Custom Frame Texture Coordinate Width

Introduction

The Custom Frame Texture Coordinate Width property allows a NineSlice to customize the number of pixels used on the source texture when defining its outer frame. This allows for fine control over which parts of a NineSlice stretch and which parts are used as the corners and edges.

By default this value is null, which means the NineSlice automatically dedicates 1/3 of the texture for the edges.

Changing Custom Frame Texture Coordinate Width

If the Custom Frame Texture Coordinate Width value is changed, then the source texture applies a fixed pixel size to the borders. For example, using the image above, the frame can be changed to 3 so that only the black and white pixels are part of the border.

Custom Frame Texture Coordinate Width Set to 0

If Custom Frame Texture Coordinate Width is set to a value of 0, then the NineSlice does not draw a border. In other words, setting this value to 0 results in the NineSlice behaving like a Sprite.
