I´m play with Pd a few months ago and I have a doubt with GEM. I would like to know how works [pix_data] object, because I follow the example patch but does´nt work. I need to find the way to "read" the data of any pixel (colours, mostly), at the position of the mouse pointer in the gemwin. The question is:
-Where is the error in my patch (anexed)?
-Is another way to obtain the pixel data in the gemwin (any pixel)?
Thank´s for your time and help. Nice day.
