Detailed Description

Resource responsible for resizing a texture using the 9-slice technique, for use in UI elements.

The base texture provided to this panel is divided into 9 regions

• The 4 regions at the corners of the texture are locked, and are not resized along with the panel.
• The regions of the top and bottom edges can be stretched or tiled horizontally. Similarly, the left and right edge regions can be extended vertically.
• The region in the center can be resized arbitrarily along both axes along with the panel.

To facilitate this, this aspect computes a new albedo texture and static mesh for the StaticModel component of its SimObject whenever it receives a resize request.

Constructor & Destructor Documentation

NineSlicePanel()

NineSlicePanel::NineSlicePanel	(	std::shared_ptr< ToyMaker::Texture >	baseTexture,
		SDL_FRect	contentRegionUV )

Constructs a new NineSlicePanel aspect.

Parameters

baseTexture	The texture to use as the basis for the panel produced by this aspect.
contentRegionUV	The rectangle, in UV coordinates, of the central region of the rectangle, determining the way the base texture is sliced.
