Image Filters: Ram Chips

Overview

Lately I’ve developed and published a fair amount of code and technical articles relating to implementing image colour filtering. I’ve decided to start publishing images manipulated by the methods of colour filtering I’ve discussed.

Quite often it is the case that software labelled as open source serve very little practical use, apart from being academic resources. I intend to illustrate through this article and related articles yet to be published that the concepts I examined in my open source sample articles do indeed have a practical application.

The colour filter implemented in this article was achieved by swapping the original image’s ARGB colour channels. To read up on the technical details involved in ARGB colour channel swapping you can read the following article:
