haven't testet the code, but did you try it without setting the
smoothing property (on the
bitmapdata object)?

Hi, Im breaking an image into a grid of separate clips with
corresponding
pixels using copyPixels but I'm getting gaps in between the clips.
Also sometimes the image wont finish if the ratio between horz and
vert
clips is too high. Has anyone had this issue.
code below
cheers, MaTT
