I find it best, when asking/[being
asked] for help, it is best to accurately describe the problem,
rather than a problem in a solution, unless I have a very firm
belief that my current solution, is my best solution. I don't
know of an answer to your question about the white space, but if
you are trying to render identical pages across a variety of
mediums, it is best to just display a picture. Flash was a great
idea in solving this problem, but flash pages weren't/aren't
search engine crawl-able, but neither are images. Anyhow, I hope
this was./[will be] helpful.

retrieve the cap height. Is something thats possible to retrieve?
it doesn't appear as though that metric is listed on the tutorial
page (unless it's listed as something else) and I've tried to read
through the api's and can't find any mention of it. I've also
searched through the mailing list archives and couldn't find any
info. Thanks again for the help and your patience.

You mean
you want identical line spacing across different browsers
and across different operating systems? And you are not
getting that?

this question is somewhat juvenile. I'm developing a
web application and noticed that the rendering that is
happening for certain fonts in chrome is very different
than how some proprietary layout tools are rendering the
same font. This causes an issue for me as I'm trying to
get the rendering to be somewhat identical. I've been
trying to use the free type library to pull out some
metrics to see if I could figure out what the rendering
engines are doing differently and if I could account for
this difference. What I'm seeing is that for some
fonts, and for this example specifically Patua-one,
there appears to be a lot of white space from the top of
the text within a glyph to the top of the bounding box
(vertical spae). In layman's terms, there is a lot of
white space in this font and that's the way it's been
designed I suppose. However, it appears some programs
will remove this extra space when rendering the font but
others dont. So, I suppose my question boils down to,
is there a way to determine how much white space is
present and/or are there specific font metrics that
specify this? I've read through the online docs and
have played with the api but was unable to find
anything. So my next approach was then to render a
character using the gd library and see if I could detect
the pixel width based on color. Unfortunately it looks
like the gd library that php is using is removing this
padding and therefore my calculations are off.
Appreciate any help in this matter Thanks very much,
here is a simple text drawing of the space I'm trying to
describe:
