montage of CYMK pictures tagged as sRGB

[reactormonk]

I downloaded http://www.astralvault.net/games/SA/Car ... tedPDF.rar and converted the images of one batch with

Code: Select all

convert -density 600 xCreuss.pdf creuss%d.jpg

which worked well.

Code: Select all

$ identify creuss0.jpg
creuss0.jpg JPEG 1133x1658 1133x1658+0+0 8-bit CMYK 1.476MB 0.000u 0:00.000

But

Code: Select all

montage creuss0.jpg -colorspace CMYK -geometry 1133x1658+0+0 -clone 0,0,0,0,0 creuss_bg.jpg

produces a file with

Code: Select all

$ identify creuss_bg.jpg 
creuss_bg.jpg JPEG 3399x3316 3399x3316+0+0 8-bit sRGB 4.595MB 0.000u 0:00.009

sRGB tag instead of CMYK.

I do not believe that montage supports CMYK colorspace. So you probably need to convert to sRGB, then montage, then convert back to CMYK. Best to use profiles if possible.
