Hi, Fan I have extracted parameter from first paragraph in sample file
1 Spacing before paragraph 18pt in doc file 2 above-paragraph-spacing in SvxULSpaceItem: 360 3 line-spacing of said para in doc file: 12pt 4 line-spacing of said para in SvxLineSpacingItem:240 Seems that the value mapping works, Looking forward to your further response:) 2012/6/20 Fan Zheng <zheng.easy...@gmail.com> > Hi ZJ: > > Sorry, perhaps I missed something.
