QAbstractTextureImage should be used as the means of providing image data to a QAbstractTexture . It contains the necessary information: mipmap level, layer, cube face load at the proper place data into an OpenGL texture.
The actual data is provided through a QTextureImageDataGenerator that will be executed by Aspect jobs in the backend. QAbstractTextureImage should be subclassed to provide a functor and eventual additional properties needed by the functor to load actual data.
注意: : QAbstractTextureImage should never be shared. Expect crashes, undefined behavior at best if this rule is not respected.
Holds the cube map face of the texture image.
注意: The cube map face has a meaning only for TargetCubeMap and TargetCubeMapArray .
