<ul></ul><p>I tried ImageMagick 7.0.9-24 Q16, but still got the error.<br />No error occurs when adding the "+profile icc", "-strip" or "-quiet" parameter.</p>
<p>Adding info:<br />Ghostscript v9.21 or earlier got no errors, however v9.22 or later got errors.</p>

<ul></ul><p>The warning successfully reproduced with ImageMagick 7.0.10-14 and GhostScript 9.52. But is it OK to always remove ICC profile?</p>

<p>I don't know the side effects of adding the option "+profile icc".<br />I suggest adding the "-quiet" option instead of "+profile icc".<br />The "-quiet" option has the same effect.</p>
