Layer FX - Inside outline changes to white or transparent

Recommended Posts

When setting  the inside outline Opacity to 0%, it changes to white or transparent depending if Document > Transparent background is checked or not.

1.6.5.123 (or .135) works the same way, and it seems reasonable to me.

How else would you expect it to behave?

Here's a sample from 1.6.5.135:

Try it with an image

Max out the Radius and start reducing the opacity, would you not expect to start seeing the "masked" out part of the image again, when using an Inner Outline effect.

(Rather than plain white or transparent)

Good suggestion.

Certainly if I were overlaying the image with a rectangle, and reducing the opacity of the rectangle, I would expect to start seeing the image showing through. And possibly an inner outline should work like that, for consistency.

But there is a difference, because an overlaid rectangle is a separate layer, and in the case of the inside outline, that's a layer effect within the layer that is replacing image content in the layer.

Even if the outline's opacity is reduced, it should still replace image content because it is not a separate layer but an effect on the layer. It remains an outline, and if reducing its opacity were to reveal part of the image, you'd lose the outline.

So in my viewpoint, it's operating correctly.

Maybe

But why do inner glow and inner shadows work differently, in that they do show the underlying image when opacity is reduced

And in the real (physical) World if I was to put a frame around the inner boundaries of a picture then replace that frame with one that was more translucent I would expect to be able to start to see the parts of my picture which I could not see previously

I can only guess. Assuming that the behavior of the outline is not a bug, then the difference between an outline and a glow or shadow is that the glow/shadow are manipulating the content of the image pixels, and thus varying the opacity will have a greater or lesser effect on those pixels.

But the outline, as I mentioned above, is replacing the pixels completely, regardless of its opacity.

Or, maybe there's a bug, though I don't think there is :)

Yes I know. But, IMHO it's illogical !! I just wanted to quote that...

Photoshop does the same thing, however they have an option called 'Overprint' which apparently negates this—so you can have it either way, depending on your preference.

This was logged as an improvement a while ago so I'll go and give it a kick and see what's happening.
