Answer 1

increase the resolution by exactly 2(*2*2*2...) times, this will avoid distortion due to color transitions at the pixel boundaries.
Well, as posters said, "Set the image-rendering property to image-rendering: pixelated;"

resizeMethod: 'resize'
Most likely this mode with the correct resolution (increase by a power of two times) will give a better picture.
