Yes.

        glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
        glPixelTransferi(GL_MAP_COLOR, GL_TRUE);
        glPixelMapfv(GL_PIXEL_MAP_I_TO_R, 32, color_memory[0]);
        glPixelMapfv(GL_PIXEL_MAP_I_TO_G, 32, color_memory[1]);
        glPixelMapfv(GL_PIXEL_MAP_I_TO_B, 32, color_memory[2]);
        glPixelMapfv(GL_PIXEL_MAP_I_TO_A, 32, color_memory[3]);
