-> , from the image menu. The new layer is always given an alpha channel, and filled with a solid color, for which you have four choices. The Mode for the new layer is set to "Normal", the opacity is set to 100 (completely opaque), and "Keep Transparency" is set to "off". By default the new layer is given the same size as the image, but you can change this. You cannot alter the position of the layer within the image using this dialog: it can only be moved after it has been created. (See theHere you assign the layer a name. This does not have any functional significance: it is simply a convenience to help you remember the role you intended the layer to play when you created it. By default, the name "New Layer" is used. If a layer with this name (or whatever name you choose) already exists, after you hit the "OK" button, a number will be appended to the name in order to make it unique, i. e., "New Layer#1".
Here you set the dimensions of the new layer. When the dialog appears, the values are initialized to the dimensions of the image. You can change them, and if you want to use units other than pixels, you can get them using the Units menu to the right. You can't set the position of the layer within the image here, but you can always move it after it has been created.
Here you have four options for the solid color that will fill the layer: the foreground or background colors as shown in the Main Toolbox; white; or transparent.
