linux Imagemagick将PDF转换为JPG的问题

The system I'm using uses the linux utility convert to convert pdfs to jpgs. My box gives me the following error.

我正在使用的系统使用linux实用程序转换将pdf转换为jpgs。我的框给了我以下错误。

>$ convert Badge-1114044091.pdf Badge-1114044091.jpg
convert: Postscript delegate failed `Badge-1114044091.pdf'.
convert: missing an image filename `Badge-1114044091.jpg'.

But the production machine does not. According to

但生产机器没有。根据

>$ convert -version

my version is the same as the prodution machine. I'm not sure exactly how to check if postscript needs to be updated. Not really a huge linux guru.

我的版本与生产机器相同。我不确定如何检查postscript是否需要更新。不是一个巨大的Linux大师。

EDIT: Upon suggestion, I checked Ghostscript. The following was already installed.

编辑:根据建议,我检查了Ghostscript。已安装以下内容。

>$ gs -version
ESP Ghostscript 8.15.3 (2006-08-25)

Install GhostScript.

ImageMagick (the 'convert' utility) doesn't actually convert PDFs; it invokes GhostScript using an arcane command like

ImageMagick('convert'实用程序)实际上并不转换PDF;它使用类似的奥术命令调用GhostScript

gs -q -sDEVICE=jpeg -dBATCH -dNOPAUSE -dFirstPage=1 -dLastPage=1 -r<OUTPUT RESOLUTION> -sOutputFile=<OUTPUT>.jpg <INPUT>.pdf 2>&1

You might want to try that command directly if you want more control.

如果您想要更多控制,可能需要直接尝试该命令。
