Fill the current layer with the selected color or texture. Click "Load" button to open the Load Texture Dialog to select a texture. If there is a selected area then only the area will be filled.
Select auto to automatically select fill methods. If the whole layer is transparent, then "filling the whole area" method will be used otherwise the "filling non-transparent area" method will be used.
Select "The whole area" to fill the whole layer with the selected color or texture without paying attention to whether part of the layer is transparent.
