Hi, A revised code is attached to this email. This one contains a correction from "alpha_min < 1.0" to "alpha_min <= 1.0". ChangeLog entries are as follows. Thanks, Seiji 2008-05-14 Seiji Zenitani , Ryo Yoshitake * frame.c (Qalpha): add a new frame parameter `alpha'. (Vframe_alpha_lower_limit) : new variable. (x_set_alpha): Add function. * frame.h (Qalpha, Vframe_parameter_lower_limit): export them. * xfns.c (x-create-frame, Qalpha): Initialize the frame parameter `alpha'. * xterm.c (x_set_frame_alpha): Add function. * macfns.c (mac_frame_parm_handlers): A null handler for x_set_alpha. * w32fns.c (w32_frame_parm_handlers): Likewise.
