ovoid setImage(Face, Image* image)
Set the texture image for specified face.

oImage* getImage(Face)
Get the texture image for specified face.

oconst Image* getImage(Face) const
Get the const texture image for specified face.

oinline void setTextureSize(int width, int height) const
Set the texture width and height. If width or height are zero then the repsective size value is calculated from the source image sizes.

oinline void getTextureSize(int& width, int& height) const
Get the texture subload width.

ovoid setSubloadCallback(SubloadCallback* cb)

oSubloadCallback* getSubloadCallback()

oconst SubloadCallback* getSubloadCallback() const

ovoid setNumMipmapLevels(unsigned int num) const
Set the number of mip map levels the the texture has been created with, should only be called within an osg::Texuture::apply() and custom OpenGL texture load

ounsigned int getNumMipmapLevels() const
Get the number of mip map levels the the texture has been created with

ovirtual void apply(State& state) const
On first apply (unless already compiled), create the minmapped texture and bind it, subsequent apply will simple bind to texture

ostatic const Extensions* getExtensions(uint contextID, bool createIfNotInitalized)
Function to call to get the extension of a specified context. If the Exentsion object for that context has not yet been created then and the 'createIfNotInitalized' flag been set to false then returns NULL. If 'createIfNotInitalized' is true then the Extensions object is automatically created. However, in this case the extension object only be created with the graphics context associated with ContextID..

ostatic void setExtensions(uint contextID, Extensions* extensions)
setExtensions allows users to override the extensions across graphics contexts. typically used when you have different extensions supported across graphics pipes but need to ensure that they all use the same low common denominator extensions.
