I looked into this yesterday and discovered that you have to use a
workaround as there are no direct methods to get the colours of a pixel in
Photoshop.
You have to make a selection, call up the histogram and grab the values from
that.
You'll find a useful script from Shane Stanley on the Adobe Forums if you
search for a posting titled "Scripting the color-picker ?"
If anybody knows different, I'd be glad to know about it.
I was hoping to create a script that could parse an image and give me the
CMYK values of the darkest pixels so that I could see if it was greater than
the max ink weight of a specific press.
Products like MarkzScout will do this with TIFF files - but not much else.
I don't really think that selecting each pixel of a 70Mb image, calling the
histogram and storing the values is a workable solution :-(
