  1. It's also worth noting that this is important from a security standpoint. Redacting information via pixelation is certainly more secure than a standard Gaussian blur, but if you have some idea of what's been pixelated (i.e. it's written text in a particular font and size based on other items on the page) it's not particularly hard to write a script which generates all the possible texts, pixelates them in the same way and correlates that with the original image. Blanking out the area with solid colour is the most reliable redaction tool.
