PHP Imagick不会添加ICC颜色配置文件

I'm working on a project where I've had to learn about color profiles a bit, still very much a novice. This code doesn't seem to be adding the icc profile:

$im = new Imagick;
$im->readImage('input.tif');

print_r($im->getImageProfiles('*', false));

$im->stripImage();
$im->profileImage('icc', file_get_contents('myprofile.icc'));

print_r($im->getImageProfiles('*', false));

Result:

Array
(
    [0] => 8bim
    [1] => icc
    [2] => xmp
)
Array
(
)

If I change the argument icc to any other string it appears in the output, but the file size doesn't change (not certain if it would).

$im->profileImage('testWhatever', file_get_contents('myprofile.icc'));

This shows testWhatever in the second print_r() output.

What could be the issue and how can I debug this? I've read nearly every post here about this topic, I'm happy to provide more information.

Debug notes, hopefully something here is useful:

  • Version: ImageMagick 7.0.7-11 Q16 i686 2017-11-12
  • PHP version 5.6.4
  • Tiff file is CMYK

    Figured it out thanks to a comment on the profileImage manual page:

    http://php.net/manual/en/imagick.profileimage.php

    Solution: Install LCMS delegates and recompile ImageMagick, you may need to remove and reinstall the PHP extension as well.

    If profileImage() seems to be doing nothing — and "inverted colors" during a CMYK > RGB conversion is a sign of this — check that ImageMagick has the lcms delegate available.

    From a command prompt:

    convert -list configure | grep DELEGATES

    If you don't see lcms in the list then Imagick won't do any color profile conversions, and won't give any warnings about this. In that case, install the Little CMS library ( http://www.littlecms.com/ ) and recompile ImageMagick.
