Image resampling is for texture magnification, whereas mipmap level resampling is for texture minification. The slide implies that we can use the combination of these two methods. How can we magnify and minify a texture at the same time?

@UncooleBen Image resampling is not just for texture magnification, rather it is the method used for sampling an off-grid point from a grid of texture values. We can either take texture value that is nearest to the query point (Nearest) or interpolate near points (eg Bilinear interpolation). This operation is both necessary for texture magnification and for sampling values from a mipmap.
