Via Collin’s blog, I found this, the “Rasterbator.” Basically, it allows you to take a graphic that is 1 MB or less and to blow it up to huge proportions– up to 20 meters, according to the web site. It’s a fun fun tool; I just have to figure out where I’d put such a giant poster.
NED Image Printer Driver is a Windows XP/Windows 2000 printer driver that creates multi-page TIFF files and displays them on your screen instead of sending them to your printer. You install the driver the same way you install a Windows printer – no programming required.
