Which part of the documentation you don't understand? From the doc:
Quote: "Setting the Texture Wrap Mode to zero will use the default wrap mode which repeats the pattern of the texture over and over, a mode of one will mirror the texture to create a seamless texture pattern and a mode of two will set clamping which retains the colour of the last pixel at the textures edge and paint with that throughout the out of range area. The Mipmap Generation Flag is used to ensure the image has a mipmap texture. A mipmap is a texture that has many levels of detail, which the matrix can select and use based on the matrix vertex distance from the camera. Use integer values to specify the parameters.
