Rasterizer vs. Rasterbator

According to Wikipedia, rasterisation is "the task of taking an image described in a vector graphics format (shapes) and converting it into a raster image (pixels or dots) for output on a video display or printer, or for storage in a bitmap file format."

In the case of Rasterizer and Rasterbator, these software take in an image file as input and blows up the image into a giant poster (in PDF) full of dots of varying sizes to simulate the original image. It's actually half-toning, but let's not get pedantic here.

The Rasterizer (currently v0.7) is a Java program that you download and run from you Mac or PC. You can run it via the CLI or a GUI front-end. With the Rasterbator (v1.21), you can do the rasterisation online by uploading your image or providing a URL, or you download an offline, standalone software.

Both software can do the job, but I prefer Rasterbator as you get a preview before you commit to the final PDF. The online version even overlaps a human figure, so you can estimate how big the final wall art will be.
