GIMP Bloom Perl-Fu script by wwwwolf GIMP Bloom Perl-Fu script by wwwwolf
NOTE: There's a Python-Fu version of this script now available. If you already have the Perl version, though, this doesn't have too many other improvements though.


This is a GIMP 2.4 Perl-Fu script that does a light bloom effect.
More bloom... m-m-m-more bloom... Damn, I have to go beat Twilight Princess again, sorry, bye, I'll be right back...

It's based on a tutorial by Matthew Welch, but I'll probably add a few more variants later on - basically, I just did this to get my fingers stretched since I haven't programmed GIMP scripts for a very long time. Now that there's actual documentation for GIMP scripting, I might actually convert my old scripts over to the 2.x era. =)

To install, stick in ~/.gimp-2.4/plug-ins/ - you may need to make it executable (chmod +x That's for Linux - while this should run on all other GIMP versions that have Perl-Fu, I don't have specific instructions for Windows or OS X right now, sorry. I imagine it won't be much more difficult.

The script will appear under Filters - Light and Shadow in the image menus. Unless you select "Flatten final image", the script will only create a new layer that has the new highlights - you can, and probably should, tweak the layer. By default, the script uses "Soft Light" mode on this layer, but for certain images, "Hard Light" looks nicer (also used in the preview images above), and you can adjust the layer opacity (and add other corrections) after the fact.

Thanks for the :+fav:! I haven't touched Twilight Princess for a while. One can get a bloom effect overdose if Z:TP is played while also playing The Elder Scrolls IV: Oblivion. Besides, I still haven't played through Majora's Mask, which can be played safely without massive exposure to the awesomeness of the bloom effect. =)

I dont get what perl-fu script is....I just downloaded the file and put it into the scrip-fu foleder...but it didnt pop up under light and shadow...

Perl-Fu scripts go under "plug-ins", not "scripts".

Perl-Fu is also an optional component of GIMP. In Debian (and I guess Ubuntu) it requires package "libgimp-perl", I don't know about other OSes. If you can find plug-ins such as "<Toolbox>/Xtns/Render/Logos/Glowing Steel", "<Image>/Filters/Distorts/Scratches..." or "<Image>/Filters/Map/Xach Shadows...", then in all likelihood you have Perl-Fu support.
Yes python is more cross-platform .
Install on windows take just few minutes,here all is needed to install python support for gimp on win in a single pack.


if gimp is already installed is needed a reinstall

all means really all including last python
i don't think is a problem install perl in windows as was not a problem install Python

the problem is in the gimp perl module, in windows gimp support python only from 2.4

and a fear may a problem for MAC too

Hmm, well, that sounds curious. I may take a look at converting these to Python if that's more cross-platform capable. One thing is sure - I hated writing scripts in Script-Fu/Scheme back in the day (no proper feedback whatsoever) so I don't think I'll write it in it. :no:
for windows i believe will be close to impossible install it...

Is not question to install Perl, is the gimp-perl module that is not available for windows, and i fear for MAC

Hmm, fascinating. I was aware that Windows compatibility could be problem - but I'd guess there should be some way to make it work on Mac, after all, GIMP is just an X11 program and Mac already has Perl by default...
