Saving ARGB 32 Bits BPM in Photoshop


Ok, I have an Image in 8 bits per channel mode on Photoshop. When I try to save it doesn't let me select the A8 R8 G8 B8 option.

Why I can't do it? There's a special mode that I have to choose to make this option available?

Here's a screenshot. Only the XRGB (leading zero) it's availabe and I need the leading Alpha option.

Sorry for any misspelling

You can't select ARGB because there's no alpha channel in your document. ARGB requires an actual, for real alpha channel.

I'm not sure why your application requires it, but a simple way to make that selection available is to add an empty alpha channel, or select a layer and save the selection (which creates an alpha channel).
