Is there any way to edit prexisting alpha layers?

[Draven]

Just as the title says is there anyway to edit a pre-existing alpha layer?

As in you open a .png that has an alpha layer/channel, where can you see that and edit it?

I'm new to the software (recently bought it during the winter sale) and briefly looking over it I did not notice any way to edit a pre existing alpha layer/channel.

I'm coming from gimp so things may be a little different so yeah forgive me if I missed the obvious.

A layer is not a channel. An alpha channel just means pixels can have a transparency from 0-255. It's still the same layer as the color values. You can "see" the alpha channel just by seeing the transparency in the image.

Instead of trying to prove me wrong about terminology you could actually be helpful which you weren't at all.


Edit to explain better for people who wish to condescend me instead of prove helpful:
In photoshop the alpha is split into a channel, where as it's split into a layer via's gimp's add layer mask transfer layers alpha channel. So yeah I do know what I'm talking about.

And as far as I can tell there is no way to do this in Aseprite?

I don't know why you chose to interpret my reply as condescension and "proving you wrong" intead of what it was, trying to sincerely explain something where I could only assume you had some misconceptions. How was I supposed to know how much you knew? I wasn't being rude, but you sure were with that reply.

So you're talking about a layer mask, no there is no such feature.

Hi Sidikian, at this moment you cannot edit the alpha channel separately (e.g. like on Photoshop that can show you the channel as an grayscale image). There is a "lock alpha" ink, to paint only color and do not modify alpha, but it's just the opposite of what you are looking for. I'm taking note for a future release.

Thank you for the reply.

Ah, but "lock alpha" solves my problem, so thank you.

Lock alpha does not work for gradients right? Im trying to change the color only of a layer and currently faling at that. I I could just lock alpha of layers, regardless of copying it anything using any tools that would solve my issue.

@Thultex at the moment gradients don't have the "lock alpha" ink (or other kind of inks). We need to simplify this alpha editing/locking mechanism to make it more generic to all tools/transformations.
