如何在ImageMagick中使用输入文件名? [英] How do I use the input filename in ImageMagick?

问题描述

根据ImageMagick文档，我希望这样:

According to the ImageMagick documentation, I would expect this:

convert fountain-pen1.jpg fountain-pen2.jpg handwriting.jpg  -resize 400x400\>  -set filename:f '%t_smol.%e' '%[filename:f]'

得出fountain-pen1_smol.jpg fountain-pen2_smol.jpg handwriting_smol.jpg.

相反，它只会创建fountain-pen1_smol.jpg.

我在做什么错了?

我也尝试过使用*.jpg来得到相同的输出.

I've also tried with just *.jpg which results in the same output.

convert -version

推荐答案

Mmm ...有时您需要使用

Mmm... sometimes you need to give ImageMagick a hint to create more output files than it is expecting to, using +adjoin:

convert fountain-pen1.jpg fountain-pen2.jpg handwriting.jpg  -resize 400x400\>  -set filename:f '%t_smol.%e' +adjoin '%[filename:f]'

如果您在文件名中放入%02d或类似名称，它会猜测是否成立，但对于您的用例却不知道.

It guesses this if you put a %02d or somesuch in the filename, but doesn't know that for your use case.
