Re: [sdljava-users] Bug in SWIG_SetPixelData32 method / Suggestion

[Ivan Z. G. <iva...@ya...>]

Greetings,

Sorry for the delay!  I finally got off my but and got everything 
working on my system so I can develop again.  Everything is 64 bit for 
now though as I didn't get a 32 chroot working yet, but alas, that will 
have to wait for another time.

I have applied the fix below to HEAD.

Cheers,
