The Rasterbator is a free graphic editor designed to create large posters. The program works with bitmap images (JPG, BMP, GIF, PNG and TIF), which can be correctly enlarged to the desired size, divided into small parts for printing on a home printer and glued together into a single whole, like a mosaic. It is also possible to reduce the amount of large images that can be used to prepare small posters for printing.
Work with the program is built on the principle of a step-by-step wizard. This is the easiest and most intuitive method available even to inexperienced users. First of all, you need to load the original image and set the output size of the poster (you can use the standard formats A4, A3, A2, A1 or specify your own size). The Rasterbator will then suggest dividing the web into a certain number of parts of a certain size and setting the gap between the tiles. Optionally, you can adjust the output image style (black and white, color, graded to a specific color) and page orientation (landscape or portrait). After that, the user will have to save the finished project into PDF format and print it out. The process of converting images will not take long, even when using large files.
The Rasterbator is the best program that allows you to quickly create a real wall canvas from a normal image!
