Scales down a picture by a specified amount. The value defines the scale factor. A pack object allows you to vary the horizontal and vertical values independently. In the example above, inlet 0 of [#pack] varies the image on a vertical axis, inlet 1 of [#pack] varies the image on a horizontal axis. Scales down picture by specified amount. (See scale factor above) grid((factor/y) (factor/x) channels) factor is optional (default is 2). "smoothly": does the downscale by averaging each block of pixels. omitted: does the downscale by keeping only the top right pixel in the block. if it's a single value, then that factor is to be used for both rows and columns.
