Someone on the registry wanted this compiled so here it is.
You will find it under Filters>Blur>Focus Blur
Looks like this -



Zip attached

Install in plug-ins folder in your USER directory.
No src is included, just the 32 bit plug-in.

Hello,

Is there a 64bit version availale for the same. I am using Win10, Gimp 2.8.2. ?

Rod,

I believe you do not have a 64bit environment, as I have read from another of your post. Can anybody else help?

Thanks

It has already been done. see: viewtopic.php?f=9&t=7954#p103101

You need an extra dll to go with it

libfftw3f-3.dll which you can get from: http://www.fftw.org/install/windows.html

The 64 bit zip contains several files but the one above is all that is needed.

Put the focusblur and libfftw3f-3.dll in your Gimp profile plug-ins folder. The filter shows up in the Filters -> Blur menu.

In Win10 (VM) looks like this with everything showing.



There are also one or two flters in the gmic plugin http://www.gmic.eu In the testing section: Tom Keil DoF / garagecoder depth blur (edit) and another in degradations - blur depth of field

I tried to install the 32 bit version, and get this error:

Oops, didn't see this. Ignore my previous post, haha.

Really all you needed to do was place the focus blur executable in its own folder inside the plug-ins folder and point Edit>Pref>Folders>Plug-ins to it. Do this with any dll error.
As the pixbuf dll is found here C:\Program Files\GIMP 2\32\bin

Thanks Graechan. Good to see you again. =)

Is there a specific interesting use of this special blur?
Just tried it (using the image itself as depth map), it runs very slowly and blurs almost everything.
Is there a mini-tut for its use?

Focus Blur plug-in is blurring effect, a kind of called DoF. This software makes a out of focus with luminosity and depth, like a sight or lenses. It can be used with depth map, depth fakes and shine effect. Also it can work as simple and applicable blur.

A mini-tut?
I've tried to apply B&W masks but no reasonable result.

I have used the plugin in the past, but it is from a earlier time when images were smaller. It is very slow on a larger image.

The gmic degradation Blur(depth-of-field) is worth a try if you need a dof effect.

The default with 2 zones works well or this, the alternative using a mask - a radial black-to-white gradient followed by painting in the foreground.

Thanks Rich, you confirm the detected slowness, and thus I will not use it (I could use it ONLY if a VERY INTERESTING effect could be easily obtained).

The term is " Does What It Says On The Tin"

...and "nobody uses it"...

There seems to be a problem with couple of missing dlls. Will post screenshots in the following post.

Appreciate the help.

Thanks

They are not missing. You simply need to place the focus blur plugin in its own folder INSIDE the plug-ins folder and direct GIMP to it with Edit>Preferences>Folders>Plug-ins>YourFolderName

Then restart GIMP.
