Because a ninepatch consists of 9 patches, only 5 of which are scaled, while the 4 corners are not scaled. An image that has a black top-left pixel therefore cannot be a ninepatch image. The draw9patch tool shouldn't even let you set the top-left to black. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
