I have an image with multiple layers, each layer has stars, satellite trails on a black(ish) background.
I want to export each layer to its own image, but with the black masked out. That is, each layer with an inverted mask. I’m not getting how the “apply mask” option works, if that’s appropriate.
Or, do I have to run through all 50+ layers, apply a mask then invert the mask?
The “Apply mask” option makes sure that any layer mask that is associated with an individual layer is applied on export. So, unless your layers already have a layer mask associated with them, the option isn’t going to do anything.
If I’m understanding you correctly, then what you want to do isn’t going to be easy. You’d have to add a mask on every layer.
But, maybe if you explain a bit more what you’re after I can come up with a solution. Are you wanting a little masked logo on every layer? Is this something Retrobatch could do for you?
if I apply a mask to one layer, invert the mask, can I copy that layer mask and paste onto other layers?
The desired outcome is to end up with a bunch of files that can be processed separately (e.g. might add these as layers to a different animated gif if the images align) but really want just separate files processed in the same way. I did think that this is a job for Retrobatch, but I don’t know if mask to alpha is what I want.
It might still be possible to do what you’re after if you want to try and chase that idea down. If not, no worries (I’d have to see what your image looks like, and then what you want it to look like in the end).
I don’t know if it is out of the scope of what Acorn is aiming for. I did a bit of research and it turns out that inverting layers (including masks) is a bit specialised, though it is quite powerful with masks.
Am I correct in that while a mask can apply to a layer in Acorn, it’s not actually its own editible layer unless you eject it? and if you eject it, can that ejected layer be reapplied back to the layer?
