Linux中使用命令列方式呼叫openoffice服務將word檔案轉為PDF

測試安裝之後的openoffice用命令將docx檔案轉換為PDF

需要一份python的指令碼程式，因為轉換需要通過py程式去呼叫api處理，將下面程式儲存到topdf.py檔案：

# PyODConverter (Python OpenDocument Converter) v1.1 - 2009-11-14
#
# This script converts a document from one office format to another by
# connecting to an OpenOffice.org instance via Python-UNO bridge.

將檔案儲存到program目錄下面，然後就可以執行轉換命令了：

[[email protected] program]# ./python topdf.py /opt/openoffice4/test.docx /opt/openoffice4/test.pdf

同樣的命令也可以轉換其它格式的檔案，轉化出來的檔案格式會有變化或丟失
