I want to find a way to convert Microsoft's word to PDF on linux. My idea is to read each word, picture, or table first, and then write their structure into the PDF document. But when I read the format of the document and write it to PDF, only the pictures can be written and the styles are completely different from those in the document. I would like to ask a kind person if you have any experience in this field. Please give me some advice or guidance. Thank you!
