Hello there!
I've written a small patch based on the gimp-2.4.0-rc2 sources which
implements a new gimp-text-fontname and gimp-text-get-extents-fontname
function for the PDB. In fact, I wrote this because I needed the
possibilities of adjusting letter/line spacing and indentation as well as the
possibilities of directly getting access to hinting and auto-hinting in my
gimp-ruby-scripts.
As I'm totally new to gimp development I don't really know if this was the
right place to implement, so I just wrote two new
functions gimp-text-fontname-new and gimp-text-get-extents-fontname-new
and put them just in the same files where I found the other old equivalent
functions. I hope my C knowledge wasn't that bad, but as gimp sources were
really well arranged, it didn't take me too long to get used to the syntax.
I would be happy about some feedback because I urgently need this feature in
the gimp.
Best regards
Marcus
