OOPPTTIIOONNSS _s_l_i_p 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. --nnccoolloorrss _i_n_t_e_g_e_r How many colors should be used (if possible). Default 128. The colors used cycle through the hue, making N stops around the color wheel. --ccoouunntt _i_n_t_e_g_e_r How many whooziwhatsis to generate. Default 35. --ccyycclleess _i_n_t_e_g_e_r How long to frobnicate. Default 50. --ddeellaayy _m_i_c_r_o_s_e_c_o_n_d_s How long we should wait between drawing each step. Default 50000, or about 1/20th second. RREESSOOUURRCCEESS On some systems (currently, only SGIs), this program can, instead of grabbing a desktop image, grab a frame of video from an external camera and manipulate that instead. The following resources control that. X Version 11 24-Nov-97 1 XScreenSaver(1) XScreenSaver(1) ggrraabbVViiddeeooPPrroobbaabbiilliittyy (Float) What portion of the time to grab video rather than a screen image, between 0.0 and 1.0. Defaults to 0.5, or half the time. vviiddeeooDDeevviiccee (Integer) The number of the default video input device to check first. If unspecified, the default camera (from videopanel(1)) will be checked first. After that, all other available video input devices will be checked in order. The first one which produces a non-black image will be used. If all images are black, the others will be re-checked a few times before giving up and falling back to simply grabbing a desktop image (but note that this takes a few seconds, so if you don't actually have any video sources hooked up, you should consider turning off video grabbing by setting ggrraabbVViiddeeooPPrroobbaabbiilliittyy to 0.0.) vviiddeeooGGaaiinn (Float) The amount by which to brighten the grabbed image. This defaults to 2.2. 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.
