Layer Mask

[f242]

Is there any plan to implement the "Layer Mask" feature? The only thing stopping me from switching to lightweight editors like PaintFE, Paint.NET, and similar apps is that — for some reason — this particular functionality is only available in heavy, full-featured editors like Photoshop, Krita, and GIMP, whose capabilities are simply overkill for my needs.

Hey! So currently it hasn't been fully tackled since the GPU stack is quite complex for this, but for now we have a "Merge Down as Mask" feature which you can access by right clicking a layer, this uses the layer as a mask and applies the alpha values to the layer below. If this doesnt suite the needs though please list out how you think it should work/what you would want so I can look at implementing it even if a simpler version :)

In version 1.2.6 I've added Layer Masking, at least a basic implementation of it, might still be issues let me know if you find any and I can improve it, also if you want to see it extended/refined further. Supports making layer masks, editing them, disabling them, applying them, inverting them.

Hello! I tried using a layer mask in v1.2.8 but couldn’t figure out how it works in this editor. I see the option in the menu, I choose “add mask,” but nothing changes and there’s no indication of it anywhere. Usually, I enable a mask on a layer to conveniently erase parts of an image when layering elements over each other. When working with a mask, all that’s left is switching between black and white colors.

Yeah all good! I'll update the website/docs with tutorials/guides for it soon!

So what you do is right click on a layer to add a layer mask, I recommend adding a reveal all mask. Then you right click on it again to edit the mask, you can also disable/enable or invert it here.

When editing it reads opaque pixels as transparent so you can paint with the brush or tools in black/white etc where you want to mask, using the eraser tool to remove, you should see it reflected live and you can exit mask mode and go back into edit pixels mode on right click.

I can adjust the behaviour and how it works with feedback or more suggestions! :)

Just let me know if this works and is understandable first.
