I have a PNG file that is composed of only two colors: white and dark. Majority of image space is occupied by the white color but I want to remove this white color, thus giving the image a transparent background. I am using Paint.NET and manually erasing just results in an awkward untidy picture. Here comes the image:
Can I do it in paint.NET? Or is there a let's say programmatic way (e.g. using MATLAB) to do it easily?
