OOPPTTIIOONNSS _j_i_g_s_a_w accepts the following options: --wwiinnddooww Draw on a newly-created window. This is the default. --rroooott Draw on the root window. --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. --ddeellaayy _m_i_c_r_o_s_e_c_o_n_d_s How long to wait between shuffling pieces; default 700000, or 0.7 seconds. 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. 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 X Version 11 25-Nov-97 1 XScreenSaver(1) XScreenSaver(1) 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.
