bugdoc (DOC)

The attached document has a table, which should fit in the first column of page 1 (as in Word). It does not fit, because it has text grid switched on, and line height of text grid is bigger in Writer that it is in Word. 

I found the relevant code location, but I do not know how to interpret values from the doc better. nLinePitch*=0.9 worked well, but...

@Caolán: could you please advise?

Back in the day when we first implemented the text grid I suggested we should have the same text grid rules as word (whatever they are) for ease of interoperability, but the powers that be said they wanted a text-grid that was "better" than words and so we have different rules for it, which is a frustrating nightmare.

The table confuses things, but if you remove it and compare word against writer for 15 lines per page (writer: format page->text grid with cjk features enabled word: page setup->document grid) and put 15 lines into word and writer for this doc then word fits 15 lines into the page and writer fits 14.

I remember just giving up and settings things so that the numbers are the same in word and writer wrt lines per page and base text size. I don't think it's as simple as just scaling the font size by 0.9 (but maybe it is) https://wiki.openoffice.org/w/images/1/1c/Text_Grid_Enhancement_for_CJK.odt which has some details on what's wrong with our grid that *might* be useful.

You probably need to find the code in writer that calculates the grid and see how it calculates it in order to feed it numbers that will make it behave like word. It might be that to get the same layout as word you have to add/subtract page margins and/or header/footer heights or something like that.
