Change layer to background

[default3opfpffzvbr6]

The guide says:

Follow these steps to convert a regular layer into the background layer:

Select the regular layer in the Layers panel.

Navigate to Layer > New > Background From Layer.

Any transparent pixels in the layer are converted to the background color and the layer drops to the bottom of the layer stack.

However, there is no background from layer. See Attachment.

I(s a layer in the layer panel selected?

Most likely you already have a Background Layer and if that's the case then you won't see the Background From Layer

menu item.

There is only one layer - Layer 1.

Can you post a screenshot of your Layers panel?

What colour mode is the document (Indexed or RGB)? It sounds like the reply from @Jeff Arola is applicable.
