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?
1In Photoshop, there's a simple tool called "Background eraser tool" to remove uniform backgrounds like those, by just adjusting the color tolerance of the eraser and then clicking in the background. Not very familiar with Paint.NET, but last time I checked it had a lot of Photoshop-like tools and plugins, maybe there's one with a similar name you can download in order to do that easily. – Ryakna – 2014-10-30T09:36:36.360
