The command shifts the
content of the active layer. Anything shifted
outside the layer boundary is cropped. This command displays
a dialog which allows you to specify how much to shift the layer and
how to fill the space that is left empty by shifting it.
7.49.1. Activating the Command
-
You can access this command from the image menubar through
→ → ,
-
or by using the keyboard shortcut
Shift+Ctrl+O.
7.49.2. Using the “Offset” Command
-
Offset
-
-
X; Y
-
With these two values, you specify how far the contents of
the layer should be shifted in the horizontal (X) and
vertical (Y) directions. You can enter the offsets in the
text boxes. Positive values move the layer to the right
and downward. The default unit is pixels, but you can
choose a different unit of measurement with the drop-down
menu. A unit of “%” is sometimes useful.
-
Offset by x/2, y/2
-
With this button, you can automatically set the
X and Y offsets
so that the contents are shifted by exactly half the width
and half the height of the image.
-
Edge Behavior
-
You can specify one of three ways to treat the areas left empty
when the contents of the layer are shifted:
-
Wrap around:
The empty space on one side of the layer is filled with the
part of the layer which is shifted out of the other side, so
none of the content is lost.
-
Fill with background color:
The empty space is filled with the background color, which
is shown in the Color Area of the Toolbox.
-
Make transparent:
The empty space is made transparent. If the layer does not
have an alpha channel, this choice is not available (grayed
out).
