I have a 30×30 image, and I resize it to 60×60. All the original pixels now blur into each other due to anti-aliasing. Is there a way to resize the image but keeping the pixelated look, e.g., 1 black pixel becomes 4 black pixels, rather than a blurry mess. Here is an example: I want the increase the size of the left two pixels such that the outcome is what is shown below, so 1x2 pixels becomes 32x64 pixels eventually, while still having the visual effect of looking like a perfect square:
Is there an online / free program that can do this, or perhaps an addon to Paint.NET?
I found How can I resize an image without anti-aliasing?, but it doesn't use Paint.NET So im unsure how to go along with it.
