How does copy() sample?
I'm smashing a 640x480 image down to 32x24. Then I try to display the smashed image at a large size to show the effect.
When it's making the large image smaller I'd like it to average the pixels, maybe even weighted by distance.
When it's making a small image larger I'd like it to sample absolutely (crisp edges between color boundaries).
Is there a setting I didn't see to enable this behavior?
I'm using it for this: https://instagram.com/p/3dOVB-IfEX/ 2mx1.5m RGB LEDs. Trying to preview the output before I connect to the DIY jumbotron.

do you use

?
It is hard to tell what you want without seeing your code.
I only use copy. Code is here: https://github.com/i-make-robots/LEDWall/blob/master/Processing/screenCapture/screenCapture.pde
