Detailed Description

Wrapper class of the OpenGL function glCopyTexSubImage.

Is the base class of CopyTexSubImage1D, CopyTexSubImage2D, CopyTexSubImage3D. Copies a rectangular pixels area from the specified read buffer to the specified portion of the texture. Can be bound to a Rendering as a RenderingCallback in order to automatically copy the result of a rendering into a texture, see Rendering.

Note:
This class supports Frame-Buffer-Objects, 3D textures, cubemaps.
