Cool. How would we get the pixel level numeric data into the spreadsheet initially? I assume there is nothing in the macro language that can parse image data at that level. So we'd need to call out to a helper library? Also, one other nice time to have -- not strictly necessary, but would improve the results -- picking an optimal color palette that best matches the colors in the original image. There are some standard algorithms for this: http://en.wikipedia.org/wiki/Color_quantization -Rob > >
