I'm interested in using Pango to set type in OpenType fonts to be saved as
PNG images. I've done some googling and I can't find any examples on how
to use the library or pango-view to do this without GTK. The idea is to
use either pango-view or the Pango Ruby wrapper to convert text into PNGs
on the fly from a linux server that's not running gtk, for use as titles
in web pages.
I've got pango-view installed, but when I run it I get:
% pango-view -q --text "hi there" -o hi.png

Hello Joshua,

I wrote something exactly for this a while back, but never got around to
publish it. I just uploaded it to Launchpad for you:

Dude, just hack pango-view to do what you want.

There's a README file telling you how to use it. Basically it's just his:

   $ render-text-to-image \
     --font='Georgia' \
     --size=48 \
     --text-color='#eee' \
     --background-color='#000' \
     --text='Hello, world!' \

It also supports transparency, margins, and some simple markup.

pango-view from the just-released pango 1.24.0 does all that:

$ pango-view \
  --font 'Georgia 48px' \
  --foreground '#eee' \
  --background transparent \
  --text 'Hello, world!' \
  --output hello.png \


Good luck, and let me know if you have any comments!
