I tried installing separate plug in for Gimp, but I failed. Then, I installed another application: Krita, but has some stability problems. What do you suggest?
I use OsX.
You could do it with matlab (or whatever the language)
f = imread('ngc6543a.jpg');
f = im2double(f);
k = 1-max(f,[],3)
c = 1-r;
m = 1-g;
y = 1-b;
CMYK = cat(3,c,m,y,k);
imwrite(CMYK,'cmykimg.TIFF');
You could also used imagemagick with the commande line
magick imgrgb.png -colorspace RGB -colorspace CMYK imgcmyk.tiff
Hi Maxime, thank you!
Actually the command was: convert mgrgb.png -colorspace RGB -colorspace CMYK imgcmyk.tiff
I didn't know this tool, it could be very useful for a lot of other options too!
'convert' is for previous version of imagemagick.
Yes it is a usefull tool. I also use it to make .GIF for my presentations.
Mmmm ... I installed it by macports v. ImageMagick-6.9.6-2 and only convert was working ...
