I have been a windows user before i recently got a uMBP and with iWorks09 and Office:Mac 11. For posters and architectural presentation boards, i used Microsoft Publisher, it has 'add transparency' icon within its images toolbar where i could take away single-coloured background or clean up any mess from scanned artwork. Is there any similar feature with iWorks Pages 09? or at least for Office:mac.? Im a new mac user so without this feature and if i had to Photoshop photos prior to me adding it in, it just won't work for me and very time consuming. Or any tips or easy one-off software I could do this with? No Photoshop please.
