Re: How do I get X, Y pos and PangoLogAttr of each glyph in a rendered string?

This python code is very helpful.  How difficult would it be to add an
extra function that draws boxes around words?



I have code that does a pretty good job of finding words, but still
seems to bork on some examples.  http://pastebin.com/gdQrDXFm

In that same code, I have a function that can fill Cairo paths word by
word.  It is far from perfect, but works some of the time. It is only
built for text going from left to right.   Still, I was wondering if
someone had an idea why it segfaults if I set_markup on the layout
instead of set_text.  How does set_markup change the layout soe that I
cannot proceed as I am doing? 

I've been working on this word-by-word algorithm for over a year now (on
and off as I have time).   So, any suggestions you might have
would be greatly appreciated.
