Offset
Offset moves the current layer or channel up, down, left, or right by the chosen number of pixels. When pixels overrun the dimensions of the layer, you can decide if they are wrapped or not. Offset can be used to place layers or floating selections to a specific position in the image. Offset is useful if you want to move layers a very exact amount, or if you'd like to move them without extending the layer border. The other important application of this command is to create seamless tiles for patterns. If the Wrap Around button is checked, after you offset the layer or selection, the parts of the image that moved outside the layer border will turn up on the other side of the image. If you don't want this, you can choose to fill the empty area with the background color or with transparency. Index
