ImageMagick's convert tells me: no images defined

I tried to execute following command:

$ convert 1.png -filter 'Jinc ( +clone -negate -morphology Distance Euclidean -level 50%,-50% )' -morphology Distance Euclidean -compose Plus -composite -level 43%,57% -resize 12.5% 1.png

It tells me:

convert: no images defined `1.png' @ error/convert.c/ConvertImageCommand/3187.

but it is exists! I tried to execute that command with the debug option enabled:

$convert 1.png -filter 'Jinc ( +clone -negate -morphology Distance Euclidean -level 50%,-50% )' -morphology Distance Euclidean -compose Plus -composite -level 43%,57% -resize 12.5% 1.png -debug all

I get this output: http://pastebin.com/gsw7KszH

What's wrong with my ImageMagick's configuration? I use the latest macOS.

您可以尝试在复合运算符之后指定文件名，如下所示：

$ convert 1.png 
   -filter 'Jinc ( +clone -negate -morphology Distance Euclidean -level 50%,-50% )' 
   -morphology Distance Euclidean 
   -compose Plus 
   -composite 1.png 
   -level 43%,57% 
   -resize 12.5% 1.png
