Using uploaded images, print posters of any size on media of any size.
...Users upload their images and they are first converted to PDFs by tcpdf and then blown up or magnified to the size indicated and then split into panels of media of any size for printing as also chosen by the user. This way a huge poster can be made from regular size paper. Similar projects to this are rasterbator and BlockPoster.
Christerbator is a command-line program that converts images into very large images (in pdf format) that can be printed on regular-sized pieces of paper. This is a java port of the C# version of The Rasterbator from http://arje.net/rasterbator.
