[Rubycocoa-talk] ATSUI API

[Duncan M. <du...@on...>]

Hi

First thanks for RubyCocoa. As the author of Rococoa, which does a  
similar job for Java, I really appreciate what you've done.

I'm trying to access Apple Type Services for Unicode Imaging (ATSUI)  
through RubyCocoa - in order to measure text before I lay it out.

I need to call, for example - ATSUCreateStyle

This is defined in ATSUnicodeObjects.h, which seems to be found in

/System/Library/Frameworks/ApplicationServices.framework/Frameworks/ 
QD.framework

I'm having trouble working out how to gain access to this API.

When I wanted to use CoreIO I used

require_framework '/System/Library/Frameworks/ 
ApplicationServices.framework/Versions/Current/Frameworks/ 
ImageIO.framework'

So I expected that

require_framework '/System/Library/Frameworks/ 
ApplicationServices.framework/Versions/Current/Frameworks/QD.framework'

would work, but I get NoMethodError: undefined method  
`ATSUCreateStyle' when I try to call the function.

Can anyone please point out what I'm doing wrong?

Thanks in anticipation
