Detailed Description

A class for paring Android .9 patch image.

For more about Android .9 patch image format, please refer to http://developer.android.com/tools/help/draw9patch.html

The class could parse a single .9 patch image and produce the capInsets as well as a sprite atlas and store all the capInsets infos in a Texture2D. Note:

• Currently only PixelFormat::RGBA8888 is supported.
• TexturePacker Trim mode is not supported at the moment.
