Determining multi-line text height, few more questions

[atotic]

Hi,
I am doing a voting ballot layout project, and would prefer to use
Prawn. I started off with a pdflib. Coding in a mixed C/Postscript
style in Ruby is a mindwarp. Prawn has potential, and our release
schedules line up.

I've had some trouble finding docs for a few things I need to do:

1) How do you measure height of a multi-line text string? I am doing
programatic page layout, and need to know heights of multi-line
strings for a given width.

2) Can you go back and draw on older pages in a document. This would
come in handy for generating "page 1/5" type information.

If this stuff is not there, I am not shy at implementing it, would
love to get some hints about implementation.

Thanks,

Aleks

Should be able to use height_of()

You'll be able to do this in a minimal fashion in 0.6, which I'll
release Sunday.
All of the underlying mechanics are there, we just need to flesh out
the details.
