Thanks for your responses.
I know I can fix this by creating a high density image, but in the
first place, the reason I didn’t do it is because my application is
working on version 1.5, which, as you probably know, does not support
density-specific resources.
I have more than one way to solve this problem, one of them is as you
suggested, but I’m still interested to know the difference between a
regular PNG and a 9-patch PNG, when it comes to scaling up.
Thanks again
