Creating Scalable 9-Patch Bitmap Images

9-Patch is technique used to scale an image in such a way that the 4 corners remain unscaled. The four edges are scaled in one axis and the middle is scaled in both axis. 9-Patch support has been added to Storyboard Designer to make scaling images on embedded applications easier. Instead of having multiple button images of various sizes, customers can now have one image that scales and maintains image quality.


9-Patch images can be designed and edited directly in the Storyboard Design environment. You can quickly analyze and convert existing large or scaled image content to 9-Patch format to achieve immediate memory and runtime performance improvements. In order to be converted to 9-Patch, the source image must have full 32 bit color depth.
