bool _centerVisible

protected

Whether or not the center patch will be drawn

bool _guidesVisible

protected

If true, then "guides" will be drawn". Normally only set in the editor

float _height

protected

Height of the NinePatch in the direction of _radii[1]

bool _needsRecalculate

protected

True when the vertices need to be recalculated

bool _needsTextureRecalculate

protected

True when the texture coordinates need to be recalculated

Vector _normal

protected

Surface normal of the NinePatch. Computed from the _radii

GlsColor _objectColor

protected

Fill color is normally stored in vertices, but we're not using these in GlsNinePatch

Vector _patchTex[ 16 ]

protected

Array of texture coordinates, arranged the same way as _patchVerts

Vertex _patchVerts[ 16 ]

protected

Array of vertices that defines the NinePatch, arranged as follows: 12–13—14—15 | | | | 8-—9—10—11 | | | | 4-—5-—6-—7 | | | | 0-—1-—2-—3

Vector _radii[2]

protected

Radius vectors that define the size of the NinePatch _radii[0] defines the width _radii[1] defines the height

unsigned int _referenceTexHeight

protected

Texture Height when the object was configured. Used to correctly adjust for new texture resolutions.

unsigned int _referenceTexWidth

protected

Texture Width when the object was configured. Used to correctly adjust for new texture resolutions.

unsigned int _texHeight

protected

Texture Height

Vector _textureBLC

protected

Texture coordinate of bottom left corner of NinePatch

float _textureEdge[4]

protected

Values representing the distance from the edge of the texture that makes up the NinePatch borders. Units are in pixels and are the distance IN from the edge of the texture.

Vector _textureTRC

protected

Texture coordinate of top right corner of NinePatch

unsigned int _texWidth

protected

Texture Width

float _vertexEdge[4]

protected

Values representing the size of edges of the NinePatch. Units are in logical units measure going IN from the edge of the NinePatch

float _width

protected

Width of the NinePatch in the direction of _radii[0]
