Why I can paint on locked layer.

[pangloy]

Hello.
Why I can paint on locked layer.
I want to lock and can't do anything on that layer
Thank you. 😀

Why?

Because that is how locking a layer works in the Affinity applications.

From the Help:

Quote

Locking is useful when you need to prevent a layer from being moved or transformed unintentionally.

In Affinity, locking does not prevent you from doing things like painting on a layer.

Oh! I see. Lock for move
If I want to lock for paint, How can I do?
Thank you. 😀

You can't.

You can, but you won't like it.

a) Group the layer you want to protect.

b) Menu Layer >> New Group

c) Drag the image group into the empty group and collapse this group.

Pure nonsense, but at least you won't destroy the layer you want to protect. I do hope, that one day / version a lock means protection against everything.

I hope Lock layer for edit should be in next update. 😆

That is kind of funny, I just assumed that locking a layer did just that, "Locked all edits". So, "Locking" a layer is a bit of misnomer. I agree with Joachim with the notion of locking being pure nonsense. I should not be able to move, draw, erase, add an effect or pixel filter to a locked layer. This does indeed need to be updated to reflect what the name implies. In our team environment, I shiver to think that one of our graphic artist could edit a locked layer that I've spent hours working on.🤯 What's the point of locking it anyway. Resizing or moving it are the least of my worries.😏

Whatever "locked" means, someone else in your team can always mess up your work. You can't prevent that, as all they have to do is unlock the layer. The lock is maybe a hint that they shouldn't do that, and it would make it harder to happen accidentally. But they can edit it.

The purpose of locking is to protect yourself from yourself. In almost all graphic applications I have used, locking prevents anything from happening on that layer, especially painting on it. It is a safety feature to prevent accidentally messing up something you don't want to change (usually your source photo). It would be nice if Affinity Photo conformed to the industry standard expectations for locking.

The comment I replied to was from someone who wanted to prevent others from modifying their work. Locking can't do that.
