For an image with several hundred pixels, how could I process every
pixel on the input image? Do I need an Iterator macro patch for this?
Any advice as always much appreciated. This and the quartz groups
have both been really great I have to say.
An iterator will work, but if you're dealing with more than about 30
pixels you'll have an unusable framerate (the image pixel patch is
pretty slow, esp inside iterators).
There's a plugin called ImagePixel_S or something similar that outputs
a structure of pixel values. This tends to be much much faster (it
only does 1 texture download, instead of 1 per pixel). You can
probably find it by searching this mailing list's archives, or the
kineme.net forums, or even google.
