PF_GET_PIXEL_DATA8 cannot get x y posision pixel?

I'm trying to get output's x y position pixel by using PF_GET_PIXEL_DATA8 in function used in iterate.

The second parameter is a hint? I don't understand much.

honest to god, i don't understand it either. it seems to fetch the base address of an effect world's image buffer.

you can achieve the same doing (assuming you know the4 world type, and cast the correct pixel type):
PF_Pixel *p = (PF_Pixel*)effectWorld->data;
