glslideshow(6) XScreenSaver manual glslideshow(6) NAME glslideshow - slideshow of images using smooth zooming and fades SYNOPSIS glslideshow [--display host:display.screen] [--visual visual] [--win- dow] [--root] [--window-id number] [--duration seconds] [--zoom per- cent] [--pan seconds] [--fade seconds] [--titles] [--letterbox | --clip] [--delay usecs] [--fps] [--debug] [--wireframe] [--cutoff int] DESCRIPTION Loads a random sequence of images and smoothly scans and zooms around in each, fading from pan to pan. This program requires a good video card capable of supporting large textures. To specify the directory that images are loaded from, run xscreen- saver-settings(1) and click on the "Advanced" tab. OPTIONS --visual visual 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. --window Draw on a newly-created window. This is the default. --root Draw on the root window. --window-id number Draw on the specified window. --duration seconds How long each image will be displayed before loading a new one. Default 30 seconds. --pan seconds How long each pan-and-zoom should last. Default 6 seconds. With the default settings of --pan 6 --duration 30, each image will be displayed five times (30/6), and then a new image will be loaded. If you want a new image to be loaded at each fade, then set --pan and --duration to the same value. --fade seconds How long each cross-fade between images should last. Default 2 seconds. If set to 0, then no cross-fading will be done (all transitions will be jump-cuts.) Note that fades are included in the pan time, so --fade cannot be larger than --pan. --zoom number Amount to zoom and pan as a percentage. Default: 75, meaning that 75% or more of each image will always be visible. If set to 100%, then the images will always fill the screen, and no panning or zooming will occur. (Images will still smoothly fade from one to another if --fade is non-zero.) --titles Whether to print the file name of the current image in the up- per left corner. --letterbox In "letterbox" mode, when an image is not the same aspect ratio as the screen, black bars will appear at the top/bottom or left/right so that the whole image can be displayed. This is the default. --clip In "clip" mode, when an image is not the same aspect ratio as the screen, we will zoom in further until the image takes up the whole screen. This is the opposite of --letterbox. --delay number Per-frame delay, in microseconds. Default: 20000 (0.02 sec- onds.). --fps Display the current frame rate, CPU load, and polygon count. --cutoff number If the frame rate we are achieving is lower than this, then panning, fading, and zooming will be disabled. Default 5 FPS. The idea here is that if your machine can't maintain a decent frame rate, then it must not have fast 3D hardware, so we might as well behave in a simpler manner. Set this to 0 to disable this check. --debug Prints debugging info to stderr. --wireframe Another debug mode. ENVIRONMENT DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property. XSCREENSAVER_WINDOW The window ID to use with --root.
