This is truly the swiss army chainsaw of qix programs. If you know of one with more display modes, I want to know about it. OOPPTTIIOONNSS _q_i_x accepts the following options: --wwiinnddooww Draw on a newly-created window. This is the default. --rroooott Draw on the root window. --mmoonnoo If on a color display, pretend we're on a monochrome display. --iinnssttaallll Install a private colormap for the window. --vviissuuaall _v_i_s_u_a_l Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. --sseeggmmeennttss _i_n_t_e_g_e_r How many line segments should be drawn. Default 50. --sspprreeaadd _i_n_t_e_g_e_r How far apart the endpoints of one segment should be from the next. Default 8. --ssiizzee _i_n_t_e_g_e_r The maximum distance one endpoint of a segment is allowed to be from the opposite end of that seg- ment. Default 0, meaning unlimited. --ccoouunntt _i_n_t_e_g_e_r How many qixes to draw. Default 1. X Version 11 27-Apr-97 1 XScreenSaver(1) XScreenSaver(1) --ccoolloorr--sshhiifftt _d_e_g_r_e_e_s If on a color display, the color of the line seg- ments will cycle through the spectrum. This spec- ifies how far the hue of each segment should be from the next, in degrees on the HSV wheel. Default 3. --ddeellaayy _m_i_c_r_o_s_e_c_o_n_d_s How much of a delay should be introduced between steps of the animation. Default 25000, or about 0.025 seconds. --rraannddoomm The _q_i_x will wander around the screen semi-ran- domly. This is the default. --lliinneeaarr The opposite of _-_r_a_n_d_o_m: the _q_i_x will travel in straight lines until it reaches a wall, and then it will bounce. --ssoolliidd If this is specified, then the area between the line segments will be filled in with the appropri- ate color, instead of the _q_i_x simply being com- posed of one-pixel-wide line segments. This option looks really good in color. --hhoollllooww The opposite of _-_s_o_l_i_d; this is the default. --xxoorr If this is specified, then qix segments will be drawn and erased with xor, instead of being drawn in some color and erased in the background color. This implies _-_m_o_n_o, in that only two colors can be used. --ttrraannssppaarreenntt If this is specified, and _-_c_o_u_n_t is greater than 1, then each qix will be drawn in one color, and when they overlap, the colors will be mixed. This looks best in conjuction with _-_s_o_l_i_d. --nnoonn--ttrraannssppaarreenntt Turns off _-_t_r_a_n_s_p_a_r_e_n_t. --aaddddiittiivvee If _-_t_r_a_n_s_p_a_r_e_n_t is specified, then this option means that the colors will be mixed using an addi- tive color model, as if the qixes were projected light. This is the default. --ssuubbttrraaccttiivvee If _-_t_r_a_n_s_p_a_r_e_n_t is specified, then this option means that the colors will be mixed using a sub- tractive color model, as if the qixes were translucent filters. X Version 11 27-Apr-97 2 XScreenSaver(1) XScreenSaver(1) --ppoollyy _i_n_t How many vertices each qix-line should have: the default is 2, meaning the traditional qix line shape. Three will yield triangles, and so on. --ggrraavviittyy --nnoo--ggrraavviittyy Whether there should be downward attraction. For example, the options --ggrraavviittyy --lliinneeaarr will make everything move in nice smooth parabolas. Gravity is off by default. EENNVVIIRROONNMMEENNTT DDIISSPPLLAAYY to get the default host and display number. XXEENNVVIIRROONNMMEENNTT to get the name of a resource file that overrides the global resources stored in the RESOURCE_MAN- AGER property.
