Layer Boundary Size

General

The Layer Boundary Size lets you set the the boundary of the layer. Remember you can have a smaller or larger layer than the image boundary size. When you enlarge the boundary size, then you will add some space to paint on to your layer. Naturally it will be vice versa when you make the boundary size smaller.

The "Size" area will control how big or small your new layer boundary will be just as when you created a New Layer. The "Offset" area will control how your layer is clipped or expanded.

Making the Layer Smaller

The "Offset" fields will control where your upper left corner of the old layer will be in the "new" layer. The best way to control the new location and how and where the layer will be clipped is to drag the "layer preview" in the "Offset" area to the right position. Make the final adjustment with the spin buttons (or type it in by hand) if needs to be pixel-exact. The thin outline is the new layer size and you have to drag the old layer to the right position so it will be clipped according to your demands.

Making the Layer Larger

The "Offset" fields will control where your upper left corner of the old layer will be in the "new" layer. The best way to control the new location and how and where the layer will be clipped is to drag the "layer preview" in the Offset area to the right position. Make the final adjustment with the with the spin buttons (or type it in by hand). The outline/canvas is the new layer size and you have to drag the old layer to the right position within it.

The Chain Button

If you uncheck the chain in the "Size" area, you will be able to have different ratios when you make the "new" layer . It's therefore possible e.g. to have a layer which is smaller in X direction and larger in Y direction than before you altered the layer boundary size.
