其中

WPS的Word转PDF部分失败

要把

1
oleutil.MustCallMethod(document, "SaveAs", pdfPath, 16).ToIDispatch()

改为

1
oleutil.MustCallMethod(document, "SaveAs2", pdfPath, 17).ToIDispatch()

这样就可以保证转换过都没有问题了。

调用方式

wps2pdf.exe wps "D:\\Tools\\Docs\\01.docx" "D:\\Tools\\Docs\\pdf\\01.pdf"
wps2pdf.exe office "D:\\Tools\\Docs\\01.docx" "D:\\Tools\\Docs\\pdf\\01.pdf"
