How do you test it, George?

I read questioningly the article of Mr. George Ou, Technical Director of ZDNet, titled as "How can iPhone render pictures better than desktop computers?"

So took an screenshot of his example, with my Desktop Opera on Windows here.

The left picture is zoomed one, from the smallest picture of original, with desktop Opera, and three of the right are his original examples. How do you get the "Nearest neighbor" like picture with Opera?

His article itself is interesting, and maybe worth to read, but the incorrect as far as Opera's concerned, which I must say.

The event I was not presentJoey, not a browser

Strange. I get the same results as you, see it as 170% with the Lanczos_filter (left) versus Opera's zoom (right):

I suspect he had some sort of graphic card (driver) issues on the PC.

Thanks for a fine comment, dantesoft. I suppose he just *see* the zoomed image with *Mobile* Opera, and rapidly concluded all browser except iPhone badly render, to match *his* intentions.
Because he doesn't put real screenshots at all.
And thanks for the link to the ineresting technology.

You get nearest nighbor resizeing in Opera when you turn off
opera:config#Multimedia|InterpolateImages

But that's on by default. (Windows classic 9.22 setup, at least)

/me mumbles something about searching for settings containing "smooth" or "zoom" for exactly that option

But only George Ou would compare Windows’s sub-pixel anti-aliasing to Mac OS X’s non-sub-pixel anti-aliasing and declare that it puts it “to shame”. One minute of Google searching would have shown him that there was something wrong with his example rendering from Mac OS X.
