magick命令给出无法打开图像的错误 [英] magick command gives unable to open image error

问题描述

我正在尝试从命令提示符下运行以下命令，但出现以下错误:

I am trying to run below command from my command prompt and it gives me following error:

magick billadd1.jpg -type TrueColorAlpha billadd2.jpg -type TrueColorAlpha \( -clone 0,1 -compose difference -composite -morphology dilate disk:10 \) \( -clone 0 -fill yellow -colorize 100 -channel a -evaluate set 50% +channel \) \( -clone 0,3,2 -compose over -composite +write 1.jpg \) \( -clone 1,3,2 -compose over -composite +write 2.jpg \) null:

magick: unable to open image '\(': No such file or directory @ error/blob.c/OpenBlob/3537.

magick:此图像格式''@ error/constitute.c/ReadImage/562没有解码委托.

magick: no decode delegate for this image format `' @ error/constitute.c/ReadImage/562.

此外，如何使用im4java从Java运行此命令?

Also, how to run this command from java using im4java?

请注意，我正在使用imagemagick veriosn7

推荐答案

Windows语法不同于Unix/Linux语法.您的命令当前使用Unix/Linux语法:

The Windows syntax is different from Unix/Linux syntax. Your command is currently in Unix/Linux syntax:

magick billadd1.jpg -type TrueColorAlpha billadd2.jpg -type TrueColorAlpha          \
    \( -clone 0,1 -compose difference -composite -morphology dilate disk:10 \)      \
    \( -clone 0 -fill yellow -colorize 100 -channel a -evaluate set 50% +channel \) \
    \( -clone 0,3,2 -compose over -composite +write 1.jpg \)                        \
    \( -clone 1,3,2 -compose over -composite +write 2.jpg \) null:

转换为Windows时，可能会变成:

Which, when converted to Windows, probably becomes:

magick billadd1.jpg -type TrueColorAlpha billadd2.jpg -type TrueColorAlpha ^
   ( -clone 0,1 -compose difference -composite -morphology dilate disk:10 ) ^
   ( -clone 0 -fill yellow -colorize 100 -channel a -evaluate set 50%% +channel  ) ^
   ( -clone 0,3,2 -compose over -composite +write 1.jpg ) ^
   ( -clone 1,3,2 -compose over -composite +write 2.jpg ) null:

因此，从Linux到Windows的规则如下:

So, the rules are something like this to go from Linux to Windows:

• 在括号前删除反斜杠
• 将反斜杠的行继续符更改为脱字号(^)
• 将任何百分号加倍
• 将任何单引号更改为双引号

• remove backslashes before parentheses
• change backslash line-continuation character to caret (^)
• double up any percent signs
• change any single quotes to double-quotes

此处有一些更详细的注释.
