Imagemagick 为什么选择此参数'+；简介*&引用'；被杀了？

如果我运行这个命令

 convert  -limit memory 2071963648 -quality 100 -alpha off -density 165% -scene 1 infile.jpg outfile.png

转换运行时没有任何问题

但是，如果我添加

+profile“*”

进程被终止

这里是来自

dmesg

我正在使用这个版本的ImageMagick

$ convert -version

在Ubuntu14.04.1上，我不知道为什么

+profile

会导致ImageMagick崩溃，但作为一种替代方法，您可能希望尝试这样的

-strip

convert image.jpg -strip output.jpg

---

它会剥离所有配置文件和评论的图像。

您是否尝试过使用

-strip

而不是

+profile

？另外，使用

JPEG

-strip

修复了我的问题的

-scene 1

和

-alpha off

的要点是什么。我使用

-scene1

等转换其他文档类型。只需通过mistake@MarkSetchell你可能想把你的评论变成一个答案，这样我就可以投票并接受了！很高兴你成功了。
