CMYK to RGB conversion without 3rd party software?

Question

Does anyone know a way to use Automator to convert CMYK color mode images to RGB without having to have Photoshop or such installed? All Automator add ons I have seen thus far involve either Adobe products or other 3rd party image programs.
Thanks!

Answer 1

Hello again Ric,
Thanks for your help. I would appreciate a bit of Applescript help. I have Automator back in the mix after playing around a bit.
Yes, my associate who owns the website has neither PS, or GC. So if we can set up a way to automate this via email that would be great. I think I am actually about half way there, and I hope you will be kind enough to help me get the rest of the way.
My machine is no longer the spunkiest, so I am using GC to do the color mode conversion, as it can launch, convert, and save the file in less than 1/4 the time Photoshop takes to launch. So yes, I'm doing this in a crazy fashion, but I have good reasons.
This is my script thus far:
using terms from application "Mail"
on perform mail action with messages theMessages for rule theRule
tell application "Mail"
set numberOfMessages to count theMessages
repeat with eachMessage in theMessages
set theSubject to subject of eachMessage
try
set nameOfAttachment to the name of the first mail attachment of eachMessage
(*if nameOfAttachment ends with ".torrent" then*)
set filename to "Macintosh HD:Users:parr:Desktop:Alpha Images:•From Brett:" & nameOfAttachment
save first mail attachment of eachMessage in filename
tell application "GraphicConverter"
activate
open {alias filename}
save window 1
close window 1
quit
end tell
tell application "Automator"
execute "Alpha Convert"
end tell
end try
end repeat
end tell
end perform mail action with messages
end using terms from
This works up until I call my Automator workflow. In my workflow I currently have the scale item and the convert to jpeg item.
Question 1: How do we tell Automator what files to use as an input? Do I have to add a Get Selected or Get Specified Finder Items? Can I use the 'filename' variable from the above script?
Once I have that down, any advice you can give on emailing it back would be great.
Thanks again.
