divide it into 10 equally, or nearly equally wide vertical stripes.
1) For the stripe on the far left you could repeat each pixel 3 times.
2) For the next two stripe repeat each 2 times.
3) Then stripes four through seven are just a normal one:one mapping.
4) The next two stripes would be the same as (2).
5) The final stripe would be the same as (1)
In other words the pattern for repeating pixels would be...
[3,2,2,1,1,1,1,2,2,3]
Dont forget that the vertical also needs to be scaled so your routine gets
to be quite a bit more complicated. Not sure if some kind of a lookup table
might do the trick. Divide the screen into zones and assign each zone a pair
of strech values. You would need to limit the number of pixels per zone to
keep it from becoming visible as a pattern.
He's talking about stretching true 4:3 content, not letterboxed 4:3
content. Therefore, you don't want to stretch the vertical (otherwise,
you're just doing a zoom--which is more appropriate for letterboxed 4:3
content, anyway).
