WaveEngine 2.4.0 includes official native support for NinePatch textures (also known as 9-slice). To know more about what that kind of textures is, read our previous post about it.
As this version allows you to add textures and mark them as “NinePatchType: FromTexture”. This option will be automatically selected if your texture has the extension “*.9.png”.
When this mode is selected, the exporter will extract the stretch and content regions from the texture and remove them from the final asset. Keep it in mind if you need power of two textures (e.g., if your final texture must be 256×256, the source image size must be 258×258)
