Although the filter is intended to work that way, I consider it to be a bug.

As you know, GIMP 2.9 is still under heavy development, an done of the pending things is to find-put a way
to have the "classic" plug-ins installed back again on a running GIMP - that way, any regressions such as this could be work-arounded by installing the previous script.

In this particular case, I am in favor of restoring the extra-layer creation behavior, or at least have a checkbox to imply it. The uses I myself make of "drop shadow" always require a separate layer.

(For developers: I know that breaks the "a single gegl-op" paradigm for such a plug-in - since it would have to fiddle with the image layer stack - that means that some plug-ins can't simply become an op with automated GUI, but have to be actually coded and call GEGL and gimplib/pdb to manipulate the image)

For now, if you can find the "drop-shadow.scm" file from any gimp2.8 (or less) install and put it in yours scripts dir, it will work.

Hello

OnIRC-Channel they told me, it ist better to ask the developer directly or write in the bug-report. So, I hope this is the right place now for my question.

I took a first look of the new development version 2.9. on my win7 system. Great work!
My question: The new Filter “Drop Shadow” creates no extra layer. Is this a bug or a new feature?

It would be very importend for our work to get the shadow on an extra layer, because we need it for extra manipulations. It will be nice, if we have the choice to merge down the layers or not.

Thanks for your time to get it fixed. do-se (this is my nick in the gimp-world)

Joao,

Does this GEGL op do anything for you at all? Because it does absolutely nothing for me (duly noted in http://wiki.gimp.org/wiki/Hacking:Porting_filters_to_GEGL/UI_review), seperate layer or no separate layer.

Yes, I've just tested it and it is definitely working here. Apart from not allowing a separate layer,
the live-preview is a major enhancement. (but the default values could not be worse)

Maybe you are stuck to an old binary version of the operator from an old build?

Well, there is nothing impossible, but I do build GEGL and GIMP from clean Git checkouts and run 'make uninstall' before installing new stuff. I'll doublecheck when I'm back to my home desktop.

Is the "keep transparency" toggle enabled?

I've seen it do nothing, but I've also seen it work. It might have something to do with the scale or transparency of the active layer, but I haven't figured out the rules for when it works vs. when it doesn't.

In truth, I haven't tried very hard since the GEGL drop shadow doesn't work well enough to be usable, so I use the old non-GEGL plug-in. I agree with everyone else that the shadow needs to be on its own layer -- especially on text layers, where GEGL drop shadow currently does nothing except discard the layer's text information.

There is no such toggle in the GEGL op.

There is no such toggle in the GEGL op.

I was referring to the "keep transparency" toggle in the layers dialog. Which is still alive and kicking, even when used in conjunction with gegl ops.

Having it enabled would explain perfectly what you're seeing.
