Issue with profiles after update to IM 7

[the-ninth]

Hi,

My website's server was previously using IM 6 but the hoster has now upgraded to IM 7. Since then some code that I used for profile handling does not work anymore.

With IM 6 I used the following command to export a color profile from a source file, strip away all meta data and then include the profile again:

convert source.jpg -write profile.icc -strip -profile profile.icc target.jpg

With IM 7 profile.icc still contains the profile, but target.jpg is without a profile. With IM 6, target.jpg contained the profile.

I have written a small test program to verify this: http://www.the-ninth.com/test/test.php

On my local test installation with IM 6.6 this still works, on my server (the one from the link above) it does not.

I already checked the porting guide (http://www.imagemagick.org/script/porting.php) but could not find anything related to profile handling.

Any hints on how to solve this would be highly appreciated!

Thanks!

Regards, Robert

On IM v7.0.2-5 under Windows 8.1, it works fine, both for "magick" and "magick convert".

I suggest you try with those two commands.

[the-ninth]

Thanks. Cannot finde the magick command on my server, have to check with the hosting company how I can access it. There is a /usr/bin/convert, but there is no /usr/bin/magick. Since I do not have full access to the server I cannot check myself.

In any case, with IM 7, should convert not be just an alias of magick?

What is your platform? On unix, the install should make convert a symbolic link to magick. However, there should be a magick command. I suspect your server people have install IM 7 in a different location such as /usr/local/bin.

What do you get from

/usr/bin/convert -version
/usr/bin/magick -version

and

/usr/local/bin/convert -version
/usr/local/bin/magick -version

and

convert -version
magick -version


or

type -a convert
type -a magick

[the-ninth]

OK, my bad, /usr/bin/magick actually exists. Version is 7.0.2-5 Q16 x86_64. /usr/local/bin/convert or magick does not exist. Using the commands without path gives me the same version.

In any case, switching from convert to magick does not solve the issue. I still don't get the color profile in the target file.

I suggest you post your input file to some place such as dropbox.com and put the URL here. Then we can test your command with your image.

If you change -write to +write, does it work?

[the-ninth]

With +write the result is the same.

The file can be found at: http://www.the-ninth.com/test/source.jpg

With IM 6.6 everything works as expected with the same source file.

Thanks for your support!

Works fine for me on IM 7.0.3-4 Q16 Mac OSX. See below where target.jpg contains the line:

Just installed ImageMagick 7.0.3-4 Q16 x64 on my home PC and there it works as well. So either it is something related to version 7.0.2-5 Q16 x86_64 or it has something to do with the setup of my web hosting server.

Is there a way to download 7.0.2-5 somewhere for Windows? I could only find 7.0.3-4 for download.

[fmw42]

As source or binary?

[the-ninth]

I'd need the binary.

[the-ninth]

try

Code: Select all

magick source.jpg +write profile.icc null:
magick source.jpg -strip -profile profile.icc target.jpg

Also tried this suggestion, but the result is the same. The first command correctly writes the profile, but still, after the second, target.jpg does not contain the profile. Even when I split it in three to separate the -strip and the -profile it does not work.

Code: Select all

/usr/bin/magick source.jpg +write profile_from_source.icc null:
/usr/bin/magick source.jpg -strip target_temp.jpg
/usr/bin/magick target_temp.jpg -profile profile_from_source.icc target.jpg 

So, whatever I do, the -profile parameter does not seem to work on my hosting web server.

Is there anything my hoster could have done wrong when installing ImageMagick? Does the -profile need any libraries to work, or something else that could be missing?

[snibgo]

I believe "-profile" needs LCMS. "convert -version" should list LCMS as a built-in delegate.

I believe "-profile" needs LCMS. "convert -version" should list LCMS as a built-in delegate.

Thanks for the hint, then that may be the issue. My hosting web server does not list LCMS in the delegates. Will ask my provider about it.
