Not sure if it will work for your purpose, but as a test I created for
graphic lines, 1 narrow black, 1 wider black, duplicated them and set the
blendlevel of the copies so that they're transparent.
Grcs are named narrowB, wideB, narrowC and wideC (b for black, c for clear)
Then used the following code (and your example string from above with the
WWnNw stuff) to generate a barcode.
on mouseup
put empty into tLast
put field 1 into tChars -- the field with your wNnnW string
set the casesensitive to true -- to differentiate case of course
repeat for each char tChar in tChars
switch tChar
case "N" -- checks the char, and clones the matching bar.
--if its the first time through, places it at a
start location
-- then uses the id of the most recent bar for
placement purposes
clone grc "narrowB"
if tLast is empty then
set the topleft of the last grc to 10,50
else
set the topleft of the last grc to the topright of grc id
tLast
end if
break
case "n"
clone grc "narrowC"
if tLast is empty then
set the topleft of the last grc to 10,50
else
set the topleft of the last grc to the topright of grc id
tLast
end if
break
case "W"
clone grc "wideB"
if tLast is empty then
set the topleft of the last grc to 10,50
else
set the topleft of the last grc to the topright of grc id
tLast
end if
break
case "w"
clone grc "widec"
if tLast is empty then
set the topleft of the last grc to 10,50
else
set the topleft of the last grc to the topright of grc id
tLast
end if
break
end switch
put the short id of the last grc into tLast -- the id of the most
recently placed bar
end repeat
end mouseup
Spacing and line size might need to be tweaked, but it seems like this
would be relatively straight forward.
