[Rubycocoa-talk] Alternative to NSGraphicsContext graphicsContextWithGraphicsPort:flipped:

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

Hi

I'm writing PDF's with RubyCocoa, and want to set the current graphics  
context to a PDF context from CGPDFContextCreateWithURL so that I can  
draw on it.

Essentially my code says (sorry, ObjC folks, Ruby follows)

@pdf_context = CGPDFContextCreateWithURL(pdf_url, CGRectMake(0, 0,  
100, 100), nil)
.....
NSGraphicsContext.saveGraphicsState
nscontext =  
NSGraphicsContext 
.graphicsContextWithGraphicsPort_flipped(@pdf_context, true)
NSGraphicsContext.setCurrentContext(nscontext)

My problem is that graphicsContextWithGraphicsPort:flipped: crashes  
RubyCocoa. It's a known issue, and has been fixed, but not shipped in  
10.5.7

Can anyone suggest any workarounds that could get the pdf_context  
current?

Thanks in anticipation
