Thank you very much guys, I am gonna give it a try and let you know!

hi fmw42, Thank you for your quick response! There is no special algorithm, I would like to specify each RGB values for all 256 pixels of gradient.png and then clut. NetPBM looks like exactly the right solution I was looking for. Could you just tell me how to enter RGB values as 3 arrays and combine ...

Hello everyone! I would like to use -clut parameter to adjust color correction for pictures using a gradient image of 256x1. For making a standard gradient image without correction I use: convert -size 1x256 gradient: -rotate 90 gradient.png Since there are variation of different color correction I ...

Thank you guys.. :D I always assumed it might be possible to do that but didn't think that it would be that easy. ProfessorJerk I still need to pass seperate parameters (like resize/rotate/...) for each image so I think approach suggested by el_supremo works way I want it. Anthony thank you for ...

Hi everyone,, I am really thankful to be able to use ImageMagick in my software to render files. Currently I have created template files which contain reference to images + render settings. Depending on arguments mentioned in these template files software will call IM convert.exe several times ...

Fred 3 steps you mentioned are exact same 3 steps I had in mind. I was trying to make hald-clut image (in step 1) using: convert.exe HALD:8 c:\hald.jpg But it still doesn't work. Anthony HALD coder is apparantly not implemented in windows binaries of IM-6.6.2 and IM-6.6.3-0 ! I tried to make hald ...

Special thanks to Fred and Anthony for your quick responses. Fred I am not intending to let the user change curve in GUI. All I need is to perform same correction actions like old software does. So graph 2 1d LUT script is not what I am looking for. Hald could be indeed the solution I am looking for ...

This is a great honor to have maker of Fred's ImageMagick Scripts (so probably Fred himself) helping me out with this. I found links to that page so many times on internet and found very useful information there. As a matter of fact I have had a quick look at curves script before. Thank you for your ...

Hi everyone, I searched all over internet and still haven't found a solution for this challenge. I am dying to know how to implement color correction in the way we normally do it in Photoshop by using curves with a very basic bent graphic like shown in these pictures: http://www.dastan.net/papoola ...
