When I do Document / Fill, the color is applied to the whole layer.

How to protect alpha?

I do not think there is a handy button "protect alpha" (which often would be useful), but people use selection (cmd-click layer) or some masking function to save transparency. Please advice me if there is quick and easy way.

For some reason, protect alpha disappears when I want to use the edit/fill command.

Even if I check the option, edit/fill still fills the whole layer:

At this point, I'm not sure whether it is a bug or the way it actually works.

If it's the latter, I'll submit a feature request.

 

p.s. I tend to avoid cmd-click or ctrl-click layer as it adds more pixels to the actual layer's contents.

"Protect Alpha" is a Context menu bar option only available for pixel level operations (like for the Paint Brush & Pixel tools). It limits the effects of those tools to pixels that are not transparent. (There is no "Document/Fill" item I can find in the AP menus.)

 

The Edit > Fill... menu item is a layer level operation that affects the entire selected layer. This is (somehow?) different from the Layer > New Fill Layer menu item, because unlike that it pops up a "Fill" panel window with several options. Some are fairly obvious, like Custom color, Primary Color, & Secondary Color, but Inpainting & to a slightly lesser extent History are a mystery to me, & I can't find anything in the Help system that explains them.

 

Maybe someone else can explain what they do. Hosts ...?

I would go with what's behind curtain #3  :D .

 

The Flood Fill Tool (paint bucket icon)... with Tolerance set to 100% and Contiguous unchecked.

 

Example with a couple knockouts and Flood Fill (one click in both cases)...

Nice solution JimmyJack.

Thanks for posting it!

 

I wish the edit/fill would have the protect alpha, as it would be a faster method.

 

Best,

Andrew

@verysame

 

Will this work for what you want to do?

 

Select > Alpha Range > Select Opaque

 

Then use Edit > Fill


Due to the fact that Boris Johnson is now our Prime Minister, punctuation, spelling and grammar will never be worried about ever again.  We now have far bigger problems to be worried about.
