The Rasterbator is a web service which creates huge rasterized pictures out of relatively small image files. The pictures can be assembled into extremely cool looking posters up to 20 meters in size!
The Rasterbator is very easy to use. You can either upload a file from your computer or use any file that is publicly available in the internet. After you have cropped and selected a desired size for the image, the rasterbated image will be sent to you as an easily printable pdf file.
j-precviously outputs were available only in black and white monochrome. Now, you have the option to choose your monochrome base colour, or a approximate colour match to produce images much like original.
