This Smath document demonstrates the Fourier 0 padding center to zoom
an image matrix. Here, applied to each R,G,B component. This technique
darkens the zoomed image ... luminosity must be zoomed too ! In fact,
you can adjust at will. Though more Edu. than practical, nice to know
how it works under the hood.


CosmosSmall.BMP is the original RGB image
The individual [r,g,b] are file type not allowed.
