Thanks guys. Here are the results so far...
I've tried to copy to LO Impress, and LO Drawing. Impress crashed. Drawing froze for an eternity before copying over. I managed to save as a png, but lost so much quality it was unworkable.
I have converted to pdf, but it's on 3 pages. I've not lost quality, but am struggling to do much with it.
I am doing all this on the low powered netbook mentioned in my signature. My main PC with all the power and screen space is out of action atm. I need to try inkscape but haven't played with it in years.
Any help with any of it would be appreciated.
