Can someone please explain or provide examples (links) of some valid 9-
patch files?

>From reading the API description, I think my understanding is flawed.

As an example, there's a 9-patch located at: http://www.maladroid.net/test.9.png

[the same idea, as abad ascii representation]

0 = transparent, 1 = black, 2 = red

010101010
102020200
102020200
102020200
102020200
000000000

So there are 3 single-red-pixel columns, with stretchable areas
defined between them. It seems like this should resize to any aspect
ratio and there will still be 3 single-pixel red columns. My thinking
is that the solid black border on the left means "scale uniformly in
the y-direction" and that a pixel in the top row above the transparent
columns means "scale the transparent area, but leave the red columns
with width=1 pixel".

Is that the correct interpretation of black/transparent pixels?

Using the draw9patch tool, it doesn't scale if I make the left-border
completely black, but if I remove any one pixel, then it scales - why
is that?

When working in Eclipse, after refreshing the /drawables folder,
sometimes my 9-patch doesn't show up in the R.java file, presumably
because it is somehow invalid. Yet, I can still refer to it and use it
in the Layout Editor. Am I correct to assume there's something wrong
with the 9-patch? Or perhaps there's something wrong with my (default
eclipse plugin) build process?

Thank you for any suggestions.
