Please note that... i forgot the URL of my own source ( when i set it up I tried a lot of sides..now i can't remember which i chosen ) and so as now i cannot put there but only post here

The filter is for downscale ,it uses the method discussed here viewtopic.php?f=4&t=5303&start=20
and can NOT be used to scale up, the final width and height MUST be minor (or equal )the original.



marked in red the essential controls:
the pre-blur is computed automatically so all what is needed is chose the new image size :
there are 3 options:

1) Set new Width and Height, use this to scale differently W and H
2) Preserve image ratio, set new W
3) preserve image ratio set new H

All the others controls are for 1 optional step for post sharpening
For this i was tempted to simplify, removing most of controls and hardcoding most of values..please let me know what you prefer

below the simplified version

I have refreshed G'MIC 3 times and it is not showing up. I looked in Testing > PhotoComix and it's just not there.

If I'm translating PC right, he forgot his password to his host site for G'MIC; it that's the case, then you have to copy the code and create a file called gmic and place it in the same directory where your G'MIC presets are and it's in a very obscure place depending on your OS O. For Win7 users it's located under your user account name\AppData\Roaming directory.

Can't be in Photocomix testing because is not in my source file
if you have a gmic file paste there, if not save as "gmic" without extension
(in both cases will show on top where are usually the fav)

Or wait till i don't recover the URL of my source file



No the password (hopefully) only the URL, i tried a dozens of sides when i had to change from Mahvin place, i forgot which i had chosen...it is a long time that i don't add or update filters

I tried a simplified version, to be simplified are only the controls for the optional post sharpening
I unified controls for Darkness and Lightness:
the Darkness/Lightness control now set the Darkness to the value chosen, the Lightness is 1/3 of the Darkness value



The 2 versions doesn't conflict let me know what you prefer

@ O, L (and everybody that may have already copied)

It was a typo in both, corrected now
i suggest to copy again

I've copied it but I don't know where to put it. I have no folders called roaming nor do I have any folders called gmic.

Perhaps David can reset your password, PhotoComix.

no problem of pw i just need to find the right url, i found already 5 sites with the same file

back to you... in linux the file should be just in your home, but you must chose in your file browser to visualize hidden files
you will have no a .gmic file , because is personal and so must be created,but you should see the others

PS i believe in linux the gmic files have still the dot before the name

I already have hidden files/folders selected. I found files named with gmic and, as you can see, some of the names in the Testing folder in G'MIC are showing. I didn't do the whole list but I think it's enough to show what I have in my home/o folder. There are no folders named gmic.

No i already tell you that the .gmic file exist only after you create it, it is for personal filters to be preserved by filters update


you may copy the code with a txt editor, and just save as .gmic there

It's there and it's not working. I tried refreshing even tho it really has nothing to do with local files.

It worked for me O by just pasting PC's code in a text file and renaming it .gmic
Then i just saved it to my home folder (rod).

Hi PC,
You're URL source for your external filters in G'MIC is actually set to :



I think that would be cool if you can update your sources with your new downscaling filter.
If you can't do it, please tell me about a new URL for your filter sources, otherwise, this means we have a dead link in G'MIC, and that wouldn't be a nice thing.

the site doesn't recognize me and don't let me in or recover the PW

I am not even sure it was my own account or my file was hosted by somebody in the gmic flickr group in his account there

This link may work ?
http://www.deviantart.com/download/6699 ... fu3pa.gmic

But on deviantart i can't fully control the file name : "_by_photocomix2-d5fu3pa" is added automatically out of my control, and i am not sure will not be changed when replacing the file.

No, you have to be able to ensure your URL won't change, and your location will be accessible by everyone. This looks like DeviantArt doesn't allow this.
Should I remove your 'websitehome' link ? Couldn't you provide a stable URL instead ? :p

Solved !..well it will be solved at soon Garagecoder will reply

He is hosting the file (i checked on http://www.flickr.com/groups/gmic/discu ... 374166402/ ..last 2 messages ) i already send him a pm

Upscale was not the goal ..but a very slight blur (really slight if the filter used for upscale because the blur is equal to the proportion between original size and desired size...so is less then 1 when upscaling ) followed by a slight dark halo sharpening almost always improve the look

Panic averted people! Filter update should now add the new filters, I've been a bit busy this past week so didn't notice the new stuff. Re-sent your ftp login details photocomix so you can update it yourself as well.

Thanks GC. hey PC; anyway possible to add a keep aspect ratio option (only then need a single slider)? Have to play with post sharpening feature, but I did get good results using wavelet sharpening plugin afterwars. No aliasing to boot. Good work.

I thought after I turned on my computer this morning it might work. Nada. I re-copied the code and saved it. Nada.
