推荐答案

您可能想编写一个由cronjob执行的bash脚本.因此，在定义的时间或定义的时间段之后，您会将rtf文件转换为jpgs.

尽管我不知道这是否可以满足您的程序化"需求..这是如何进行此转换的方法:

要转换rtf文件，请使用诸如图像之类的高级"功能，例如，您需要unoconv，这需要安装libreoffice.

You might want to write a bash script to be executed by a cronjob. So at a defined time, or after a defined period, you will have your rtf files converted into jpgs.

Though I don't know if this might satisfy your "programmatic" need .. here is how to do this conversion:

To convert rtf files contain "advanced" features like images, as in your case, you need unoconv, which requires libreoffice to be installed.

unoconv -f pdf "${input_file}"

否则，仅供参考，因为这不是您的情况，如果rtf文件仅包含文本，则可以通过使用级联转换(如p

Otherwise, just for reference because it's not your case, if the rtf files contain only simply text you can avoid the requirement to have libreoffice installed by using a cascade conversion like

// convert rtf to txt
unrtf --text "input_file.rtf" > "temp.txt"

// convert txt to pdf
enscript "temp.txt" -o - | ps2pdf - "temp.pdf"

// convert pdf to jpg
convert -quality 100 -append "temp.pdf" "output.jpg"

// remove temp files
trash "temp.txt" "temp.pdf" // or rm if you prefer
