How to get the pixel value of texture by per wedge texture coordinate index?

[ziwenjie]

I want get the pixel value of texture by per wedge texture coordinate index, but I can not realize it by the following code.

        ms = meshlab.MeshSet()
        # Load a mesh wi_th texture per wedge
        ms.load_new_mesh(file)
        m = ms.current_mesh()
        wedgecoordMatrix = m.wedge_tex_coord_matrix()
        textures = m.textures()
