[GEM-dev] Output two images from pix_ object

[Matthias Kronlachner]

hi!

you can find an example how to do two outputs from pix_ object in my 
pix_freenect external.
http://www.matthiaskronlachner.com/wp-content/uploads/2011/11/pix_freenect_0.03.zip

i made an additional inlet and outlet for gemstate plus the methods that 
get called, 2 pixBlock and an additional GemState.

so the pieces of code that are interesting:
constructor:
   m_depthinlet  = inlet_new(this->x_obj, &this->x_obj->ob_pd, 
gensym("gem_state"), gensym("depth_state"));
   m_depthoutlet = outlet_new(this->x_obj, 0);

setupCallback:
   class_addmethod(classPtr, (t_method)(&pix_freenect::renderDepthCallback),
                   gensym("depth_state"), A_GIMME, A_NULL);

-> renderDepthCallback() calls the rendering method for the second 
output -> renderDepth(int argc, t_atom*argv);

the tricky thing is how to deal with the pointers from GemState and how 
to get them out of argc arguments (at least for me it was...)


so if you are still interested have a look at the code and ask if 
questions rise.
