Delegate library support not built-in

[yazinsai]

Hello, I'm using ImageMagick on a shared version of TMDhosting.

I am using a script that obtains the C,M,Y and K channel means from an RGB image. The command I am using to convert the image is shown below:

Code: Select all

convert -verbose "source.jpg" -profile "sRGB_v4_ICC_preference.icc" -profile "Photoshop5DefaultCMYK.icc" "cmyk.a.jpg"

The command didn't fail, but gave me the following warning:

convert: delegate library support not built-in `source.jpg' (LCMS) @ warning/profile.c/ProfileImage/945.

I then read the C,M,Y and K channel means using the command:

Code: Select all

identify -format "%[fx:mean.c]\n%[fx:mean.m]\n%[fx:mean.y]\n%[fx:mean.k]" "cmyk.a.jpg"

However, I noticed that the output values for the CMYK readings were MUCH lower than I expected:

0.091312
0.26802
0.338747
nan

Please let me know what I need to do to fix this with the host. I spent about an hour searching through the forum and found this relevant topic (viewtopic.php?f=3&t=14959), but didn't know what to recommend the server support team to do?

Thanks!

convert: delegate library support not built-in `source.jpg' (LCMS) @ warning/profile.c/ProfileImage/945.

It would appear that you are missing LCMS delegate library. You probably need to install that and then reinstall IM.

see

Do you see lcms listed when you do

convert -list configure | grep -i "delegates"

No, I get the following output:

DELEGATES bzlib fontconfig freetype jpeg jng png rsvg tiff x11 xml wmf zlib

So LCMS is missing then yeah?
