Overview

I’ve been experimenting with Colour Filter Image manipulation lately. As an example showcasing some of the possibilities I created several images based on the standard orange RSS feed icon.

The following section provides a thumbnails preview of the images I created. Please note that all images have the size dimension of 2000×2000 pixels. I’ve opted to provide high resolution images to accommodate better results should images be edited further. It is not recommended using high resolution images directly due to larger file sizes when compared to typically used lower resolution images. Reducing image resolution is a fairly straight forward task easily achieved using most image editing software.

The first set of images featured in this article were created from the original image by applying ARGB blending filters in a scenario where the source/base image and and overlay image were identical. An article explaining the technical details can be found at C# How to: Blending Bitmap images using colour filters

The last set of images featured were created was by swapping the original image’s ARGB colour channels. To read up on the technical details involved in Bitmap ARGB colour channel swapping you can browse to the following article: C# How to: Swapping Bitmap ARGB Colour Channels
