this tool changes the
mouse cursor to a four-way arrow when it is in the image window.
Clicking and dragging while the cursor is in the image window causes
the layer underneath the mouse cursor to move. The layer affected is
the one that is highest in the layer stack and has pixels more than
50% opaque under the mouse cursor (see
Section
5.7 for more on opacity and
transparency). This means that if the top layer is transparent at the
mouse cursor position, it is not moved. This also means that if the
active layer is transparent at the mouse cursor position it is not
moved. Rather, it is the first layer from the top that has more than
50% opaque pixels under the mouse cursor that is moved.
Alternatively, the active layer can be forced to move by
Shift-clicking and dragging. This moves the active layer regardless
of its visibility, degree of transparency, or position with respect to
the cursor.
