Large formula with fn F3 template

[giammi56]

Dear all,

I am having troubles fitting a long formula in the usual template fn + F§. I am using this syntax:

R {"="} C ` B ` A {"="} newline {"="} 
left (  stack{cos γ` cos α - cos β` sin α` sin γ # -sin γ` cos α - cos β` sin α` cos γ # sin β` sin α } ``` stack{cos γ` cos α + cos β` sin α` sin γ # - sin γ` sin α + cos β` cos α` cos γ # -sin β` cos α} ``` stack{sin γ` sin β # cos γ` sin β # cos β}   right )

but the result doesn’t fit in the frame:

Usually it would automatically scale the formula, but something weird is happening. Does anybody have a clue?

There is no reason to autoscale the formula; it is an OLE object, not a picture nor a character. It is inserted “as is”.

What happens is clipping in the table cell.

When you type “fn”+F3, some macro is fired up to insert a 1-row 2-column table within the margins.The right cell is given a fixed 1,45 cm width, leaving the rest for the formula. Therefore, if your margins are too large, there is not enough room for the formula which gets clipped.

And worse, as usual with macro-driven feature in Writer, the macro adds direct formatting preventing centralized control over the appearances of formula numbering. This is why I prefer to handle numbers myself.

You didn’t mention the size of your margins. I assume they have a “fair” dimension. Considering changing the font size in the formula would make it less legible, a possible workaround is to allow this formula (and no other) to overflow in the margins.

• Put the cursor in the numbering cell and Table>Properties
• In the Table tab, set Alignment to Center
• Adjust Spacing Left to a negative value (something like -0,5cm or -1 cm)
• Check in Columns tab that column 2 is still 1,45 cm so that column 1 received all the added width

Thank you for your great explanation. I solved the issue removing the border padding and adjusting the column 2 size.
