Re: Creating a new back-end for Pango

[James Hu <jamesyjhu gmail com>]

Hi,
As UIFont is only a subset of Cocoa Text, it does not contain any of
the advanced text layout capabilities available in Pango. The next best thing below UIFont is very simple glyph displaying in Core Graphics/Quartz, and can't be used for displaying anything but the most basic latin scripts. Thanks again!

Hi,
I'm trying to port Pango to the iPhone. The iPhone doesn't have ATSUI,
but instead uses UIFont, which is a subset of the OS X's Cocoa Text
system. And due to iPhone's memory size restraints, I'm trying to avoid
including Cairo into the mix and draw directly with Core Graphics (which
is what Cairo uses anyways).

Why would you want to use Pango then?

Do you guys have any pointers on what classes need subclassing, and what
hooks are available in Pango to include a new backend? Any help would be
much appreciated. Thanks!
