Similarly named effects — how are they different?

[es]

What's the difference between these effects?
"Effect → Plug-In Filter → Gauss 7×7" and
"Effect → Blur → Gaussian Blur..."
I see that the resulting effect is similar (blur, but plugin seems a bit worse), but the parameter type for the second is different (a single number), and I can't seem to be able to customize the parameter for the Plug-In filter (there are 4 predefined pairs)

Are these embedded plugins? Though the app's "Contents/PlugIns/" folder only has the following
"FinderSyncHelper.appex"
"GCEditWith.appex"
"GCShareOpen.appex"
"GCTWAIN.bundle"
"ICAScannerBundle.bundle"
"Xe847.appex"

"Effect → Plug-In Filter → Gauss 7×7"
is a simple 7x7 matrix filter

"Effect → Blur → Gaussian Blur..."
is a dynamic filter provided by Apple core image

Yes, the other items are embedded plugins: Edit with and Xe847 for Photos, TWAIN and scanner for support of scanning, FinderSync for the extension of the Finder with i.e. GraphicConverter batch features.

Oh, ok, thanks for clarification. But then what do I do if I need to apply "10px gaussian blur" (am just trying to get an image that was done with this filter in some other app from this blog?

Sorry, I didn't ask it clearly, I was just trying to understand what "Plug-In" this Gauss filter was coming from, and the names and your explanation suggest that it's actually not from these files, but maybe part of the app itself or something (so just a bit confusing that it's called "Plug-In" then, but no big deal)

Just look into the app package for Contents/Resources/Matrices/

Thanks, and I can copy them to Application Support/GraphicConverter/Matrices/ and they'll get picked up by the menu

That leaves only one 10px-Gaussian question remaining

No, please do not change the app itself. That voids the Apple codesigning signature.

Just store custom Matrices at: ~/your_name/Library/Application Support/GraphicConverter/Matrices/

[es]

But that's almost exactly what I wrote :) "Application Support/GraphicConverter", just skipped the ~/Library part, sorry about the confusion
