问题描述

如何将以下命令附加到ImageMagick的单个命令中?

How would I append the following commands into a single command for ImageMagick?

convert -size 1024x1024 xc:none -draw "roundrectangle 0,0,1024,1024,40,40" png:- | convert AppStore.png -matte - -compose DstIn -composite [e-mail]
convert -resize 50% [e-mail] [e-mail]
convert -resize 50% [e-mail] [e-mail]
convert -resize 50% [e-mail] Logo.png

推荐答案

我认为您可能想要这样的东西:

I think you probably want something like this:

convert AppStore.png -matte                                                 \
   \( -size 1024x1024 xc:none -draw "roundrectangle 0,0,1024,1024,40,40" \) \
   -compose DstIn -composite -resize 50% -write MPR:basic                   \
   \( MPR:basic -resize 50% -write [e-mail] +delete \)                   \
   \( MPR:basic -resize 25% -write Logo.png    +delete \)                   \

或者如果您想避免使用MPR(内存程序寄存器)，则执行以下操作:

Or this if you want to avoid the MPR (Memory Program Register):

convert AppStore.png -matte                                                 \
   \( -size 1024x1024 xc:none -draw "roundrectangle 0,0,1024,1024,40,40" \) \
   -compose DstIn -composite -resize 50%                                    \
   \( +clone -resize 50% -write [e-mail] +delete \)                      \
   \( +clone -resize 25% -write Logo.png    +delete \)                      \
