php - ImageMagick bash 脚本问题

Question

// This works
convert ${path}${dst} -crop ${crop} ${path}${dst}

// but when changed to this, it fails
convert ${path}${src} -trim ${path}${dst}
convert ${path}${dst} -crop ${crop} ${path}"pdf_"${dst}

我做错了什么？

Answer 1

改变这个:

convert ${path}${dst} -crop ${crop} ${path}"pdf_"${dst}

对此:

convert ${path}${dst} -crop ${crop} "${path}pdf_${dst}"

帮忙？
