[PD] GEM - The Relationship Between [translate] and [rectangle]?

[J bz]

Hi Max,

Cheers for the quick response.

tbh, pix_film is the reason I know the pixel dimensions already:)

Would you mind explaining in a little more detail - which objects and how?

I am unclear on the relationship, say, between [rectangle 3 2] and 320x240
pixels, and again how that corresponds to [translate] and the numbers I am
putting in the inlets 2 and 3 of translate.  For example when I increase the
2nd inlet of translate (magnification? sorry I'm not in front of pd atm) my
2nd avi movie moves in a north easterly direction from within the gemwin and
I don't understand why?

Kind regards,

Jb
