如果我运行此命令，
convert -limit memory 2071963648 -quality 100 -alpha off -density 165% -scene 1 infile.jpg outfile.png
转换运行没有任何问题。
但是，如果我添加+profile "*"，
convert +profile "*" -limit memory 2071963648 -quality 100 -alpha off -density 165% -scene 1 infile.jpg outfile.png
这个过程被杀了。
以下是dmesg

我不知道为什么-strip会导致ImageMagick崩溃，但作为替代方案，您可能会尝试这样convert image.jpg -strip output.jpg
。
string[] files = { "f1.txt", "f2.txt" };
var allLines = files.SelectMany(i => System.IO.File.ReadAllLines(i));
System.IO.File.WriteAllLines("new.txt", allLines.ToArray());
它会删除所有个人资料和评论的图像。
