I don't really know why he uses it though.

Can you post what "p
> your_pixbuf.pixels" and "p your_pixbuf.pixels.class" print?

Now we're getting somewhere. I was using puts to print pixels, and all I 
got was a bunch of question marks. p returns a massive String 
(pixels.class shows String). The string itself is uncompressed pixel 
data, a byte per channel of RGBA. The output is a massive string of 
"\000\000\000\000\000\000\000\000..." with "\377" where a pixel is 
drawn, which I'm assumming is 0xFF in the alpha channel (why is \377 
0xFF?).

However, when I tried
>pixels[pixels.length-1] = '\377'
>p pixels
There was no change.
So confused:(

Thanks!
