Constructor & Destructor Documentation
| fp_Column::fp_Column | ( | fl_SectionLayout * | pSectionLayout | ) |
Create column
- Parameters:
-
pSectionLayout Section layout type used for this container
I suspect BIDI does not work with multiple columns since the leader would then have to be the right-most column.

| void fp_Column::layout | ( | void | ) |
Layout lines in the column
This function iterates over the lines in the column and computes their screen position from their accumulative heights in layout units.
Since this code accumulates fractions of the conversion process, the difference between Y positions of two lines may differ from the pre-computed height of the upper line. This is due to simple rounding errors and general lack of precision (screen coordinates are integer while the computation yields fractions).
To make XY/position conversion precise, remove the gaps by updating the line heights. Note that the line heights get updated next time there's a line lookup - so this does not in any way affect layout, only the precision of the XY/position conversion code.
Sevior: I put in the 0.5 to deal with truncation errors and the +1 to deal with the last line.
