PHP Imagick 不会添加 ICC 颜色配置文件

PHP Imagick won't add ICC color profile

我正在做一个项目,在这个项目中我不得不学习一些颜色配置文件,但仍然是一个新手。此代码似乎没有添加 icc 配置文件:

$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));

结果:

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

如果我将参数 icc 更改为 any 其他字符串,它会出现在输出中,但文件大小不会改变(不确定是否会改变) .

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

这在第二个 print_r() 输出中显示 testWhatever

可能是什么问题,我该如何调试?关于这个主题,我几乎阅读了这里的所有 post 篇文章,我很乐意提供更多信息。

调试说明,希望这里的内容有用:

convert -list configure

感谢 profileImage 手册页上的评论:

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

解决方案:安装LCMS委托并重新编译ImageMagick,您可能还需要删除并重新安装PHP扩展。

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.
