Hello there,

I am using Gimp 2.9.3 downloaded from http://www.partha.com/ and I am looking for a script to change the Color Temp of a layer. I have founded this script "colortemp" and installed it but unfortunately it's not working with my version of Gimp.

Error Messages are:

Error: eval: unbound variable: RED-LUT

Plug-In 'Convert Color Temperature' left image undo in inconsistent state, closing open undo groups.

The window of this script is:

Script URL: http://registry.gimp.org/node/73


My goal is to get this result which is a photo of my screen :

(Left with Color Temperature changed - Right side: Original colors)

I have noticed that some of my artworks are more beautiful with the soft SunsetScreen which change the colour temperature of my screen on night :

I have noticed the new option Color Temperature of Gimp 2.9.3 but the result is all the time too dark.

Thanks,
Vincent.
Ok guys, this script is working fine with Gimp 2.8.14 and I can get exactly what I was expected for. The same result of the SunsetScreen soft.

But I can't do it to a specific layer as I can't make a .xcf file with Gimp 2.9.x and open it with Gimp 2.8.x.

So, my question is, how to make this script (http://registry.gimp.org/node/73) works with Gimp 2.9.X which is the main version of Gimp I use?

Thanks again,
Vincent.
1. This in reply to first post

You could always try and ask the script author for an update - look at the top of the script for the contact.

Otherwise - are you really using Gimp 2.9.3? or 2.9.5 If the former you should get the latest and greatest from Partha.

G'mic looks to have a close match to your example, looks a bit simplistic but this in automode. screenshot http://i.imgur.com/yzjm9lG.jpg

Using Gimp 2.9.5 (linux) and gimp-gmic2

Does the Partha version have the compatibility option in the save dialog? It should have.

Yes, I should try to contact the author of this script.

I didn't thought about G'mic because there are I think too many stuff and it's not easy to check all of them to see if there will be the expected result.

Indeed, I could try the Color->Temperature of G'mic but without the same result of SunsetScreen, and yet even if I told I could get the same result with the script colortemp, not exactly actually.

I have to check again, and it's not easy. I have to check with and without SunsetScreen each time. Wink

Maybe I should try to get something I like with G'mic instead of trying to get what I get exactly with SunsetScreen activated...

Thanks again,
Vincent.
@ LondonUK371 I case you ever come back

I confess, I know didley-poop about Scheme. I do not know why "colour"-LUT does not return a value in Gimp-2.9.5 It might be a bug.

A little gentle alteration and attached might work for you. Remember to unzip it. 
If your Partha Gimp 2.9.5 runs with --pdb-compat-mode=off then expect to see 'deprecated procedure warnings' However you should still get a result.

RED-LUT etc are constants from beyond the dawn of time and had been deprecated before GIMP 2.6 in favour of HISTOGRAM-RED, HISTOGRAM-GREEN and HISTOGRAM-BLUE
Kevin - Thanks for the clarification. I suspect that there be more than a few old scripts and plugins that will fall by the wayside even with a compatibility mode.

If the OP can find a suitable equivalent g'mic filter then there is always the option to save the filter and settings as a 'fave' saving time searching and entering any variables.

Yes I'm still there Wink

Thanks a million for the submit of the corrected script. It's working like a charm with my version of Gimp 2.9.3.

As you mentioned, I have the 2 warnings you're talking about:
Code:
WARNING: Plug-In "script-fu.exe"
(C:\Program Files\Gimp-2.9\lib\gimp\2.0\plug-ins\script-fu.exe)
called deprecated procedure 'gimp-curves-explicit'.
It should call 'gimp-drawable-curves-explicit' instead!


Code:
WARNING: Plug-In "script-fu.exe"
(C:\Program Files\Gimp-2.9\lib\gimp\2.0\plug-ins\script-fu.exe)
called deprecated procedure 'gimp-hue-saturation'.
It should call 'gimp-drawable-hue-saturation' instead!

But it's working very fine!

Thanks again for your share Wink

I wanted to submit this forum thread on a comment of http://registry.gimp.org/node/73 but unfortunately I can't create an account:

If someone has already an account on http://registry.gimp.org/ to share rich2005 scm update, that would be nice.

You can also contact the author, see http://luca.dealfaro.org/photography/Colortemp

However, since he hasn't updated the page since 2009, maybe he is no longer interested. But anyway I suspect that the right script fom 2.9 could be very different (16/32 bit processing, and "Linear light").

Yes, I sent him an email. Maybe he will update his script according to the upload of rich2005.
