PHP Imagick不会添加ICC颜色配置文件 [英] PHP Imagick won't add ICC color profile
问题描述
我正在做一个项目，我不得不稍微了解一下色彩配置文件，但仍然是一个新手.这段代码似乎没有添加icc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));
结果:
Array
(
[0] => 8bim
[1] => icc
[2] => xmp
)
Array
(
)
如果将参数icc更改为 any 其他字符串，它将出现在输出中，但文件大小不会改变(不确定是否会改变).
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'));
这在第二个print_r()输出中显示testWhatever.
This shows testWhatever in the second print_r() output.
可能是问题所在，我该如何调试?我几乎在这里阅读过有关该主题的所有文章，很高兴提供更多信息.
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.

推荐答案
在profileImage手册页上的注释使它得以解决:
Figured it out thanks to a comment on the profileImage manual page:
http://php.net/manual/zh-CN/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.
Solution: Install LCMS delegates and recompile ImageMagick, you may need to remove and reinstall the PHP extension as well.
如果
profileImage()似乎什么都不做-并且在CMYK> RGB转换过程中出现反色"是这种现象的迹象-请检查ImageMagick是否具有可用的lcms委托.
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.
在命令提示符下:
convert -list configure | grep DELEGATES
如果您在列表中没有看到lcms，那么Imagick将不会做任何颜色 个人资料转换，不会对此发出任何警告.在那里面 情况下，安装Little CMS库( http://www.littlecms.com/)，然后 重新编译ImageMagick.
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.
