The Rasterbator is a free graphic editor designed to create large posters. A mosaic is made with bitmap images (JPG, BMP, GIF, PNG and TIF) of the same size. Using bitmap images on a home printer can be split into small parts, then glued together, making it look like a mosaic. This approach can also use smaller image sizes and produce smaller posters more quickly than large image sizes.
Work with the program is based on a systematic approach - that is, each step of the process is taken in steps.by-In even the most novice of users, this method provides you with the most intuitive results. load the original image and set the poster output size (you can use any one of 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. It is also possible to adjust the output image style (black and white, color, graded to a specific color) and the page orientation (landscape or portrait). The project should be saved in PDF format and it will be printed. By using larger files, converting the images does not take as long.
Create real Wall Paintings from Walls by using theasterbator! I strongly recommend it.
