Throwing out another example, how about this -- it's more verbose, but probably a lot
faster for large inputs:
put the imagedata of image tSomeImage into tStr
put 0 into tCharCount
put empty into tColors
repeat for each char X in tStr
add 1 to tCharCount
switch tCharCount
case 1
break
case 4
put charToNum(X) & cr after tColors
put 0 into tCharCount
break
default
put charToNum(X) & "," after tColors
end switch
end repeat
put tColors into fld tSomeField
