Committed a compiling version. you forgot the name of the class in front of the implementation of the member function in your cpp. Added getclass and get requirements. Add in getRequirements what you need. Please try to structure a bit more the code. avoid to put everything inside the applyFilter function, that shoiuld be mostly a switch for all the incoming possible actions. Try to keep it short. cheers p. skunkwerk wrote: > i've committed the version of the filter_texture code i was trying to > compile. can anyone try to compile this? i'll keep working on it > > imran > > On Thu, May 8, 2008 at 11:08 AM, skunkwerk <sku...@gm... > <mailto:sku...@gm...>> wrote: > > thanks Paolo, that solved the immediate problem.
